GPT-5.2

For me the last remaining killer feature of ChatGPT is the quality of the voice chat. Do any of the competitors have something like that?

gemini live is a thing - never tried chaptgpt, are they not similar?

Not for my use case. I can open it up, and in restored classical Latin pronunciation say "Hi, my name is X, how are you?" and it will respond (also in Latin) "Hello X, I am well, thanks for asking. I hope you are doing great." Its pronunciation is not great, but intelligible. In the written transcript, it butchers what I say, but its responses look good, although sans macrons indicating phonemic vowel length.

Gemini responds in what I think is Spanish, or perhaps Portuguese.

However I can hand an 8 minute long 48k mono mp3 of a nuanced Latin speaker who nasalizes his vowels, and makes regular use of elision to Gemini-3-pro-preview and it will produce an accurate macronized Latin transcription. It's pretty mind blowing.
