Instead I use igo Nextgen for only three years, before AVIC and now ISRAEL. With AVIC I used the Nuance Vocalizer Expressive, and now with Israel the internal tts_nua_ve1, less cumbersome and more practical.

What you call Google TTS is nothing more than the engine for the Vocalizer, has nothing to do with the voice of Google, you can call it as you like, even Apple TTS, but nothing changes, remains an engine for Vocalizers .....
