Speech perception depends on the auditory system's ability to extract relevant acoustic features from competing background noise. Despite widespread acknowledgement that noise exacerbates this process, little is known about the neurophysiologic mechanisms underlying the encoding of speech in noise. Moreover, the relative contribution of different brain nuclei to these processes has not been ful...

PURPOSE To verify the effect of two approaches of vocal training in Speech Language Pathology and Audiology students, a direct and an indirect approach. METHODS Participants were 25 female Speech Language Pathology and Audiology students divided into two groups: direct training with vocal exercises, DTG (n=13); and indirect training with vocal orientations, ITG (n=12). The training sessions w...

Long-latency auditory-evoked magnetic field and potential show strong attenuation of N1m/N1 responses when an identical stimulus is presented repeatedly due to adaptation of auditory cortical neurons. This adaptation is weak in subsequently occurring P2m/P2 responses, being weaker for piano chords than single piano notes. The adaptation of P2m is more suppressed in musicians having long-term mu...

Auditory training programs are currently being explored as a method of improving hearing impaired (HI) speech perception; precise knowledge of a patient’s individual differences in speech perception allows one to more accurately diagnose how a training program should be implemented. Remapping or variations in the weighting of acoustic cues, due to auditory plasticity, can be examined with the d...

The purpose of this study was to determine the effect of augmentative visual feedback training on auditory-motor performance. Thirty-two healthy young participants used facial surface electromyography (sEMG) to control a human-machine interface (HMI) for which the output was vowel synthesis. An auditory-only (AO) group (n=16) trained with auditory feedback alone and an auditory-visual (AV) grou...

PURPOSE Research has shown that hand gestures affect comprehension and production of speech at semantic, syntactic, and pragmatic levels for both native language and second language (L2). This study investigated a relatively less explored question: Do hand gestures influence auditory learning of an L2 at the segmental phonology level? METHOD To examine auditory learning of phonemic vowel leng...

Aging disrupts neural timing, reducing the nervous system's ability to precisely encode sound. Given that the neural representation of temporal features is strengthened with musical training in young adults, can musical training offset the negative impact of aging on neural processing? By comparing auditory brainstem timing in younger and older musicians and nonmusicians to a consonant-vowel sp...

this study was an attempt to investigate the effect of vowel-recognition training on beginner and advanced iranian esl learners. a total of 36 adult iranian esl learners (18 advanced and 18 beginners) who were students of various majors at memorial university (mun) were recruited for the study. advanced participants had the experience of living in canada for at least three years while beginners...
