Abstract:
1. A computer-implemented method of generating a transcript of a speech sample response to a test question, comprising: accessing content of a test question using a processing system; acquiring supplemental data content based on the content of the test question using the processing system; receiving a speech sample that is responding to the test question at an automatic speech recognizer having an adaptive language model; and generating a transcript of the speech sample with the automatic speech recognizer using the adaptive language model; the automatic speech recognizer applying the adaptive language model adapted to the test question based on the acquired supplemental data content to improve recognition capabilities of the automatic speech recognizer using the processing system, wherein the adaptive language model is adapted to the test question based on the supplemental data content including (i) prior automated speech recognition data related to the test question based on speech recognition without the adaptive language model, (ii) data related to the test question retrieved using the test question as a query, and (iii) human-generated transcript data related to the test question, the language model comprising a weighted index of words, one or more of the weights being determined by training the language model relative to a plurality of training items.
