Comments
The application must call TextToSpeechOpenInMemory before calling TextToSpeechAddBuffer. The memory buffer is passed using the TTS_BUFFER_T structure. The user must allocate the structure and its associated elements (memory buffer, phoneme array and index mark array).
Click here to go to the Speech-to-Memory Mode section for more information on the TTS_BUFFER_T structure and its elements.
The text-to-speech system returns the buffer to the application when the memory buffer, phoneme array, or index mark array is full or when a TTS_FORCE flag was used in the TextToSpeechSpeak call.
