since cochlear implants can now be provided for children before the age of 1 year, the development of a family-centered habilitation program is essential for this age group. the present study was done to investigate the effectiveness of navayesh” auditory habilitation program on communication skills of cochlear implantation candidates. 32 mothers along with their 3-12 months deaf infants partic...

In the first topic, we shall discover that sound/speech perception is not as simple as bunch of dancing hair cells. Instead, pyscho-acoustical experiments have shown complex phenomena in sound perception, such as hearing thresholds, non-linear relationship between intensity and loudness, and temporal/simultaneous masking. We also briefly discuss the difficulty of speech perception research and ...

A neurocomputational model of speech production and speech perception is introduced. After training, i.e. after mimicking early phases of speech acquisition, the model is capable of producing and perceiving vowels and CV-syllables (C = voiced plosives). Different instances of the model were trained for representing different “virtual subjects” which are then used as listeners in identification ...

OBJECTIVE This study investigated factors contributing to speech perception outcomes in children with prelingual deafness after 4 to 7 yr of multichannel cochlear implant use. The analysis controlled for the effects of child, family and implant characteristics so that educational factors most conducive to maximum implant benefit could be identified. DESIGN One hundred eighty-one 8- and 9-yr-o...

This article discusses recent functional magnetic resonance imaging (fMRI) and repetitive Transcranial Magnetic Stimulation (rTMS) data that suggest a direct involvement of premotor cortical areas in speech perception. These new data map well onto psychological theories advocating an active role of motor structures in the perception of speech sounds. It is proposed that the perception of speech...

Listening to speech recruits a network of fronto-temporo-parietal cortical areas. Classical models consider anterior (motor) sites to be involved in speech production whereas posterior sites are considered to be involved in comprehension. This functional segregation is challenged by action-perception theories suggesting that brain circuits for speech articulation and speech perception are funct...

Speech perception is thought to be linked to speech motor production. This linkage is considered to mediate multimodal aspects of speech perception, such as audio-visual and audio-tactile integration. However, direct coupling between articulatory movement and auditory perception has been little studied. The present study reveals a clear dissociation between the effects of a listener's own speec...
