• Acoustic Analysis of Interdental Articulations.

抄録

The purpose of this study was to clarify the acoustical differences between normal articulation sounds [s] and Interdental articulation sounds [θ] .<BR>Power spectrograph analysis was performed to test the sounds“asa”in 16 normal articulation speakers and 16 Interdental articulation speakers. Using the Fast Fourier Transform (FFT) for the consonant [s], the ratio of energy in the high frequency area (4kHz-8kHz) to that in the low frequency area (0 kHz-4 kHz) was calculated.<BR>The results were as follows.<BR>1. Evaluation of consonant [s] sounds by the ratio of the high frequency area to the low frequency area showed Interdental articulation sounds [θ] clearly distinguished from normal articulation sounds [s] .<BR>2. In normal articulation speakers, the ratio of the high frequency area to the low frequency area was over 1.35.<BR>3. In Interdental articulation speakers, the ratio of the high frequency area to the low frequency area was below 1.30.
