Description
An isolated word recognition system for the words zer o
through nine has been implemented using an IBM Personal
Computer AT with a Data Translation DT2821 12-bit data
acquisition card . The software has been written f o r the
80286 based machine in assembly and compiled basic. Since
this research was aimed at defining techniques that could
work for speech recognition, real time recognition was not
a goal.
Three techniques were tested for speech recognition.
The first method tried to match entire words, using the
fast Fourier transform, the fast Walsh transform, the
average magnitude function, and the zero crossing rate.
The second method used the short-time fast Fourier
transform to recognize the phonemes, then the words. The
third method used a digital filter generated from I in ear
predictive coding coefficients and the zero crossing rate
to recognize the phonemes and words. A recognition rate of
98 percent was achieved for a single user for the words
zero through nine.
