ProtoPie Voice Prototyping Not Working

Share
Workaround available Windows, macOS, iOS, Android Updated November 14, 2026How we research

Quick answer

Voice commands need a Listen response; text-to-speech needs a Speak response with correct text, and support depends on where you run the prototype.

Most likely fix: Speech-to-text

How to fix it

Try these in order — the most common fix is first.

  1. 1. Speech-to-text

    1. Add a Listen response, voice is not detected by default
    2. Stay close to the microphone, reduce noise and speak clearly
    3. Use Studio preview, Player, or Cloud in Google Chrome on desktop or Android
    Did this fix it?

  2. 2. Text-to-speech

    1. Use a Speak response
    2. Check the text, typed or from a formula, is correct
    3. Supported in Studio preview and Player
    Did this fix it?
