Abstract(in English) To discuss the relationship between perceptual diagnosis of lateral misarticulation (LM) by sophisticated listeners and its physical orrelates, two experiments using continuous speech /∫/ were performed. Experiment 1 was a comparison of the spectral envelopes of normal speech /∫/ with those of LM. Experiment 2 was detection of similarities based on auditory impressions of sophisticated listeners between LM and normal speech /∫/ with specific spectral envelope bands replaced. These experiments showed that: (1) the spectral envelopes of the LM are flat in the frequency band above approximately 4 kHz. Moreover, there is a substantial peak around 3.2kHz in the LM, which varies with time almost periodically; and (2) the replacement of the spectral envelope between 2.5 and 4.5kHz of normal continuous speech with that of LM resulted in a remarkable increase in similarity to LM based on auditory impressions. These facts suggest that the spectral envelope characteristic of the LM is nearperiodical variation around 3.2kHz.
