Set up a voice agent — WA.Expert Help

Setting up a voice agent is similar to a chat agent: you create it, choose how it sounds, and give it the knowledge and instructions to help callers.

Set it up

Create a new voice agent.

Choose the model that powers its understanding and replies.

Choose the voice it speaks in.

Write clear, specific instructions defining the agent's role — for example, "You are a friendly voice assistant who helps users with support queries." Use simple, direct sentences. Click Optimize Instructions to have the platform automatically rewrite your prompt into a more AI-friendly format.

Set the Greeting — the exact welcome message spoken when a call starts.

Set the Silence Timeout: the number of seconds of no conversation before the call disconnects automatically.

Set the Off-Topic Question Limit: how many unrelated questions the agent will answer before ending the call.

Test the call experience before going live.

Why these settings matter

Clear instructions, a well-set greeting, silence timeout, and off-topic limit together keep the agent professional, focused, and natural — and prevent calls from running indefinitely on dead air or unrelated tangents.

Pick a fitting voice

The voice sets the tone of every call. Choose one that matches your brand, then test a real call to hear how it lands.
