Abstract
A description is presented of a speaker independent automatic speech recognition system for a small vocabulary, employing phonetically based methods. The system uses formant tracking and relative energy values to characterize each word in the vocabulary (the digits, 0 to 9) and also a ratio of energies in the top and bottom half of the frequency band to detect fricatives. The formants are tracked by the second derivative of a smoothed FFT (fast Fourier transform). The system was tested on a number of speakers of both sexes, with encouraging results. Conclusions are drawn about the general feasibility of a formant based approach to automatic speech recognition
