# Audio Categorization

Media Server can categorize audio. Audio categorization segments and classifies audio into predefined categories such as "speech", "music", "noise", and "silence".

You can use audio categorization to inspect an audio file and decide whether to perform further processing. For example, when audio categorization reports that a file contains mostly speech, you might decide to run language identification and speech-to-text.

If you are processing recordings of telephone calls, you can use audio categorization to identify DTMF tones.
