Audio transcription is nothing but the process of converting voice to text. It can be performed quite comfortably with the help of a transcriptionist. The audio transcription is not only meant for serving as a record, but it is quite useful for those who possess hearing disabilities as they can't hear the speech or music in a movie. There are transcription companies that are expertise in building captions for movies and songs as well.
