"In today’s business world, a large part of communication between people happens over voice. Therefore, even if that exchange of information is recorded, it would take the same amount of time to go through it all to understand it. The text is simpler in this respect. It is easier to analyze, and interpret. There are numerous applications in enterprise and healthcare sectors where speech recognition is vital in transcribing."
