- Notes:
  > Audio quality has as much influence on the final result as the source portrait. Record in a quiet place, keep the speaker at a consistent distance from the microphone, and remove obvious background noise before uploading. Clear pronunciation, moderate pacing, and natural pauses help the generated mouth movement feel more believable.
  > 
  > It is also useful to match the speaker’s delivery to the image. A calm portrait is better suited to a measured explanation than an excited sales pitch, while a lively character image can support more expressive delivery. When the audio contains several speakers, changing tone or very fast dialogue, split the material into manageable sections so each segment can be checked independently.
  > 
  > Before generating, listen to the full track with headphones. Fix clipped words, long silences, abrupt volume changes, and unwanted filler sounds first. Clean source audio produces a more useful result than trying to repair every issue after video generation.
