Two Multivariate Statistical Computer Programs and Their Application to the Vowel Recognition Problem
Peter D. Welch, Richard S. Wimpress · The Journal of the Acoustical Society of America · 1961
This paper describes two IBM 704 EDPM programs which were written to aid in the development of mechanical speech recognition devices. Both are based upon multivariate statistical techniques. It further describes the application of the two programs to the problem of vowel recognition using fundamental frequency and formant information.
