UN style audio localization
When the speech volume of the person speaking in your video is turned down, and the voice actor
speaking in the target language cuts over it at a higher volume.
Remove original audio
You can choose to remove the original audio and have the target voice actors localized speech synced with the speaker’s lips and mouth movements.
One option is the use of subtitles at the bottom of the video. Simple subtitles in place of audio dubbing can be used in cases where only minimal localization is needed.
