title: Fundamental frequency, intensity, and vowel duration characteristics related to perception of Cantonese alaryngeal speech.
abstract: Fundamental frequency (F(0)), F(0) contours, vowel duration, and intensity associated with Cantonese alaryngeal speech, and their relation to the perception of meaning were studied. Thirty adult male native Cantonese speakers participated in the study: 10 esophageal, 10 electrolaryngeal, and 10 laryngeal speakers. Results indicated that perceptually, listeners were able to identify what the Cantonese esophageal speakers were saying, particularly for words associated with high-level, low-falling and high-rising tonal contours. Acoustic analysis of the speech signals of the esophageal speakers indicated that intensity and durational data did not contribute to the perception of meaning. The F(0) contours appeared to be the acoustic cues associated with the signal that contributed most to the perception of meaning.
