A software speech recognition system using a phonetic approach.Everson, L Robert H. January 1985 (has links)
Computer speech recognition techniques were investigated. This investigation included a study of the hearing and speech process. An
algorithm was developed that used nine features to identify the phonemes in speech signals. Two of these features, the total energy and the number of zero crossings in a specific section of the speech signal, were obtained
directly from the digitized speech signal. The other features, frequency energy bands and formant frequencies, were measured from a spectral analysis of the signal. A Hewlett Packard mini-computer was used for the development of the necessary software in FORTRAN. For the testing of the algorithm ten words, "zero" through to "nine" were used. / Thesis (M.Sc.)-University of Natal, 1985.

A comparative study of various speech recognition techniques.Pitchers, Richard Charles. January 1990 (has links)
Speech recognition systems fall into four categories,
depending on whether they are speaker-dependent or
independent of speaker population and on whether they are
capable of recognizing continuous speech or only isolated
words.
A study was made of most methods used in speech recognition
to date. Four speech recognition techniques for
speaker-dependent isolated word applications were then
implemented in software on an IBM PC with a minimum of
interfacing hardware. These techniques made use of short-time
energy and zero-crossing rates, autocorrelation
coefficients, linear predictor coefficients and cepstral
coefficients. A comparison of their relative performances
was made using four test vocabularies that were 10, 30,
60 and 120 words in size. These consisted of 10 digits,
30 and 60 computer terms and lastly 120 airline reservation
terms.
The performance of any speech recognition system is
affected by a number of parameters. The effects of frame
length, pre-emphasis, window functions, dynamic time
warping and the filter order were also studied experimentally. / Thesis (M.Sc.-Electronic Engineering)-University of Natal, 1990.
