One can discriminate exactly whether the speaker speaks spontaneously or reads something. It is supposed that the rhythm informs these speech modalities. In this study it would be defined that the rhythm consists of the sound group and the pause. And this hypothesis was estimated by the comparison between the physical discrimination and the auditory discrimination of these modalities by the rhythm. By considering these relations it is expected to discribe one of the auditory or the acoustical abilities. Procedures Physical analysis: Four monologues in two speech modalities were obtained from each of 14 sample subjects. In the one modality, the instructions were to tell stories of two cartoons according to the presented sets of pictures. In the other, the same subject was asked to read two stories attached to the same cartoons at his own speed. All speakers were Japanese undergraduates, and were free of speech disorders or hearing disosders. The tape-recorded speech samples were analyzed through the process of an original electric-transmitter and the "Lectiphory 8s" into the sound-silence patterns on the recording sheets. The sampling rate of duration was 0.3sec. each. And thus Markovian process and measurement of rhythm were predicted. Then, with this physically defined rhythm speech modalities were discriminated objectively. Relations between speech-reading discrimination and perception of rhythms: Five materials were sampled according to measurement of rhythms. Nine subjects were instructed to hear, and judge the speech modalities and the rhythms by the method of paired comparison. Results 1. The results of the tests about frequency distribution showed that the duration time of vocalization in readings was longer than that of speeches, and they also showed that the duration of pause in speech was longer than that of reading. 2. The models of rhythms matched two speech states. And the models of rhythms (Y) were predicted by 55 out of 56 speeches and readings as the function of the Markovian processes and uncertainty. 3. The perception of the rhythm was matched with the rhythm physically measured. 4. The differences between the speech modalities were perceived identically by men. Conclusion Thus the sound group and pause can be supposed to measure one of the auditory or the acoustical abilities.
