I interact with ChatGPT by voice pretty often, they have the best speech recognition I’ve ever seen. I can switch between languages (English, French, German) mid-sentence, think aloud, stop mid sentence, the correct what I just said, use highly technical terms (even describe code), I don’t even double check anymore because it’s almost always transcribed correctly.
They can ~easily evolve the product to a more generalized conversation UX instead of just a text based chat.
