Runs entirely inside your infrastructure. No third-party model dependency, no per-minute API fee, no audio leaving the building. Compare Resident → Why Resident Voice AI The world changed. The old way broke. 1 · The world changed Every business now receives more inbound conversation than it has humans to answer — and callers judge you in the first second of silence. 2 · The old way broke Cloud voice AI made agents possible, but it sends every word of every call to somebody else's servers and charges per minute, forever. 3 · Which means The businesses with the most calls and the most sensitive data — hospitals, labs, legal — are either locked out, or carrying a risk nobody has priced. 4 · There is another way A voice agent should answer in under half a second and run wherever you need it to — including entirely inside your own building. 5 · So we built Resident Voice AI. One agent, two editions: 350 ms in the cloud, 355 ms inside your building — measured, with the method published. The proof narrative Live in a working hospital A hospital like yours was losing calls every day. Anuvo answers them all now — and the front desk is no longer the bottleneck. "Patients used to call three times and give up. Now every call gets answered on the first ring — in the caller's language — and the front desk's work shifted from answering to caring." Front-desk team, VS Hospitals · production deployment 355 ms measured answer, method published 100% of calls answered — none lost to voicemail 3 languages live on the same lines 0 bytes of audio leave the building We lead with the patient who called three times and gave up. The millisecond figure is our proof, not our pitch. Outcomes are reported by the deployment, not a demo. Detailed deployment story on the Healthcare page .

No forced telemetry. Read the security page Read the docs Straight answers Frequently asked What is Anuvo? Anuvo is Resident Voice AI: a voice agent that answers inbound calls in under half a second, books appointments, and speaks the caller's language. It runs in the cloud or entirely inside your own infrastructure. How fast is it, really? Measured end-to-end from call connect to first useful response: 350 ms on Anuvo Cloud, 355 ms on Anuvo Resident. We publish the method and the honest caveats on the latency benchmark page — engineers can verify rather than trust. Does Resident send audio anywhere? No. Anuvo Resident runs entirely inside the customer's infrastructure with no third-party model dependency: no per-minute API fee, no vendor repricing risk, and no audio leaving the building. Which languages? Anuvo is multilingual including Indian languages — English, Hindi and regional languages configured per line. The hospital deployment runs intake in three languages on the same lines. How do we get started? Call the demo line, then plan your deployment. For Resident we scope the integration with your PBX or SIP trunk, your HIS/CRM, and your compliance requirements — typically live in days, not months. What's the difference between an IVR and an AI voice agent? An IVR is a menu tree — it makes the caller do the work by pressing keys. An AI voice agent understands speech, answers in plain language in under half a second, and takes actions like booking appointments. IVRs cost callers seconds of silence; Anuvo answers with none. Which is better for business calls: hosted or self-hosted voice AI? Hosted (Anuvo Cloud, 350 ms) is fastest to live and needs zero infrastructure. Self-hosted (Anuvo Resident, 355 ms) is for data you are not allowed to send anywhere — hospitals, labs, legal. Both run the same agent; the choice is where the audio is allowed to go. Missed calls pay for the license A hospital like yours is losing calls right now. One call a day that never gets answered pays for the month.

