Abstract : This report examines the physical and perceptual identification of Czech vowels. A new complex method of speech analysis is introduced. It consists of evaluating the physical speech parameters in combination with the perceptual parameters, i.e., those obtained from the results of listening tests. The physical parameters are determined with the aid of three-dimensional spectrograms of the visible-speech type. The perceptual parameters are the results of test-listening to acoustical speech signals deformed along the time or frequency axes, i.e. by either a gating circuit or a frequency pass-filter. The way of applying the method is shown on examples and results, the values being obtained in evaluating Czech positional and stylistic vowel variants. One result of the method is the determination of the relevant vowel regions from the perceptual viewpoint.
