Frequency and duration discrimination of short first-formant speechlike transitions.
Frequency and duration discrimination thresholds of short rising and falling one-formant speechlike transitions without a steady state were determined by means of same/different paired comparison tasks in two experiments. When frequency extent is varied (experiment 1), just noticeable differences decrease with increasing transition duration. Expressed in Hz, thresholds are, on average, 70, 63, ...
متن کاملHuman frequency-following responses: representation of second formant transitions in normal-hearing and hearing-impaired listeners.
Auditory nerve single-unit studies have demonstrated that phase-locking plays an important role in the neural encoding of the spectrum of speech-like sounds. Recently, it has been reported that the phase-locked activity underlying the scalp-recorded human frequency-following response (FFR) also encodes the first two formants of several steady-state vowels and the time-variant frequency presente...
متن کاملThresholds for second formant transitions in front vowels.
Formant dynamics in vowel nuclei contribute to vowel classification in English. This study examined listeners' ability to discriminate dynamic second formant transitions in synthetic high front vowels. Acoustic measurements were made from the nuclei (steady state and 20% and 80% of vowel duration) for the vowels /i, I, e, epsilon, ae/ spoken by a female in /bVd/ context. Three synthesis paramet...
متن کاملDifference limen for formant frequency discrimination at high fundamental frequencies
In previous studies of formant frequency discrimination, variation in the stimuli has mainly concerned the formant frequencies while other factors which may affect formant frequency discrimination have largely been ignored. In most studies, fundamental frequencies typical of adult male speakers have been used. In the study presented here, formant frequency discrimination as a function of fundam...
متن کاملPredictions of formant-frequency discrimination in noise based on model auditory-nerve responses.
To better understand how the auditory system extracts speech signals in the presence of noise, discrimination thresholds for the second formant frequency were predicted with simulations of auditory-nerve responses. These predictions employed either average-rate information or combined rate and timing information, and either populations of model fibers tuned across a wide range of frequencies or...