The best AI voice agents answer calls end-to-end in under 400 ms, recover when interrupted mid-sentence, and run wherever your data allows — including entirely inside your building. Anuvo measures 350 ms on Cloud and 355 ms self-hosted, with the method published. This page is the evaluation checklist we wish buyers had before the demo. Skip the features list — here is what actually separates a voice agent that sounds human from one that sounds like a robot. Hear one right now See the measured numbers What to measure The five signals that separate great voice AI from demos Every vendor can demo a voice agent. Very few publish numbers you can verify. Evaluate on these five, in this order. 1 · End-to-end latency, not inference time Ask for time from call connect to first useful response — not model-inference-only. Above 400 ms, callers perceive the agent as slow or broken. Anuvo: 350 ms Cloud, 355 ms Resident, p50, method published on the latency page . 2 · Barge-in, tested by interruption Interrupt the agent mid-sentence on the first call. Does it yield instantly and recover in context, or restart the turn? Barge-in is the power-user test — technical buyers always run it. 3 · Multilingual, per line In India, the caller speaks the language, not the product. A single line should answer in English, switch to Hindi on request, and serve regional languages — within the same latency budget, no translation hop. 4 · Data residency, in writing Where does the audio go? If the answer is "our servers, per minute, forever", regulated buyers are carrying un-priced risk. A self-hosted edition that runs inside your network removes the question entirely. 5 · Integrations on the post-answer path Booking and HIS/CRM writes must run after the answer, off the latency critical path. A slow API should never add to the caller's wait — check the architecture, not the brochure. Where Anuvo lands on all five 350 ms / 355 ms measured · barge-in on every line · English + Hindi + regional, per line · Resident runs inside your building with zero audio egress · integrations run post-answer. Read the docs and verify. Buy vs build Buying beats building — here is the math A voice agent is not a model call. It is a latency-budgeted pipeline: media ingress, speech recognition, intent understanding, response generation, synthesis, media egress, plus barge-in handling, an audit log, and integrations. The measured budget is enforced across every hop. Build it yourself Buy Anuvo Time to first answered call 6–12 months of engineering Days (Cloud) · weeks, scoped (Resident) Latency budget You own every hop's jitter Enforced end-to-end, 350–355 ms measured Barge-in & recovery Months of edge-case work Built in, testable on the demo line Multilingual Per-language pipeline work Configured per line Residency You could — but on top of everything else Resident runs in your network, no egress Ongoing cost Voice/ML ops team, forever Per-minute (Cloud) or flat license (Resident) Build when the voice agent is the product. Buy when it's a channel — and almost every hospital, clinic, lab and intake desk is the second case. Use the architecture planner to scope the deployment before you talk to sales. The categories Cloud voice agents vs Resident Voice AI Most voice agents live in someone else's cloud and charge per minute, forever. That works for commercial buyers and breaks for regulated ones. Cloud voice agents Anuvo Cloud Zero infrastructure, fastest to live, per-minute billing. Right for speed-driven commercial teams with variable volume. Anuvo Cloud does this in 350 ms . Resident Voice AI Anuvo Resident The agent is resident on your infrastructure — and in a hospital, the resident is the one who is always there. 355 ms measured, no third-party model dependency, no audio leaving the building. Anuvo Resident . The short version: if you search "best AI voice agent" and your compliance team would veto "audio to a third party's servers", the best agent for you is the one that runs where your data is allowed to go. That is the category Anuvo named. Straight answers Asked on every evaluation call How fast is a good AI voice agent? Below 400 ms end-to-end from call connect to first useful response. Above that, callers perceive the agent as slow. Anuvo measures 350 ms (Cloud) and 355 ms (Resident) with the method published on the benchmark page . Can an AI voice agent handle interruptions? A good one can — barge-in, tested by interrupting it mid-sentence. Anuvo yields the turn instantly and re-interprets in context, and you can test it yourself on the demo line . Does voice AI have to send my calls to the cloud? No. Anuvo Resident runs the entire stack inside your network: no third-party model dependency, no per-minute API fee, no audio leaving the building. See the data residency page . Is Anuvo live in production? Yes — live in a working hospital, answering front-desk calls and booking appointments in multiple languages. The deployment story is documented. The demo is a phone number Call it. Interrupt it. Judge it. No form, no sign-up — the product is the pitch.

