Hi guys! I’m trying to see if there’s alternatives in TTS for the (admittedly) great one Google provides. I’m using Graphene, and so that’s not an option I’d like to go around.

Alternatively on the FOSS field, I believe have RHVoice, which I have installed, and eSpeak, which was last updated in 2022 and is not compatible with my Pixel 7 64bit-only phone. So…RHVoice has the problem of having their voices a bit robotic, but more probrematic is that they’re VERY muted. On max volume, they’re not all that loud, and I ride a motorbike. They’re pretty useless, most of the times I can’t hear the directions on my headset. Do you guys know any alternative TTS engine I could be using? I’ve heard the demo sample from the aiyu-ayaan tts-engine and it sounded great, but no idea how can I compile/install it as an Android TTS engine available for other apps to use, just like RHVoice.

Alternatively, are there any other apps/engines you’d recommend?

Thank you!
