Re: TTS suddenly sounds bizzare on Android phone
Yes, I get similar signals from other users too, and most blame me for the problem... Thank you for posting the sound samples, at least now I know what they are talking about. I really don't know why this happens and why Google won't fix it, despite being notified so many times about this problem. I observed something similar with their cloud voices, but less severe, so these are still usable. I did not observe the problem on my devices here, maybe it's only certain devices or Android versions where this problem occurs.
Whenever I can, I try to convince people to stop using the buggy Google Text-to-speech product and use something better, e.g. Vocalizer TTS voices that can be downloaded from Google Play store (free 1 week trial of each voice, purchase afterwards if you want). There are also many other good TTS engines and voices there, e.g. Acapela TTS, Cereproc voices, RHVoice (this one free, but lower quality) etc.
