Voice Agents FAQ
Voice Agents is a platform for building real-time voice agents. You configure an agent with a prompt, a voice, knowledge and tools, test it in the browser, and deploy it to your website, your app, the API or a phone number.
Most teams make their first test call within minutes. Start from a template or a short description, try it in the browser, then publish it to the web, your app or a phone number.
Agents can use any of the 2,000,000+ voices in the Fish Audio library across 30+ languages, or a voice you clone yourself. Expressive mode, speaking speed and model tier are set per agent.
Yes. Upload PDFs, Markdown and URLs to a knowledge base for grounded answers, and connect tools that call your APIs during the conversation, such as refunds, bookings or CRM updates.
Add the website widget with two lines of HTML, build a custom experience with the React SDK, connect your own clients over WebRTC, or attach a phone number for inbound and outbound calls.
Yes. Agents can warm-transfer a call to your team and pass along the context, so the caller does not have to repeat themselves.
Every call comes with a recording, a transcript, per-turn latency and an automatic summary. Define success criteria and run tests before each release to catch regressions.
Speech recognition, the LLM and voice are billed together per minute, with add-ons such as premium LLMs and phone calls only when you use them. See the pricing page for current rates.
