* @brief Requests to send TTS streaming data, asynchronously.
* @details Using this function, the developer can request text to speech to the framework.
* When the developer requests the TTS with @a language, VC engine will send PCM data which is synthesized using VC engine's own persona.
* and then it will be spoken in VC manager. If @a to_vc_manager is false, you will receive PCM data through the vc_tts_streaming_cb() callback function if it was set using vc_tts_set_streaming_cb().
* This function is executed asynchronously, so if there is an error while synthesizing, vc_error_cb() will be called.
