Hi
This occurs on my Samsung S24 FE.
Since last week, I think, when I choose the assistant, press the microphone and start to speak , the recorded words are trippled into a chaotic text.

Additional info.
Speech to text doesn't seem to work in Google in Samsung Internet. Microphone permitted.
Speech to text do work in Google in Chrome Web browser. Microphone permitted.
Kagi app, Microphone permitted.
My spoken words turned into readable text, as it did earlier.
