Noise-dependent Gaussian mixture classifiers for robust rejection decision.

Noise-dependent Gaussian mixture classifiers for robust rejection decision.

Speech or speaker recognizers need to make a decision on either accepting or rejecting a recognized item, based on some measurement (e.g., likelihood) associated to the item. Distribution-based classification can be used to make the decision. In practical applications, the background noise level may...