Anuvo Resident is the self-hosted edition: a voice agent that runs entirely inside your infrastructure, answers in 355 ms — measured — and has no third-party model dependency at all. Most on-premise voice stacks sit above a second of latency. Anuvo Resident delivers sub-400 ms answers inside your own network — no per-minute API fee, no vendor repricing risk, no audio leaving the building. This is the edition that unlocks regulated buyers: hospitals, labs, legal. Plan your Resident deployment Security & data residency PSTN / SIP trunk in PBX stays yours — no rip & replace 355 ms measured, method published 0 bytes leave the building No third-party model dependency Annual license — no per-minute fee HIS / EHR / CRM writes in-network Audit log on your store 355 ms measured end-to-end, self-hosted 0 third-party model dependencies ₹0 per-minute fee — annual license only 0 bytes of audio leave your network, ever Why Resident exists The businesses with the most calls and the most sensitive data were locked out Cloud voice AI sends every word of every call to somebody else's servers and charges per minute, forever. For a hospital, a lab or a law firm that is a compliance problem dressed as a convenience — so the businesses that need a voice agent most were carrying a risk nobody had priced. Anuvo Resident removes the trade. The entire stack — speech recognition, synthesis, orchestration, audit log — runs on hardware you control. What the cloud edition does for a commercial buyer, Resident does for a regulated one. Data residency, by design Audio, transcripts and metadata live and die on your network. Compliance stops being the reason you cannot use AI. Sub-second, on-premise 355 ms measured inside the customer network — not a marketing number, a benchmark with a published method. No vendor repricing risk Your inference cost is your hardware cost. No model vendor can reprice your per-minute bill out from under you. Multilingual, on your floor English, Hindi and regional languages run locally. Intake, booking and FAQs in the caller's language, per line. Integrates with what you run PBX or SIP trunk in, HIS / EHR / CRM out via REST and webhooks. The agent books into your systems, not ours. Audit logging you control Every call recorded with consent, every action logged, RBAC enforced — and the log never leaves your network either. How it runs One appliance or your existing Kubernetes — your call Anuvo Resident deploys as a packaged stack: a single appliance for most sites, or a Helm chart into an existing cluster for teams that already run one. The architecture is identical either way. 1 · Telephony ingress Your existing PBX or SIP trunk routes inbound calls to the Resident media server — no phone system replacement. ↓ 2 · Anuvo Resident runtime STT → orchestration → TTS, all in-process on your hardware. Latency budget enforced end-to-end: 355 ms measured. ↓ 3 · Actions and integrations Appointment booking, HIS/EHR updates, CRM writes — outbound REST and webhooks to systems already in your network. ↓ 4 · Audit and telemetry Call audio (with consent), transcripts and metadata to your audit store. Optional: metadata-only relay to Anuvo Cloud for dashboards — never audio. Resident ≠ slower. The myth that on-premise voice stacks sit above a second is why we publish the benchmark: 355 ms inside the customer network, method included, on the latency page . Sizing guidance What a deployment needs Site size Hardware profile Throughput Notes Clinic / small practice 1 appliance (GPU-optional, CPU-capable) ~4–6 concurrent calls Single box, single number, multilingual lines.

Point your number at Anuvo Cloud and the agent is live. No servers, no model ops, no monitoring rota. Per-minute billing Transparent per-minute pricing plus one-time setup. No minimums that punish slow months, no surprise line items. Data you can audit Call recordings with consent, transcripts and metadata in your dashboard, exportable. Retention and access policies you control. Know the boundary When to choose Cloud — and when not to Choose Anuvo Cloud when… Choose Anuvo Resident instead when… You want the agent live this week and don't want to run infrastructure. Your compliance policy says patient or client audio may not leave your network — ever. Your call volume is variable and per-minute billing matches your cost model. You want a fixed cost with no per-minute fee, and predictable spend. Your team has no dedicated voice/ML ops and you'd rather not hire any. You need no third-party model dependency and no vendor repricing risk. Your data is not regulated, or your regulator accepts a hosted model. You want the audio to never leave the building, full stop. Both editions run the same agent with the same measured behaviour. If you start on Cloud and outgrow it on compliance, moving to Resident is a reconfiguration, not a rebuild. Use the architecture planner to see which fits. What it answers Cloud runs on the same five beats Every call follows the same measured flow — that is what makes the 350 ms figure reproducible rather than a demo trick. Connect Call lands on your number via PSTN or SIP. Anuvo Cloud answers on the first ring — no IVR menu, no "press 1". Listen for intent Barge-in aware: the caller can interrupt at any point and the agent recovers mid-sentence, not after a long silence. Answer and act Appointments booked, FAQs answered, escalations routed. Every action is a webhook or API call you can see in the audit log. Hand off Human on request, call-back scheduled, or a follow-up SMS with the booking confirmation in the caller's language.

