Effects of signal level and spectral contrast on vowel formant discrimination for normal-hearing and hearing-impaired listeners.
PURPOSE The aim of this study was to determine whether increasing the overall speech level or the individual spectral contrasts of vowel sounds can improve vowel formant discrimination for listeners both with and without normal hearing. METHOD Thresholds of vowel formant discrimination were examined for the F2 frequencies of 3 American English vowels for listeners with and without normal hear...
متن کاملFactors affecting vowel formant discrimination by hearing-impaired listeners.
The goal of this study was to measure the ability of adult hearing-impaired listeners to discriminate formant frequency for vowels in isolation, syllables, and sentences. Vowel formant discrimination for F1 and F2 for the vowels /I epsilon ae / was measured. Four experimental factors were manipulated including linguistic context (isolated vowels, syllables, and sentences), signal level (70 and ...

Raised and lowered larynx positions have been studied on two subjects and in a model experiment. Good qualitative agreement was found and i t was concluded that the main effect s tems f rom the shortening o r lengthening of the pharyngeal cavity.
متن کاملAn effect of formant amplitude in vowel perception
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 amp...
متن کاملEffect of vowel on pitch discrimination of CV in Japanese
The pitch dynamics seem to be based on the pitch thresholds (DLs) between the Vowels, V and CV, and also CV and CV. In this study, the DLs were measured for discrimination of pitch (fundamental frequency) of complex tone, Japanese Vowel (V) and Consonance-Vowel (CV) speech. A nominal F0 of complex tone was 170 Hz and the pitch of V and CV speech were resynthesized same as 170Hz. Tone was band-p...
