15. The method of claim 12 , further comprising generating a word lattice based on recognition processing of the speech model and the wave data, the word lattice employed to compute the word confidence score.
12. A computer-implemented method of error checking, comprising: computing duration probability data by forcing alignment of a speech model and a corpus of transcription data and wave data; computing a confidence score based on recognition processing; detecting errors based on the duration probability data and the confidence score; and retraining the speech model based on removal of the errors from the corpus.
