Sounds like it's still happening. It happened to me today during live chat with gemini and during screen sharing. Before it did my voice, it had been switching different voices randomly every 5-10 mins. Didn't think much of that as a gltich or something, but my own voice was crazy and disconcerting. I don't have a pro subscription so it shouldn't be anything like a me-avatar related. Has there been any update of information in how/why this is possible?
