Creepy interactions in Advances voice mode: Heard my own voice

I tasked ChatGPT through the advanced voice mode to quiz me on various topics. In the film category I was asked “Who directed short pause PSYCHO”. The word “psycho” however, was not in the regular female voice like the other words in the sentence: The word was said by MY OWN voice! It sounded exactly like a voice recording of myself. It was such an eerie moment.

Is open AI secretly using all our audio for training voice synthesis of the individual users voices?!
