Talk to it first
No recordings on this page — a real demo agent lives in the Voice Agent tab of the homepage studio. Press the button, ask anything, and it listens, thinks and answers in voice. The latency and tone you hear is what your own site would get.
Here is how it opens:
Beyond a greeting, it has to finish the job. This is what a confirmed booking sounds like:
How it works
Every exchange runs four stages, all in real time:
- Listen: speech recognition turns your words into text, with interruption support
- Think: an LLM answers using the system prompt, knowledge base and conversation history
- Speak: the reply is synthesized instantly in your chosen voice, 70+ languages
- Turn-taking: a dedicated model decides whether you've finished, avoiding talk-overs and dead air
End-to-end response stays under a second — conversational pacing close to a human's.
Three things that make it useful
- Knowledge base: upload product docs, FAQs and policies; the agent answers from your content, not imagination
- Tool calling: wire your APIs (order lookup, rescheduling, ticket creation) and the agent executes mid-conversation
- Your voice: reuse any voice from the library, including a cloned brand voice
Where it fits
| Scenario | Value |
|---|---|
| Website voice support | 24/7 front line, escalates complex cases |
| Phone reception / IVR upgrade | Twilio / SIP, replaces keypad menus |
| Language practice | Multilingual conversation with corrections |
| Interview & sales-pitch drills | Role-play, repeat as needed |
| Product tours | Like the homepage demo — explains your product for you |
Billing and onboarding
Agents bill per conversation minute, separate from voiceover credits. A custom build needs your knowledge files, the APIs to call, a chosen voice and an opening line. Open a ticket with your scenario; we build it and hand you an embed snippet or a phone number.
