1. A method for automatically censoring audio data, comprising the steps of: (a) automatically processing the audio data to detect any undesired speech that may be included therein, by comparison to undesired speech data; and (b) for each occurrence of undesired speech that is automatically detected, altering the undesired speech detected in the audio data, producing censored audio data in which the undesired speech is substantially no longer perceivable by a listening audience.
