The conversation cycle

Each exchange follows a cycle:

  1. You speak — your voice is captured by the microphone
  2. Speech recognition — your words are converted to text
  3. AI thinking — the tutor processes what you said and formulates a response
  4. Speech synthesis — the tutor's response is converted to speech
  5. You hear — the tutor speaks through your device or headphones

This cycle happens in seconds, creating a natural back-and-forth conversation.

Barge-in (interrupting the tutor)

When using headphones, you can interrupt the tutor at any time by speaking. This is called barge-in. The tutor stops, listens to what you say, and responds.

On loudspeaker, barge-in is disabled because the microphone picks up the tutor's own voice. Headphones are strongly recommended for the best conversational experience.

Text transcript

The transcript is hidden by default — Epivo is voice-first. You can turn text on whenever you want it: switch on Show text in Preferences, switch to typing, or mute the tutor. With text on it helps you follow along, especially for:

  • New vocabulary words you might not catch by ear
  • Complex explanations that benefit from reading and listening
  • Language learning, where seeing the written form reinforces the spoken form
