New Speech-to-speech v3 · 620 ms median

Voice agents that
answer in under a second
in any language.

The real-time, multilingual voice-agent platform for teams who refuse to choose between latency, control and cost. Run it on your own metal, burst to our cloud, and ship one agent to a web widget, a phone line, or a robot in your lobby.

The platform

Everything a voice product needs.
Nothing you have to stitch together.

Agents, voices, tools and delivery in one runtime — so the thing you prototype on Tuesday is the same thing that answers ten thousand calls on Friday.

Agents that hold the thread

Barge-in, backchannel and turn-taking handled at the audio layer, not bolted on. Persistent memory, per-caller context and a deterministic state machine underneath the model, so an agent that books appointments never improvises a refund policy.

InterruptiblePersistent memoryGuardrailsHandoff to human

Voice design & instant cloning

Sculpt a voice from a text prompt, or clone one from thirty seconds of clean audio with consent capture built into the flow. Emotion, pacing and pronunciation dictionaries are per-agent, versioned and reversible.

Tools & MCP, natively

Point an agent at your MCP servers and it can read the CRM, move the booking and file the ticket mid-conversation — with every call traced and replayable.

Local first, cloud when it counts

Pin STT and TTS to the edge box in the building; burst reasoning to the cloud only when the task earns it. One config flag, no rewrite.

How it works

One turn, four hops,
six hundred milliseconds.

0 ms
Elapsed this turn
01 — Capture

Streaming STT

Audio is transcribed in 40 ms frames on the nearest node — the edge box on-prem, or the closest region. Language is detected per utterance, not per session.

90 ms
02 — Reason

LLM + tools

Partial transcripts stream straight into the model. Tool calls fire against your MCP servers while the caller is still finishing the sentence.

210 ms
03 — Speak

Neural TTS

First audio chunk leaves before the sentence is complete. Prosody follows intent, so a confirmation sounds different from an apology.

180 ms
04 — Deliver

Widget · phone · robot

The same stream lands wherever the agent lives — a browser, a PSTN leg, or the speaker array on a RoboPark unit two thousand miles away.
