ABSTRACT:
A recording is indexed by keywords. In order to perform the indexing, an audio portion of the recording is transcribed to produce text in a text file. A time stamp is associated with each word in the text. Each time stamp indicates a time in the recording at which occurs an associated word. Once a recording has been indexed, the recording may be searched along with other recordings. For example, in response to a user choosing a keyword, a text file for each recording is searched for occurrences of the keyword. At the conclusion of the search, each recording which includes an occurrence of the keyword is listed. When a user selects a first recording and a particular occurrence of the keyword, the first recording is played starting slightly before a time corresponding to a first time stamp associated with the particular occurrence of the keyword in the first recording. In response to control sequences, prior and next occurrences of the keyword can be observed in one or multiple recordings.
