According to # Privacy & Controls on https://help.openai.com/en/articles/8400625-voice-chat-faq#h_0173d3c9e3, we can only share audio but can’t download it (it’s stored somewhere where getting access to it is not part of the documentation).
My questions is:
Are we able to export/download our conversations using voice as audio file/mp3?
Should this be a great exchange of value if we also allow OpenAI to listen to our voices and learn from it?
Good question, I’m wondering the same thing. 
Hi!
That’s a nice idea.
It’s currently not possible though. Audio conversations are stored as text conversations in your chat history. And that can be downloaded via data export.
I know there is a chrome extension to download chatgpt response as an audio. That is AudioTTS. Have you try?
It works.
Can you give an option to change the format? eg. mp3?
Yes AudioTTS support mp3, AAC and opus. With this chrome extension you will be able to export, save and download the chatgpt response as an audio
