Do vowel-contingent selective adaptation effects for place of articulation depend on vowel identity, or on the particular formant frequencies used? An experiment is reported here which tested the adaptation effects of consonants with exactly the same formant transitions before different diphthongs. In this experiment, the phonetic identity of the vowel and the formant frequencies of the consona...

While vocal tract resonances or formants are key acoustic parameters that define differences between phonemes in human speech, little is known about their function in animal communication. Here, we used playback experiments to present red deer stags with re-synthesized vocalizations in which formant frequencies were systematically altered to simulate callers of different body sizes. In response...

Perceptual and acoustic spaces obtained using MDS and PCA, respectively, for a set of Spanish vowels uttered in various fricative contexts are compared. Acoustic cues to vowel quality were studied through examination of the weights given by PCA to specific spectral regions. The acoustic space formed by the first two formant frequencies was also evaluated. The results show that MDS has serious d...

PURPOSE This study reports data on vocal fundamental frequency (fo) and the first four formant frequencies (F1, F2, F3, F4) for four vowels produced by speakers in three adult age cohorts, in a test of the null hypothesis that there are no age-related changes in these variables. Participants were 43 men and 53 women between the ages of 20 and 92 years. RESULTS The most consistent age-related ...

The present paper investigates the recoverability of detailed spectral features such as formant and burst peak frequencies of prevocalic stop consonants in noise excited channel vocoded speech for bandwidths ranging from 250-2000 Hz. It is shown that some formant frequency information is still recoverable up to 1000 Hz. This challenges the claim that listeners must necessarily rely primarily on...

PURPOSE Differences in vocal tract morphology have the potential to explain interspeaker variability in speech production. The potential acoustic impact of hard palate shape was examined in simulation, in addition to the interplay among morphology, articulation, and acoustics in real vowel production data. METHOD High-front vowel production from 5 speakers of American English was examined usi...
