2. The method of claim 1 wherein generating the timing file comprises: storing the elapsed time information for a recognized portion of text in the timing file if the recognized portion of text matches the corresponding expected portion of text; and storing the determined elapsed time information for recognized words having the same number of syllables or phonemes and the different number of words into the timing file when the recognized portion of text does not match the corresponding expected portion of text.
1. A computer implemented method comprising: applying speech recognition by one or more computer systems to an audio recording to generate a text version of recognized portions of text; determining by the one or more computer systems an elapsed time period from a reference time in the audio recording to each portion of text in the recognized portions of text; comparing by the one or more computer systems a recognized portion of text to an expected portion of text; determining by the one or more computer systems a number of syllables or phonemes in a sequence of expected words that are part of the expected portion of text; determining by the one or more computer systems a corresponding recognized portion comprising a sequence of recognized words, the sequence of expected words and sequence of recognized words having a same number of syllables or phonemes and a different number of words; determining by the one or more computer systems an elapsed time for the corresponding recognized portion; storing the determined elapsed time in a timing file that is stored on a computer-readable storage device, the timing file further comprising the elapsed time information for each expected portion of text; receiving from a user an indication of a user-selected portion of text; determining by the one or more computers an elapsed time in the audio recording by referencing the timing file associated with the user-selected portion of text; and providing an audible output corresponding to the audio in the audio recording at the determined elapsed time in the audio recording.
