PURPOSE To study the role of visual perception of phonemes in visual perception of sentences and words among normal-hearing individuals. METHOD Twenty-four normal-hearing adults identified consonants, words, and sentences, spoken by either a human or a synthetic talker. The synthetic talker was programmed with identical parameters within phoneme groups, hypothetically resulting in simplified ...

Learning language is one of the most complex and intriguing feats of learning that humans achieve; but how we do it remains obscured behind many layers of questions we have yet to answer. Each small advance, however, moves us one step closer to understanding this incredible process. One aspect of this problem that has been explored substantially is word learning. In principle, understanding how...

The temporal lobe in the left hemisphere has long been implicated in the perception of speech sounds. Little is known, however, regarding the specific function of different temporal regions in the analysis of the speech signal. Here we show that an area extending along the left middle and anterior superior temporal sulcus (STS) is more responsive to familiar consonant-vowel syllables during an ...

“Phonemic variability and confusability in pronunciation modeling for automatic speech recognition”

Despite the importance of phonemic awareness in beginning literacy, several studies have demonstrated that adults, including teacher trainees, have surprisingly poor phonemic skills. Three experiments investigated whether adults’ responses in phonemic awareness and spelling segmentation tasks are based on units larger than single letters and phonemes. Responses often involved large units, and t...

while parkinson's disease (pd) has traditionally been defined by motor symptoms, many researches have indicated that mild cognitive impairment is common in non-demented pd patients. the purpose of this study was to compare verbal fluency performance in non-demented parkinson's disease patients with healthy controls.in this cross-sectional study thirty non-demented parkinson's disease patients a...

BACKGROUND For word production, we may consciously pursue semantic or phonological search strategies, but it is uncertain whether we can retrieve the different aspects of lexical information independently from each other. We therefore studied the spread of semantic information into words produced under exclusively phonemic task demands. METHODS 42 subjects participated in a letter verbal flue...
