It sounds terrible and inhuman, but there is definitely some similarity to the target voices. It's much easier to detect the similarity when you compare the different voices to each other saying the same phrase, instead of just listening to one in isolation<p>Alan Rickman seems clearer than the others.
I have been working on a side project that attempts to clone human voices. www.voiceclonr.com presents the voices of Alan Rickman, Carl Sagan and Robin Williams. Appreciate if you could give it a try and leave feedback.
Pretty cool. Rough and fuzzy around the edges, some of the usual speech synthesis cadence issues. Any insight into the techniques you're using to do this?
