We are building an app that heavily use TTS to generate speech from database content to our users. The overall quality of the sound is "ok" but not "great". We are using Acapela Voice Services. We tested quite a bit of providers :
But the best so far was Acapela.
But when I use the Google Maps app on android though, the quality of the voice is way better the what I can hope for with Acapela. Is this "service" available somewhere in the SDK ? Is there a component I can get somewhere ? What am I missing ?
