Error shown in the video (ADB Logcat) when trying to play the TTS Text to Speech output on the Oculus Quest in the background:

Link to Android API TextToSpeech synthesizeToFile() which works with pico tts on the latest (Version 17 and up) of the Oculus Quest software.

Hope this technical programming tutorial is useful to anyone trying to get Text to Speech TTS working on their Oculus Quest.
