Get raw audio of synthesized speech

How to get raw audio from text-to-speech synthesis.
Read time 1 minute
Last updated 8 months ago
You can synthesize speech into an audio buffer for your direct use rather than having it maintained internally by the Vivox SDK. 
vx_tts_speak_to_buffer
synthesizes the speech signal and returns it in the form of a 
vx_tts_utterance_t
 struct. This struct includes a pointer to the raw audio data, and metadata, such as buffer length and audio format properties.
vx_tts_utterance_t *utterance = NULL;vx_tts_status status = vx_tts_speak_to_buffer(managerId, voiceId, "Gimme the audio samples", &utterance);// If succeeds, utterance will contain the audio samples and the metadata for the synthesized speech.
Note
After you are finished using the text-to-speech (TTS) utterance, you must destroy it to avoid memory leaks.
vx_tts_status status = vx_tts_destroy_utterance(managerId, utterance);
