Simply to see how easy it really is to have my own or the kids voice do some funny things. Speaking. I would like to feedback some kind engine with mp3 files (voice audio) and train it to speak in that voice. I was hoping i could set it up on my own machine and not rely on a cloud provider. I have only tried the I OpenAI speak to text api, and that was easy setting up locally. Thanks
