Text to Speech (TTS) Intents
WearHF provides a TTS (text to speech) service which allows your app to speak text out to the user using the HMT’s speaker. This provides an alternate way to provide information other than using the screen.
Send a string to the TTS service
If you want WearHF to read out a string of text using TTS, use the following intent.
