There are now nine Voice options in the ChatGPT app. Each one has a different tone, style and… “personality.” (I went with Sol) It also has something called “speech-to-speech capabilities.” This means that it can pick up on tone changes, “allowing for a more natural, human-like conversation and faster interrupting.”
I’m not sure about “Advanced Voice.” If you want it to sound more like yourself then you can ask it to adopt a specific accent. It won’t be able to directly mimic your voice but it can sound like it’s from your neck of the woods. I don’t think so. If I want to hear the lilting sounds of Southeast Missouri, I’ll talk to Barb.