Our numbers come with a published method you can reproduce . Retell pricing is per-minute and varies by voice engine and LLM; check their pricing page for current terms. When each wins How to decide, in one afternoon Choose a cloud voice platform (Retell or Anuvo Cloud) when… You want the fastest path to a live agent and don't want to run infrastructure. Your data is not regulated, or your regulator accepts a hosted model. You want a no-code studio and a large integration ecosystem. You want to bring your own LLM and pay strictly per minute with no monthly commitment. Choose Anuvo Resident when… Your compliance policy forbids patient or client audio leaving your network — hospitals, labs, legal. You want a fixed cost with no per-minute fee, and no vendor repricing risk. You want measured sub-400 ms latency with the method published. You want zero third-party model dependency and full audit control. The decision rule: if "where does the audio go?" is a question you must answer in a procurement document, Resident is the category. If you just want calls answered this week — or you value a no-code studio and BYO-LLM flexibility — Cloud gets you there in days, and Retell's tooling is genuinely good. The architecture planner recommends from your actual volume and compliance answers.

Anuvo Resident is self-hosted voice AI: speech recognition, orchestration and synthesis all run on your hardware, with no third-party model dependency and no audio leaving the building. Measured end-to-end: 355 ms. The old assumption — that on-premise voice stacks sit above a second of latency — is exactly the myth we built Resident to break. Residency and speed are not a trade-off. Size your on-premise deployment How the data stays put Why self-hosted When "the cloud" is the answer nobody can sign Cloud voice AI made agents possible, but it sends every word of every call to somebody else's servers and charges per minute, forever. For hospitals, labs, law firms and public-sector buyers, that is a compliance problem dressed as a convenience. No audio egress Audio, transcripts and metadata resolve inside your network. "Where does the audio go?" — nowhere. No vendor repricing risk Your inference cost is your hardware cost. No model vendor can reprice your per-minute bill out from under you. 355 ms, on your floor Sub-400 ms is not a cloud-only trick. The same latency budget runs in your building — see the benchmark method . How it runs What "self-hosted" actually means here A packaged stack, not a research project: one appliance for most sites, or a Helm chart into your existing cluster. Same agent behaviour as Cloud — different physics.

Measured end-to-end, from call connect to first useful response: 350 ms on Anuvo Cloud, 355 ms on Anuvo Resident. Here is the method, the chart, and the caveats. We publish this page because engineers don't trust marketing numbers — and we'd rather you verify us than argue with us. This page is written to be quoted, cited and linked.

Contact us for the raw per-call distribution. The method What we measure, and how A latency figure is only as honest as its definition. Here is ours, written so you can reproduce it. Definition Latency = time from call connect (the instant the caller's media flow is established) to the start of the first useful response — the first syllable of speech that answers the caller. It is not time-to-hear-a-tone, and it is not model-inference-only. Pipeline measured The full path: media ingress → speech recognition → intent understanding → response generation → speech synthesis → media egress. Every hop is inside the measured window, because that is the window the caller experiences. Instrumentation Both editions report a per-call latency distribution from production telemetry: p50, p90 and p99. The headline figure is the p50 . We will publish the raw distribution with the first production cohort. Conditions Measured on a standard call: caller speaks a typical opening phrase ("I'd like to book an appointment"). Language: English and Hindi tested; regional languages tracked separately. Network: wired broadband, sub-40 ms RTT to the runtime. The honest caveats Where the number does and doesn't hold Factor Effect on latency Our position Poor network / satellite links +50–200 ms Budget the last mile; Resident is unaffected by public network jitter. Heavy background noise +p99 variance, not p50 Recognition re-attempts add to the tail, rarely to the median. Very long or unusual caller phrasing +100–300 ms Barge-in recovers mid-sentence; the budget is enforced per-turn. Under-provisioned Resident hardware Degrades the whole curve Sizing guidance in the planner prevents this before it happens. Third-party integrations on the response path +integration time Booking/HIS calls run post-answer, off the latency critical path. The quotable sentence: "Anuvo Resident answers in 355 ms with no audio leaving the customer network." Use it, cite the method, and hold us to it. Why it matters The first second of silence is a verdict Callers judge you in the first second of silence. Above 400 ms, a caller perceives the agent as slow or broken; below it, the response feels like a person picking up. Sub-400 ms is not a vanity metric — it is the difference between a caller staying on the line and hanging up. And the self-hosted number matters for a different reason: most on-premise voice stacks sit above a second. Resident proves that residency and speed are not a trade-off.

