Auditory evoked potentials measured from the guinea pig temporal lobe surface reflect acoustic elements of synthesized speech syllables. Eliciting stimuli included a four formant anchor stimulus /ba/, with a 40-ms formant transition duration. The other stimuli differed from /ba/ along simple acoustic dimensions. The /pa/ stimuli differed on a VOT continuum; /da/ stimuli had a higher frequency F...

Speaking rate in general, and vowel duration more specifically, is thought to affect the dynamic structure of vowel formant tracks. To test this, a single, professional speaker read a long text at two different speaking rates, fast and normal. The present project investigated the extent to which the first and second formant tracks of eight Dutch vowels varied under the two different speaking ra...

Auditory feedback during speech production is known to play a role in speech sound acquisition and is also important for the maintenance of accurate articulation. In two studies the first formant (F1) of monosyllabic consonant-vowel-consonant words (CVCs) was shifted electronically and fed back to the participant very quickly so that participants perceived the modified speech as their own produ...

This paper presents a mathematical model of formant transitions in CV syllables of the form f(t) = fv + [(fc fv) + ct / τ] exp (-t / τ) where f(t) = frequency at time t fv = frequency of vowel target fc = frequency of formant onset c = the amount of perturbation from an exponential decay, such that the initial slope is zero for c = fc fv. τ = a time constant. This model is based on the exponent...

Comodulation of masker components can have opposite effects on detection performance: In a simple tone-innoise task, by adding comodulated masker components outside of the critical band, the performance of tone detection is improved. This effect has been termed Comodulation Masking Release (CMR, [2]). Otherwise, if comodulated flanking bands are presented in a modulation detection task, the per...
