Question

MetaVoice SDK

I’m working on a VR application where I’m using the XR Interaction Toolkit for interactions. I have a scene where, on a button click, text is revealed and AI-generated voice is played using Meta Audio SDK TTS (Wit.ai).

Everything works perfectly in Play mode — I can hear the text-to-speech audio without any issues.
However, after I build the application and run it in the headset, the audio does not play at all.

I need help understanding why this is happening and how I can fix it.

Hey there Hem8!

I understand you're having trouble getting TTS to work in your build, and I get how irritating that can be. Regarding TTS in the Voice SDK, I'm not sure if you've seen our documentation yet but we have some great resources that should hopefully put you on the right track. That documentation also covers how to script the events and trigger the playback, which you'll need to load and play the text. I can also link the overview to the Voice SDK, which provides a lot more detail on that SDK's functionality.

I hope you were able to find some of this useful, and if you're still running into trouble after reading those, please feel free to let me know and we can troubleshoot further!