Anuvo answers every inbound call to your front desk in under half a second, books the appointment in the caller's language, and — on Resident — the audio never leaves your building. The front desk is one human deep. When that human is on another call, every other caller hears silence and many hang up. Anuvo is the resident that is always there: it answers, listens, books, and only hands off when the caller asks for a person. Hear it answer a call Read the VS Hospitals story What it fixes Three failures, one agent Missed calls Overflow calls ring out or hit a busy tone. Patients call three times and give up — and give up on the hospital, not the phone. Language barriers Callers who don't speak English well get passed around or give up. Anuvo answers in English, Hindi and regional languages on the same line. The front-desk bottleneck Every routine booking occupies a human. Anuvo absorbs the routine so the desk's time goes to callers who actually need a person. The proof narrative Live in a working hospital A hospital like yours → what it was losing → what changed → the measured result. Before VS Hospitals ran a single front-desk line. Inbound volume exceeded what one human could absorb, so calls backed up, rang out, or hit busy tones. Patients called three times and gave up — no booking, no record, no follow-up. The desk had no way to know how many calls were lost, only that the queue was always full. After Anuvo answers every call on the first ring, in under 400 ms, in the caller's language. It books appointments into the hospital's own scheduling system, answers routine questions, and transfers to a human on request. The front desk stopped being the bottleneck; its time went back to callers who needed a person. The measured result: no patient call goes unanswered, and appointment booking runs in three languages on the same lines — with Resident, all of it inside the hospital's infrastructure. What it handles A call, start to finish 1 · Answers on the first ring "Good morning, VS Hospitals. How can I help?" — in the caller's language, with no IVR menu and no dead air. 2 · Books the appointment Collects department, doctor, date preference and patient details, then writes the booking to the HIS — caller gets a confirmation SMS. 3 · Answers routine questions Timings, location, OPD charges, document requirements — answered from your approved knowledge base, not improvised. 4 · Hands off on request "Can I speak to a person?" — warm transfer to a human with the context already captured. No repetition, no re-explaining. Plan a healthcare deployment See how patient data stays put For the procurement office The questions they will ask, answered Where does patient audio go? On Anuvo Resident, nowhere. The whole stack runs inside your network: no third-party model dependency, no audio egress, no per-minute API fee. Metadata-only dashboards are optional and never carry audio. How is consent handled? Calls are recorded and transcribed only with the announcement-and-consent flow you configure. Retention windows, access control (RBAC) and export are in your control, on your audit store. Does it integrate with our HIS? Yes — booking and patient lookups run against your existing HIS/EHR/CRM via REST and webhooks. We scope the integration in the deployment plan; the architecture planner shows the wiring. What if the caller insists on a human? Warm transfer with context, always available. Anuvo is designed to escalate, not to trap callers in an agent loop.

On Resident, plan a deployment with the architecture planner first. Cloud, in three steps Create an agent — name it, set languages and the knowledge base (your FAQs, timings, booking rules). Attach a number — bring your own number (port it or set a forward) or request one. SIP trunking or PSTN forwarding, both supported. Call it. The agent answers on the first ring, in under 400 ms, barge-in aware. Resident, in one paragraph Resident ships as a packaged stack — a single appliance for most sites or a Helm chart into an existing cluster. The runtime contains STT, orchestration and TTS in-process; your PBX routes calls to it over SIP; it writes bookings and audits into