Oculus Quest Speech to Text API/SDKs that work

I am an amateur Unity programmer currently teaching myself how to work with speech-to-text API. Though I have had no difficulty implementing the various SDK/APIs available (Google Cloud Speech-to-Text API, Watson, Light Buzz, etc.) to work on the Rift, Windows, iOS, I can't figure out how to implement it on the Oculus Quest.

The furthest I have gotten on the Quest is with the Google API, but the Quest fails when it attempts to SpeechClient.Create(); Any input would be greatly appreciated or recommendations for other ways of implementing Speech Recognition on the Quest
