Voice Test

Voice Test is the fastest way to talk to an agent — a browser mic session with no phone number required. Use it to iterate on prompts, providers, and tools before you go live on telephony.

Start a test call

Open your agent in the dashboard and click Voice Test, or hit the mic. The browser streams your audio to the agent over a WebSocket and plays the agent's speech back in real time.

What you can see

• Live transcript — each turn as you and the agent speak, with per-turn timing.
• Latency breakdown — ASR, LLM first-token, and TTS time-to-first-byte for every turn.
• Tool calls — when the agent invokes a custom tool and what it returned.

Tips

• Test barge-in: start speaking while the agent talks — it should stop and listen.
• Watch LLM TTFB — it dominates perceived latency; switch providers/models here to compare.
• Everything you test carries over to telephony unchanged; the only difference is the transport.
