Why enterprise CX lands here.
#1 ranked voice on a cascade you can audit. Telephony, on-prem, BAA on day one.
Enterprise CX already runs on it
The voice layer behind enterprise CX platforms.
Contact-center platforms and in-house support orgs ship on the same cascade pipeline that powers consumer voice apps at scale.

Cascade gives you control
Interrupt control, model choice, layer-by-layer debuggability.
Pick your STT, your LLM, and your TTS. Swap any layer, audit every call. Unified speech-to-speech hides all of that in a black box.

Interrupt-aware by default
Agents that don't talk over your callers.
When a caller jumps in, the agent drops mid-word and listens. Fewer repeat phrases, shorter handle times, CSAT that holds under stress.

FAQ
Enterprise CX platforms, call-center automation, in-house support orgs, and agent platforms. Regulated verticals (healthcare, finance) run on-prem with HIPAA BAA.

Yes. TTS and STT both deploy on-premise on H100, A100, H200, B200, B300. Healthcare and government partners run fully isolated on-prem. Enterprise CX platforms run on-prem with compliance review. Contact sales for on-prem evaluation.
Cascade means STT → Router → TTS as swappable layers in a single persistent session. Unified S2S models (like OpenAI Realtime with gpt-4o-realtime) bundle the pipeline. Enterprise CX needs layer-by-layer interrupt handling, model choice per intent, and auditable per-layer logs. Cascade gives you all three; S2S hides them.
Any LLM through the Router: GPT, Claude, Gemini, Llama, Mistral, hundreds more. Switch by intent (escalation to a premium model; FAQ to a fast cheap model). CEL conditional routing handles this natively.
SOC 2 Type II certified. GDPR compliant. Zero data retention on TTS by default. HIPAA BAA signed with healthcare partners. On-premise + air-gapped deployment for sovereignty requirements.
The first audio lands in under a second from the moment the caller stops speaking. The voice layer alone hits under 200ms; the rest is your chosen model thinking. Route simple intents to a fast model, save the heavy reasoning for when it matters.
TTS is GA. Router and STT are in research preview. Realtime API is in research preview (WebSocket GA, WebRTC and SIP in early access). On-premise deployment is enterprise-available today.
