N2 - A multilayer perceptron trained with the backpropagation procedure is used to detect the fundamental frequency (F0), or pitch, of a speech signal. The model does not require preprocessing of the signal and has good discriminatory capabilities. Preliminary results suggest that a multilayer perceptron can be trained to extract F0 as well as the formants. In the preliminary experiments, the detection rate of F0 was 100% for different numbers of hidden units. As the number of hidden units was increased, the generalization capabilities of the neural net decreased.
