Abstract
A speech recognition system receives an audio signal and detects various features of the audio signal. For example, the system classifies the audio signal into speech and non-speech portions, genders of speakers corresponding to the speech portions, and channel bandwidths used by the speakers. The system detects speaker turns based on changes in the speakers and assigns labels to the speaker turns. The system verifies the genders of the speakers and the channel bandwidths used by the speakers and identifies one or more languages associated with the audio signal. The system recognizes the speech portions of the audio signal based on the various features of the audio signal.
