Questions and fixes
It can’t use my microphone
Your browser asks for permission the first time. If you pressed Block, click the padlock or settings icon at the left of the address bar, set Microphone to Allow and reload the page. Also check your device’s privacy settings allow your browser to use the microphone, and close other apps (such as Teams or Zoom) that might be using it.
The letters come out wrong when I tap
Make dashes about three times as long as dots, and pause a little longer between letters. Adapt to my speed helps it follow you.
