Fast transcription of speech

Abstract

A transcription tool assists a user in transcribing audio. The transcription tool includes an audio classification component that classifies an incoming audio stream based on whether portions of the audio stream contain speech data. The transcription tool plays the portions of the audio that contain speech data back to the user and skips the portions of the audio that do not contain speech data. Using a relatively simple command set, the user can control the transcription tool and annotate transcribed text.
