1. A method of evaluating a speech sample using a computer, the method comprising:
- receiving training data comprising samples of speech;
storing the training data along with identification of speech elements to which portions of the training data are related;
receiving a speech sample;
performing speech recognition on the speech sample to produce recognition results; and
evaluating the recognition results in view of the training data and the identification of the speech elements to which the portions of the training data are related, wherein;
performing speech recognition on the speech sample comprises identifying portions of the speech sample to which different speech elements correspond; and
evaluating the recognition results comprises comparing a portion of the speech sample identified as corresponding to a particular speech element to one or more portions of the training data identified as corresponding to the particular speech element.

Abstract
A speech sample is evaluated using a computer. Training data that include samples of speech are received and stored along with identification of speech elements to which portions of the training data are related. A speech sample is received and speech recognition is performed on the speech sample to produce recognition results. Finally, the recognition results are evaluated in view of the training data and the identification of the speech elements to which the portions of the training data are related. The technique may be used to perform tasks such as speech recognition, speaker identification, and language identification.

22. A computer program, residing on a computer readable medium, for a system comprising a processor and an input device, the computer program comprising instructions for evaluating a speech sample by causing the processor to perform the following operations:
-
receive training data comprising samples of speech; store the training data along with identification of speech elements to which portions of the training data are related; receive a speech sample; perform speech recognition on the speech sample to produce recognition results; and evaluate the recognition results in view of the training data and the identification of the speech elements to which the portions of the training data are related, wherein; analyzing the training data comprises identifying portions of the training data to which different speech elements correspond; performing speech recognition on the speech sample comprises identifying portions of the speech sample to which different speech elements correspond; and evaluating the recognition results comprises comparing a portion of the speech sample identified as corresponding to a particular speech element to one or more portions of the training data identified as corresponding to the particular speech element. - View Dependent Claims (24, 25, 26, 27)
