An effect of formant amplitude in vowel perception
نویسندگان
چکیده
A psycho-acoustical experiment was conducted using synthetic vowel-like stimuli to examine effect of formant amplitude in vowel perception. Nine combinations of formant frequencies were examined. For each combination, relative amplitude of the third to the second formants was modified in seven degrees. In eight of the nine combinations, perceived vowels were changed according to the formant amplitude although every formant frequency kept constant. Furthermore, this amplitude effect was observed even when frequency separation of the neighboring formants was greater than 3.5 Bark. The result suggested that formant amplitude is effective cue for vowel perception as well as formant frequency.

The role of formant amplitude in the perception of /i/ and /u/.
Although recent evidence reconfirmed the importance of spectral peak frequencies in vowel identification [Kiefte and Kluender (2005). J. Acoust. Soc. Am. 117, 1395-1404], the role of formant amplitude in perception remains somewhat controversial. Although several studies have demonstrated a relationship between vowel perception and formant amplitude, this effect may be a result of basic auditor...
متن کاملRelative importance of formant and whole-spectral cues for vowel perception
Three psycho-acoustical experiments were carried out to investigate relative importance of formant frequency and whole spectral shape as cues for vowel perception. Four types of vowel-like signals were presented to eight listeners. The mean responses for stimuli including both formant and amplitude-ratio feature were quite similar to those for the stimuli including only formant peak feature. No...
متن کاملHigher formant normalization results from auditory integration of F2 and F3.
Two experiments were conducted to test the hypothesis that higher formant normalization results from the auditory integration of F2 and F3 when they are within 3 Bark of each other. In the first experiment, Formants 3-5 were manipulated in both a "hid"-"head" continuum (in which F2 and F3 are within 3 Bark of each other) and a "hood"-"HUD" continuum (in which F2 and F3 are not within 3 Bark of ...
متن کاملINFLUENCE OF VOCALIC CONTEXT ON PERCEPTION OF THE [ J [ s ] DISTINCTION : II . SPECTRAL FACTORS
The posi tion of the category boundary along a synthetic [J J-[ sJ noise continuum depends on the following vocalic segment: When the vowel is [u], more "s" responses are given than when the vowel is [aJ. In Experiment I, we showed that this context effect disappears when the vocal ic portion is synthesized so as to contain no formant transitions. To dissociate the contribution of formant trans...
متن کاملEffects of duration and formant movement on vowel perception
Acoustical analysis of speech and perceptual studies indicate that the dominant acoustic correlates of vowel perception are the frequencies of the first three formants. However, most vowels are not completely steady-state (even in isolation) and formant frequencies change with variation in the surrounding consonantal context, prosodic influences, speaking rate, and vocal tract length of the tal...
