Amazon Transcribe is an automatic speech recognition (ASR) service that makes it easy for you to add a speech-to-text capability to your applications. You can use Amazon Transcribe to create text transcripts of audio and video files. Coming soon, Amazon Transcribe will support a feature called channel synthesis to better handle audio where each speaker records on a different channel. For example, a stereo track with the interviewer is stored in the left and the interviewee on the right.
