I dont like the fact that this voices sounded the same from january 2015. This is absolute noncence that you need an api key for wavenet voices and then you cannot even use it for screen readers. Ask money if for wavenet voices without letting us do all the work to get api keys and then we cant even use it for screen readers and everyone will agree or what? 0 stars I wont use this noncence until you add wavenet voices. I recommend that you stop these api key nonsence and let us pay wavenet voice
