The discrimination of vowel duration by infants.
Three groups of nine 5-11-month-old infants provided evidence of discrimination of speechlike stimuli differing only in vowel duration. Ease of discrimination was directly related to the magnitude of the ratio of the longer to shorter vowel. Group one infants discriminated three vowel duration contrasts (with ratios of 0.33, 0.67, and 1.0) embedded in a synthetic [mad] syllable; group two discr...
متن کاملDuration and F0 as perceptual cues to Japanese vowel quantity
Vowel duration and local fundamental frequency changes are investigated as acoustical cues to vowel quantity identification by Japanese listeners. To examine the role of these factors, a perception experiment was carried out. The results indicate that, even though vowel duration serves as a dominant perceptual cue, when vowel quantity cannot be adequately cued by vowel duration alone, the F0 in...
متن کاملA, v, and AV discrimination of vowel duration
Discrimination of vowel duration was explored with regard to JNDs, error bias, and effects of modality and consonant context. 90 normal-hearing participants discriminated either auditorily, visually, or audiovisually between pairs of stimuli differing with regard to duration of the vowel /a/. Duration differences varied in 24 steps: 12 with the first token longer and 12 with the second token lo...
متن کاملEffect of Duration, Intensity, and F0 Alternations on Rhythmic Grouping
Stress patterns in language play a large role in how we perceive speech. Stress is assigned on the basis of duration, intensity, and F0. This study investigated the role that duration, intensity, and F0 play in rhythmic grouping. Subjects were presented with sequences of alternating squarewave segments that were varied on one of the aforementioned dimensions. They were asked to indicate whether...
متن کاملInfluences of vowel duration on speaker-size estimation and discrimination
Several experimental studies have shown that the human auditory system has a mechanism for extracting speaker-size information, using sufficiently long sounds. This paper investigated influence of vowel duration on the processing for size extraction using short vowels. In a size estimation experiment, listeners subjectively estimated the size (height) of the speaker for isolated vowels. The res...
