Voice Mode
Voice Mode allows end users to interact with your AI assistant using speech. Users can speak their questions and receive spoken responses. The assistant uses the same knowledge base and configuration as text chat.
What is Voice Mode
Voice Mode transforms your agent into a hands-free conversation experience. Users tap the microphone, ask their question aloud, and receive a spoken reply.
Flow:
Speech → Transcription → Knowledge-based answer → Natural voice reply
Component | What It Does |
|---|---|
Microphone button | Starts or ends a voice conversation in the chat widget |
Voice overlay | Full-screen style view showing Listening → Processing → Speaking |
Transcript | Displays what the user said as text |
Spoken response | Plays the assistant’s reply aloud and shows it as text |
