Certain of the complex spectral effects of vowel nasalization bear a resemblance to the effects of modifying the tongue or jaw position with which the vowel is produced. Perceptual evidence suggests that listener misperceptions of nasal vowel height arise as a result of this resemblance. Whereas previous studies examined isolated nasal vowels, this research focused on the role of phonetic conte...

This study examined the effect of interruption parameters (e.g., interruption rate, on-duration and proportion), linguistic factors, and other general factors, on the recognition of interrupted consonant-vowel-consonant (CVC) words in quiet. Sixty-two young adults with normal-hearing were randomly assigned to one of three test groups, "male65," "female65" and "male85," that differed in talker (...

Vowel identification in noise using consonant-vowel-consonant (CVC) logatomes was used to investigate a possible interplay of speech information from different frequency regions. It was hypothesized that the periodicity conveyed by the temporal envelope of a high frequency stimulus can enhance the use of the information carried by auditory channels in the low-frequency region that share the sam...

in this paper, the validity of the key prediction of adaptive dispersion theory was tested. according to this prediction, vowels of a given language are organized in such a way that they are sufficiently distinct on the perceptual level. it implies that more crowded inventories, which also have wider f1 dimension, occupy greater vowel spaces than inventories with fewer vowels.  to investigate t...

introduction: on the importance of the formant frequency, it is enough to say that the first three formants of a vowel and their internal relationships are the major components in detection of vowel type by listener. moreover, the quality of a vowel depends on its factorial frequencies. the main application of measuring factorial frequency is for description of vowel errors because recognizing ...

The dynamic specification account of vowel recognition suggests that formant movement between vowel targets and consonant margins is used by listeners to recognize vowels. This study tested that account by measuring contributions to vowel recognition of dynamic (i.e., time-varying) spectral structure and coarticulatory effects on stationary structure. Adults and children (four- and seven-year-o...

English monolinguals and native Spanish speakers of English used a 9-point scale to rate syllable-initial stops for goodness as realizations of the English /p/ category. Voice onset time (VOT) was varied in a set of short-duration ('fast-rate') consonant-vowel (CV) stimuli, and in a set of longer-duration ('slow-rate') CV stimuli. The VOT values ranged from values typical for English /b/ to val...

The mismatch negativity (MMN) was recorded from 10 young adults with normal hearing using naturally produced speech contrasts. Consonant-place and vowel-height contrasts were examined in consonant-vowel (CV) syllables by pairing either the consonant /t/ or /p/ with the vowel /I/ or /E/. Vowel-height was also examined as a pseudovowel; one cycle of the vowel segment of a CV was extracted and rep...
