Solutions for TTS and STT to build VR for Meta Quest...

Hello...

By following several tutorials for Convai AI, I arrived to implement a French pronunciation exercises. The idea is to get a TTS for any words or sentences to read as pronunciation model for students who want to practice their French pronunciation. The students can pronounce their French and their voice will be captured and send to Convai AI (convai player). The transcription will be posted in a text area. The students can see that their pronunciation is well done or not. After clicking on the button "Verification", if the two texts are equal, they will get a score. 

I bought Universal Native Offline TTS. It works well on windows VR and android phone VR, but it doesn't work on meta quest 2. I don't know why...
