FEATURES · A TOUR YOU CAN SKIP THROUGH

Nine chapters.
Everything TransVoix does.

A walk through every shippable capability — voice, language, trust, integration. Read top-to-bottom for the full tour, or jump straight to what you came for using the rail on the left.

LAYER · VOICE

Speak in theirvoice.

The agent's voice is cloned once at enrollment and used in both directions — outbound and inbound, in either language. The customer hears the agent. The agent hears the customer. Neither hears a generic TTS.

CH 01

Bidirectional
voice clone.

One enrollment, both directions, both languages. Refreshed quarterly or on demand. Prosody, accent, and micro-pauses preserved end-to-end.

CH 02

Sub-second
time-to-speak.

~740 ms p50. Slow enough that the customer doesn't get whiplash, fast enough that they don't start repeating themselves.

p50 is the benchmarked end-to-end figure. p95 / p99 are illustrative tail shapes — not measured timings.
LAYER · LANGUAGE

Languages thatswitch mid-call.

6 languages live across 30 bidirectional pairs, 9 more in beta, 13 on the roadmap. The customer never picks a menu — we detect, switch, and keep going. If the call rotates between three languages in five minutes, the agent stays in their native language and the platform handles the rest.

CH 03

Auto-detect &
mid-call switch.

No IVR menus, no language prompts. The customer changes their mind, or another household member takes the phone. The platform tracks it.

Glossary you
control.

Each tenant owns a termbase: locked translations, pronunciations, dialect variants. Versioned, signed, A/B-able per queue. The model defers to your terms before its own.

LAYER · TRUST

Audit-ready bydefault.

The hard part of voice AI in regulated industries isn't the voice — it's the audit. Every utterance is signed, every correction is append-only, every minute is exportable.

CH 05

Corrections that
append, never edit.

A mistranslation gets a signed correction utterance threaded into the audit log. The original is preserved. Reviewers see both. Regulators see both.

One C2PA manifest per call. Cryptographically signed. Verifiable without our cooperation. The audit answer to 'where did this audio come from' lives in the file itself.

CH 07

PII redaction by
zone, not globally.

Different queues have different rules. Healthcare redacts SSN/DOB/MRN before storage. Sales redacts only credit cards on export. Both honoured.

LAYER · INTEGRATION

Plugs into thestack you have.

Generic by design. Anything that speaks SIP, WebRTC, or HTTPS connects in days, not quarters. We don't ship a contact-centre suite — we slot into the one you bought.

CH 08

Standard
protocols.

SIP, WebRTC, PSTN, REST, webhook, gRPC. If your contact-centre platform speaks any of them — and they all do — we connect in days.

SUPPORTED PROTOCOLS ● ALL STANDARD
SIP
Trunk to any standard PBX
WebRTC
Browser-native, zero install
PSTN
Carrier handoff where required
REST
Outbound dial, batch ops
Webhook
Inbound events, call lifecycle
gRPC
Streaming audio, low-latency
→ if it speaks any of these, we connect in <3 days
CH 09

Write-back that
lands clean.

Call summary, glossary hits, corrections, redactions, manifest URL, outcome — written back to the customer record as structured fields. Your reps don't transcribe; your analysts get clean data.

FINALE · COMPARE

Against the
two real alternatives.

The other paths most teams weigh: a human interpreter on the line, or a generic MT-plus-TTS layer cobbled together. We optimise for the calls where the voice and the audit trail both matter.

FAQ

Things buyers ask.

Does TransVoix replace our human interpreters? +
No. Most teams pair us: TransVoix handles high-volume routine calls (eligibility, scheduling, follow-up) and routes complex cases — clinical consent, sentencing, anything legally consequential — to the human queue. The balance shifts toward automation as a team builds confidence over the first quarter.
How good is the cloned voice? +
Translation quality benchmarks at 4.72 out of 5 across our 30 production language pairs. We clone prosody and accent, not tone-of-the-day; if an agent has a cold, the clone has the cold. We refresh enrollment quarterly or on agent request.
What happens if the model mistranslates something critical? +
Append-only correction. The supervisor (or the agent themselves, mid-call) issues a corrected utterance which is C2PA-signed and threaded into the transcript with timestamp and signer ID. The original is never deleted.
Can we control terminology — drug names, plan codes, internal jargon? +
Yes. Each tenant has a glossary with locked translations and pronunciations. Glossary entries are versioned and signed; you can A/B them per queue.
Where does the audio actually live? +
US data processing today (us-east-1). EU residency available ONLY as an Enterprise-tier contractual term (not self-serve, not general availability). Audio is encrypted at rest (AES-256); Per-tenant KMS available on Enterprise. We do not train on call content.
How long does setup take? +
Free. We align scope on a discovery call first, then you run 500 minutes or 30 days (whichever comes first) across 3–5 agents — no fee, no credit card, no commitment. Day 0: kickoff + voice enrollment. Day 1–7: integration with telephony and CRM/EHR. Day 8–30: shadow-mode, then live calls.
