This worked right out of the box. I have this working in Home Assistant via EspHome. Reach out to me if you have questions or need consultation in that application.

Wled Audio Reactive

Worked right out of the box with no issues. Running it as a digital mic on the WLED audioreactive chain, it was detected in the console on the first run and has been going for 6 hrs now without any code modifications. I just ordered another.

Barely works-

Only works if I repeat exactly the person I am transcribing, into the phone myself-even then, despite being articulate I must make constant corrections.Try to get accurate transcribe of another person-talk slow clear English-you’ll spend half your time filling in mega blanks.
