Adults can learn novel phonotactic constraints from brief listening experience. We investigated the representations underlying phonotactic learning by testing generalization to syllables containing new vowels. Adults heard consonant-vowel-consonant study syllables in which particular consonants were artificially restricted to the onset or coda position (e.g., /f/ is an onset, /s/ is a coda). Su...

A visual speech training aid for persons with hearing impairments has been developed using a Windows-based multimedia computer. The training aid provides real time visual feedback as to the quality of pronunciation for 10 steady-state American English monopthong vowels (/aa/, /iy/, /uw/, /ae/, /er/, /ih/, /eh/, /ao/, /ah/, and /uh/). This training aid is thus referred to as a Vowel Articulation...

Introduction Auditory perception can be enhanced by musical training and practice. Considering the multiple brain areas involved in learning, good auditory perceptual skills contribute to phonological awareness, speech recognition presence of noise, reading, syllable recognition, other language skills. Material methods There were 30 adults between 18 27 years old who participated. They divided ...

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...

Developmental changes in the human speech production system signal age-dependent variability in the speech signal properties. In this paper, an informationtheoretic analysis of developmental changes in the speech signal is presented. The effects of age and signal bandwidth on speech signal features are analyzed especially motivated by implications to automatic recognition of children's speech. ...

Whilst studies on emotion recognition show that genderdependent analysis can improve emotion classification performance, the potential differences in the manifestation of depression between male and female speech have yet to be fully explored. This paper presents a qualitative analysis of phonetically aligned acoustic features to highlight differences in the manifestation of depression. Gender-...

The purpose of this study was to evaluate the efficiency of three acoustic modifications derived from clear speech for improving consonant recognition by young and elderly normal-hearing subjects. Percent-correct nonsense syllable recognition was measured for four stimulus sets: unmodified stimuli; stimuli with consonant duration increased by 100%; stimuli with consonant-vowel ratio increased b...

This paper examines how the strategies for L2 production utilized by foreign language learners affect the performance of non-native speech recognition. Producing English consonant clusters are the most problematic for Korean learners of English because of difference between Korean and English phonotactics. The strategies of Korean learners in producing English consonant clusters entail a large ...

The relationship of speech recognition to hearing threshold levels and to aided speech-peak sensation levels was examined in a group of severely and profoundly hearing-impaired adults. Closed-set vowel and consonant recognition tests were administered at the subjects' most comfortable levels. Both vowel and consonant recognition scores were relatively predictable from hearing threshold level at...
