I made a voice simulator of my own voice (https://locserendipity.com/sim/voice.html https://locserendipity.com/sim/voice.html) by recording individual phonemes. My goal was to create the smallest possible phonemes that can be concatenated into a wav file. Ultimately, I want to be able to export a wav file or mp3 file as base64 text enabling the largest amount of voice data to be stored on a CD. Does anyone have further advice on how to achieve this?