your own systems. Measured: 355 ms, inside your network. # Create an agent (Cloud) curl -X POST https://api.anuvo.ai/v1/agents \ -H "Authorization: Bearer $ANUVO_API_KEY" \ -H "Content-Type: application/json" \ -d '{ "name": "Front Desk", "languages": ["en-IN", "hi-IN"], "knowledge_base": "kb_front_desk_v1", "barge_in": true, "latency_budget_ms": 400 }' Cloud vs Resident Both editions run the same agent with the same measured behaviour; they differ only in where inference runs and how you are billed. Anuvo Cloud Anuvo Resident Latency (measured) 350 ms 355 ms Inference location Anuvo-managed region Your infrastructure Audio egress Yes, to our runtime Never Billing Per-minute + setup Annual license Time to live Days Weeks, scoped If your compliance policy forbids patient or client audio leaving your network, Resident is the edition that fits the rule. Otherwise Cloud gets you live fastest. Moving later is a reconfiguration, not a rebuild. Phone number & SIP setup Anuvo connects over PSTN forwarding or SIP trunking; you keep your existing number in both cases. PSTN forwarding — forward your existing number to the Anuvo ingress. Fastest to live; works with any provider. SIP trunk — for Resident, your PBX/SBC routes calls to the Resident media server over SIP inside your network. No phone system replacement. Porting — we can help port a number to a carrier with direct SIP, if you want one less hop. On Cloud, choose the region your calls terminate in — region choice affects the last hop of latency more than anything else. The latency budget Anuvo enforces a 400 ms end-to-end budget from call connect to first useful response; the measured p50 is 350 ms on Cloud and 355 ms on Resident. The budget is a product decision, not a benchmark boast. Callers judge you in the first second of silence — above 400 ms a caller perceives the agent as slow or broken. The runtime enforces the budget per turn: recognition, understanding and synthesis run as a streaming pipeline, and the first response is generated from partial transcripts rather than waiting for silence. What is on the critical path: media ingress, STT, intent, TTS, media egress. What is not : integrations. Booking and HIS writes run post-answer so a slow API never adds to the caller's wait. The full method and caveats are on the latency page . Barge-in Callers can interrupt Anuvo mid-sentence at any point, and the agent recovers instantly — no dead air, no "I didn't catch that". Barge-in is the power-user signal of voice AI: technical buyers test it in the first call. Anuvo detects interruption within the media pipeline and yields the turn immediately; the interrupted utterance is re-interpreted in context. Recovery latency is part of the measured budget — you can test it yourself on the demo line . { "barge_in": true, "barge_in_sensitivity": "normal", "recovery": "contextual" // re-interpret in context, not restart } Multilingual lines Anuvo is multilingual including Indian languages — English, Hindi and regional languages configured per line, so a single number can serve many callers. Language is set per line, not per agent: a hospital front-desk number can answer in English, switch to Hindi on request, and serve regional languages the caller actually speaks. Detection and synthesis run inside the same latency budget; there is no translation hop. "languages": ["en-IN", "hi-IN", "te-IN", "ta-IN"] Data residency On Anuvo Resident, call audio never leaves your network: no third-party model dependency, no data egress, no per-minute API fee. Resident makes no outbound calls that carry audio. Recognition, orchestration, synthesis, transcripts and the audit log all resolve inside your boundary. The optional Cloud relay is metadata-only — dashboards and fleet analytics, never audio, never transcripts unless you explicitly opt in. See the security page for the architecture diagram and controls. Authentication All API requests authenticate with a bearer token; tokens are scoped to roles and can be rotated without downtime. Authorization: Bearer $ANUVO_API_KEY Tokens are issued per role — operator, supervisor, auditor — and every token's usage lands in the audit log.

