binary classifier for speech

This program has two options: 1- to read audio signals and classify the signals into class A and class B. Class A is native speakers, and class B is non-native speakers. We need to manually classify the signals (training examples), then the system has to read and classify automatically. 2- Another classifier which we have to find the features and add those features to the classifier to classify the signal into native and non-native according to the features.
