dc.description.abstract | In this thesis, the development of an algorithm and system that is able to recognize gender and races by using the speech frequency spectrum is presented. Some of the features extracted are the formant frequency and fundamental frequency of speech
signals. The formant frequencies are obtained by finding a set of predictor coefficient that minimizes the mean square error over a short segment of speech waveform. Whereas the fundamental frequency is estimated by finding a peak in the auto-correlation function with a corresponding delay. Results obtained using this approach to identify the gender by using formant frequency and fundamental frequency has proven to be practically applicable. The Back-Propagation Neural Network has been chosen for the classification purposes. These features will be fed into the neural network for training until it is able to
outputs the appropriate gender and races. The speech recognition application is
implemented using the Digital Signal Processor (DSP). The well trained network
parameters were applied in the DSP by the new architecture support features that
facilitate the development of efficient high level languages. Hence, C code was chosen to
read a set of input features, as the weights are being adjusted and weights sum output
from input features, the corresponding results are finally displayed on the Liquid Crystal Display (LCD) through DSP. | en_US |