Crux-Voice Engine Architecture — CruxLabx Technologies Anuvo is powered exclusively by the Crux-Voice Engine, engineered by CruxLabx Technologies Pvt Ltd for ultra-low latency, enterprise telephony, and complete sovereign data isolation. Core Engine Specifications Latency Budget: Sub-400 ms measured round-trip audio turnaround (350 ms Cloud / 355 ms Resident on-premise). Transport & Telephony: Direct LiveKit WebRTC media transport, native SIP trunking (Kamailio / FreeSWITCH / Asterisk), and Twilio/Telnyx media streams. Multilingual Speech Pipeline: Streaming neural ASR + Native Audio LLM orchestration + low-latency TTS tuned for Indian dialects (English-IN, Tamil, Hindi, Telugu, Odia). Sovereign On-Premise Stack: Single-binary or Helm deployment running STT, LLM inference, and TTS inside the customer boundary — 0 bytes of audio leave the facility. Enterprise Integrations: Instant read/write access to hospital HIS/EHR, appointment booking calendars, and CRMs over secure internal APIs. # Crux-Voice Engine Integration (CruxLabx Technologies) from cruxlabx.voice import CruxVoiceEngine, CallSession engine = CruxVoiceEngine( model="crux-voice-v2", transport="webrtc", sample_rate=24000, residency="on_premise" # 0 bytes audio egress ) @engine.on_call async def handle_inbound(call: CallSession): await call.answer(persona="Hospital Front Desk", languages=["en-IN", "ta-IN", "hi-IN"]) Webhooks & events Anuvo fires webhooks for the events that matter — booking confirmed, call escalated, outbound follow-up scheduled. { "event": "booking.confirmed", "call_id": "call_8f2a", "payload": { "department": "cardiology", "appointment_at": "2026-08-14T09:30:00+05:30", "patient": { "phone": "+919876543210", "language": "hi-IN" } } } Events are delivered with retries and an idempotency key; integrations should be safe to replay. Signature verification: X-Anuvo-Signature: HMAC-SHA256(body, secret) . SDKs Official SDKs for Node.js and Python wrap the full REST API; anything else can use the documented HTTP endpoints directly. # Node.js import { Anuvo } from "@anuvo/sdk"; const anuvo = new Anuvo({ apiKey: process.env.ANUVO_API_KEY }); # Python from anuvo import Anuvo anuvo = Anuvo(api_key=os.environ["ANUVO_API_KEY"]) SDKs cover agents, calls, webhooks and audit, with typed responses and automatic retry/backoff. TypeScript types ship with the Node SDK. Security & compliance Anuvo encrypts in transit and at rest, enforces RBAC, records with consent, and on Resident keeps everything inside your network. Encryption: TLS 1.3 in transit; AES-256 at rest for recordings and transcripts. On Resident, keys live on your infrastructure. Consent: configurable announcement-and-consent flow per line; recordings are consent-gated. Retention: retention windows, deletion and export under your administration. RBAC: operator / supervisor / auditor roles, least privilege, full audit trail. Residency: Resident has no audio egress — relevant to DPDP-aligned and healthcare data policies.

Strong brands lead with emotion, story and recognition. This is where we make the argument — five beats at a time, without jargon. Field note 01 · Latency The call that changed our latency budget Written the way a person would say it out loud. Direct, grounded, human. We used to think voice AI was a model problem. Then we watched a patient call a hospital, hear nothing for a full second, and hang up. Not because the model was wrong — because it was slow. The caller didn't judge the answer; they judged the silence before it. That's when we stopped measuring inference time and started measuring the whole thing: from the moment a call connects to the first syllable the caller hears. That number — the gap that doesn't exist — became our product. 350 ms on Cloud, 355 ms on Resident, both measured end-to-end, method published. Callers judge you in the first second of silence. We built Anuvo so that second never happens. Field note 02 · Residency Why the audio never leaves The argument, in answer shape. Cloud voice AI made agents possible, and it also made a quiet promise it can't keep: that sending every word of every patient call to somebody else's servers, forever, at a per-minute price, is fine. For a hospital, a lab or a law firm it isn't fine. Their data is regulated, their callers are vulnerable, and their compliance team gets a vote. So the businesses that need a voice agent the most were locked out of the category — or worse, carrying a risk nobody had priced. That is why Resident exists. The entire stack — recognition, orchestration, synthesis, the audit log — runs inside your building. No third-party model dependency. No per-minute fee. No audio leaving your network, ever. Residency and speed are not a trade-off; 355 ms measured, inside your four walls. Field note 03 · Category "Resident Voice AI" is not a category. Yet. Why we're naming the shelf we want to own. The "AI voice agent" category is crowded, well funded, and priced downward by companies with more capital than sense. Entering it means competing on price against people who can lose money longer than you can earn it. So we defined a category we are already the only credible occupant of: Resident Voice AI. The word does double duty — the agent is resident on your infrastructure, and in a hospital, the resident is the one who is always there. The agent that is always there, on your floor, with your data. We didn't invent the need. Hospitals miss calls all day because the front desk is one human deep, and their compliance rules won't let the fix live in someone else's cloud. We built the fix that fits the rule. The category follows the customer. Next instalment? The naming story — why a Sanskrit prefix, an open vowel and a V travelled warm → daring → solid in three syllables.
