An application can control speech output using the following calls:
TextToSpeechResume
TextToSpeechReset
These calls pause the audio output, resume output after pausing, and reset the text-to-speech system.
A reset discards all queued text and stops and discards all queued audio. If the application has called
TextToSpeechOpenInMemory to store speech samples in memory, a reset causes all buffers to be returned to the application.
