First here were my settings:
Under Settings > Accessibility > Narration > Text-To-Speech
Speech-to-Text option is On
Settings > Online > Voice Chat
Voice Chat is On
Voice Chat Method is Voice Activated
Mute Microphone is Off
With that out of the way, even though I’m completely silent, the Speech-To-Text A.I. (or w/e) is entering random words when units are speaking. Funnily, when using English it interprets “I’m ya worka” into “worker”.
