Voice engine
Chatley's live in-browser voice calls (the Talk to Assistant button) are powered by Chatley's real-time voice engine. You don't need any extra accounts or keys — Chatley handles it for you. This page explains how it works and what to expect.
How it works
- When you start a browser call, Chatley requests a short-lived session token from its own server for the specific agent (or workflow) you're testing.
- The browser uses that token to open a live audio session with the voice engine using your microphone.
- Sensitive credentials never touch the browser — tokens are issued server-side, per session, so nothing sensitive is exposed on the client.
What you need
- Microphone access. Your browser will ask for permission the first time — allow it, or the call can't start.
- You must be signed in. Tokens are tied to your authenticated account and workspace.
- A modern browser with a stable internet connection (the call has a short connect timeout and will retry briefly under load).
Demo mode
If live voice isn't configured in an environment, the engine runs in Demo Mode: calls are simulated, you'll see an amber Demo Mode badge, and no real audio session is placed. The flow behaves the same so you can still click through it.
Concurrent-call limits
Your plan allows a certain number of simultaneous calls. If you're at the limit, a new call waits in queue and starts automatically when a slot frees up. If the voice service is momentarily busy, Chatley retries the start for you before giving up.
Troubleshooting
| Problem | What to check |
|---|---|
| "Voice Assistant Unavailable" | Voice isn't available for this agent yet, or no agent/workflow is selected. Reopen the agent. |
| No audio | Confirm the browser has microphone permission and the right input device. |
| Call won't start / times out | Check your connection and retry; the connect timeout is short by design. |
| "Voice service is busy" | The engine hit a temporary rate limit — wait a few seconds and try again. |
| Stuck in demo/simulated calls | The environment is in Demo Mode; live voice isn't configured there. |
