Can transformer be better than RNN for online speech recognition?

Does transformer have the potential to replace RNN end-to-end models for speech recognition for online speech recognition? This mainly depends on accuracy/latency and deploy cost, not training cost. Can transformer support low latency online use…

Open-source vocal cloning (speech-to-speech neural style transfer)

I want to program and train a voice cloner, in part to learn about this area of AI, and in part to use as a prototype of audio for testing and getting feedback from early adopters before recording in a studio with voice actors. For the prototype, I…
