Voice Agents

A voice agent answers a phone call, holds a conversation, calls your code when it needs to do something, and hands off to a person when it should. It is the same agent object as a messaging agent, with a voice block on it.

Zavu runs the whole pipeline: speech recognition, the agent's model, speech synthesis, and interruption handling. You supply the prompt and the skills.

One thing to know before anything else: voice is the channel where tools actually run. On plain text the model is not offered tools at all (see ai-agent). If your agent has to do something, voice and flows are where that works today.
