ABSTRACT:
A system for developing dialog systems estimates the speech recognition accuracy achievable when using a dialog system, and the number of example input phrases required to achieve a desired speech recognition accuracy. The maximum achievable speech recognition accuracy is also predicted. The development system thereby allows a developer of a dialog system to determine how and whether to continue development of the dialog system. The development system includes a grammatical inference engine for generating a grammar for the dialog system on the basis of example input phrases, and an in-grammar speech recognition accuracy estimator for generating the estimate of speech recognition accuracy on the basis of probabilities of confusing phonemes of input phrases with phonemes of the grammar.
