This API automatically clone the voice from the input audio, and create new audio using the same voice.
Make sure to properly select source_lang, target_lang, and num_speakers.
If you want to further change the lip motion of your input video, you will need to use api/v1/video/generate by providing the audio from the dubbing result.
