Of the Voice Assistants I have used, to ask questions on things I don’t know about, I have found ChatGPT Voice by far the best. It is quick to understand my accent, super fast in its response, cohesive when referring over to previous responses in the current chat. I have always ended up knowing something and with a smile!
If I were to be really nit-picky, I would only say that initial “Connecting” UX could be avoided and it could start listening from the moment I tap the microphone icon!
