An automatic speech recognition system based on the reference set of a single speaker can be extended for use by several speakers by applying appropriate preprocessing transformations. These transformations adapt the incoming patterns of a new speaker to the patterns of the reference set. Under the present restriction to vowel spectra adaptation methods by spectral amplitude weighting and by spectral shifting are investigated. By a special method it was enabled to adapt test spectra class specifically.
