In the workspace
Start a live voice call from the chat composer. Speak naturally; the agent responds in real time and can still use its tools, knowledge, and sandbox mid-conversation.
Voice
Your agent can talk. Voice turns any agent into a real-time conversational partner — you speak, the agent listens, thinks, and replies out loud, streaming as it goes.
Where voice works
Section titled “Where voice works”Over the phone
Connect a phone number (via Twilio) so customers can call your agent directly. Phone numbers require a Business plan or above.
Choosing a voice
Section titled “Choosing a voice”Manage voices in Console → Voices, then assign one to an agent. Three voice types are available:
| Type | What it is | Best for |
|---|---|---|
| Preset | A built-in, ready-to-use voice | Getting started quickly |
| Designed | A voice generated from a text description (e.g. “warm, calm, mid-range female”) | Matching a brand persona without a recording |
| Cloned | A voice created from a short audio sample you provide | Reproducing a specific person’s voice |
Setting up voice on an agent
Section titled “Setting up voice on an agent”- Go to Console → Voices and pick a preset, design a new voice, or clone one from a sample.
- Open your agent and assign the voice in its settings.
- Open the agent in the workspace and start a voice call from the composer — or, for phone access, connect a number on a Business plan.
How it sounds natural
Section titled “How it sounds natural”- Streaming responses — the agent starts speaking as soon as it has something to say, rather than waiting for the full answer.
- Barge-in — you can interrupt the agent mid-sentence and it will stop and listen.
- Tools mid-call — the agent can search, query knowledge, or run sandbox actions while you’re talking, then narrate the result.
- Keep instructions conversational — voice agents read instructions the same way chat agents do, but spoken replies work best when they’re concise.
- For customer-facing phone agents, define how to handle silence, escalation, and “I didn’t catch that” cases in the instructions.
- Voice is credit-intensive (30 credits/min in the browser, 54 credits/min over a phone number) — set per-agent credit limits if you expose it to external callers. See Pricing & Credits.
