Patent No. 7437290
- 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, by performing the following steps; comparing words in the audio data against words comprising the undesired speech, to identify potential matches; dynamically varying a probability threshold dependent upon at least one criterion; and based upon a probability of a potential match and the probability threshold, determining whether any undesired speech is included in the audio data;
(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; and
(c) dynamically adjusting the probability threshold based upon a frequency with which undesired speech by a specific speaker is detected in the audio data, so that as the occurrences of undesired speech that are detected increase, the probability threshold is reduced.
