One issue in language acquisition is whether the acoustic cues used in the L1 can be used to perceive a different phonemic contrast in the L2. A previous study found that Japanese listeners can utilize their sensitivity to vowel duration in their L1 to identify the English coda voicing contrast when asked to classify each token as 'bit' or 'bid'. That is, they could use vowel duration in a way ...

OBJECTIVE This clinical trial investigated the ability of concurrent speech segregation in hearing impaired children. The auditory behavioral responses and auditory late responses (ALRs) were compared between test and control groups prior to vowel auditory training and after 3 and 6 months of vowel auditory training to find the effects of bottom-up training on concurrent speech segregation in h...

The aim of this experiment was to determine whether patients who use the Ineraid cochlear implant code formant frequency by means of the information in the time waveforms presented to the electrodes, or by the information in the distribution of energy among the electrodes. Six patients were presented three vowels for identification. The vowels were presented in two configurations. In one, the t...

The rapid momentum of the technology progress in the recent years has led to a tremendous rise in the use of biometric authentication systems. The objective of this research is to investigate the problem of identifying a speaker from its voice regardless of the content (i.e. text-independent), and to design efficient methods of combining face and voice in producing a robust authentication syste...

Difficulties with second-language vowel perception may be related to the significant challenges in using acoustic-phonetic cues. This study investigated the effects of perception training with duration-equalized vowels on native Chinese listeners' English vowel perception and their use of acoustic-phonetic cues. Seventeen native Chinese listeners were perceptually trained with duration-equalize...

Two experiments are reported that extend previous investigations of the influence of the lexicon on visual spoken word recognition. Experiment 1 investigated individual differences in segment level perception. Behavioral identification of consonants and vowels presented in either consonant-vowel or consonant-vowel-consonant nonsense syllables were collected from participant groups chosen to dif...

We investigate the perception of phonemic vowel quantity contrast and its relation to word stress and vowel quality in Slovak, and fill the gap of missing experimental perception data for this language. We observe that both prosodicallydriven undershoot of unstressed vowels and the functional load affect the perception of quantity contrast. Vowel quality plays some role in quantity identificati...

This study explores the effects of vowel duration in identifying the previous stop laryngeal contrast in Korean. The durational resolution in Korean shows a limited variation of syllable duration and a strong correlation between VOT and vowel duration [1]. The systematic variation of vowel duration due to different VOTs of prevocalic stops suggests vowel duration as a plausible perceptual cue i...
