# Audio Matching

This section describes the actions that you can use to train audio matching.

NOTE: Apart from ListAudioMatchDatabases and ListAudioMatchClips, all of these actions are administrative actions. Administrative actions can be sent only by users who belong to an authorization role that allows the `Admin` standard role, or which enables the action explicitly.
