Open the original- What it measures
- Conventional learning is the one Gboard learning method that sends audio to Google, and you choose it when you talk to Gboard. The snippets are the audio you agree to donate, and the 15-second limit comes from the same paragraph.
- What it does not show
- The page says snippets may be up to 25 seconds if there is silence or unrecognized audio, so the 15-second figure is the usual maximum, not an absolute one. The page does not say whether the opt-in is on by default on every device.
