Read all, or some portion of the synthesized audio buffer that was obtained from a
LVTTSClient::Synthesize call. Each successive invocation of this function reads the buffer at an offset that is after the last sample read in the previous call.
Function
- LV_TTS_RETURN_CODE GetSynthesizedAudioBuffer( void * buffer, int buffer_size_in_bytes, int * bytes_returned )
Parameters
buffer
Location of memory buffer where the synthesized audio samples need to be copied into.
buffer_size_in_bytes
Amount of memory allocated for buffer, number of bytes of synthesized audio samples to be read into buffer.
bytes_returned
The number of bytes of synthesized audio samples actually copied into buffer. This may be less than buffer_size_in_bytes if there is not sufficient data available.
Return Values
LV_SUCCESS
No errors; bytes_returned bytes of synthesized audio samples have been copied into buffer.
LV_FAILURE
The TTS client handle is invalid (either Initialize has not been called or Destroy has already been called); or buffer points to an invalid memory location; or results are not yet available.
LV_EXCEPTION
An exception occurred while processing the request.
