简要总结
Prosody is the melody and rhythm of speech, it is used to refer to the supra segmental aspects of speech including pitch, loudness and duration. Variations in these features achieve different prosodic functions and are perceived by the listener as meaningful changes. The role of prosody in language acquisition and effective communication is documented in research. Nevertheless, prosodic intervention in children with hearing impairment received less attention compared to other speech and language areas.
The aim of this study is to adapt the "prosody treatment program", an evidence based rehabilitation program, and to detect the efficacy of its activities in improving the prosodic skills of Egyptian hearing impaired children.
The "prosody treatment program" is an evidence-based practice targeting receptive and expressive prosodic skills in addition to speech production, intelligibility, pragmatics and phonology. The program is applied using a systematic approach of providing cues following the principles adapted from dynamic temporal and tactile cueing (DTTC) for speech motor learning to help accelerate the child's learning of the prosodic skills targeted in this program. The program was translated to Arabic and adapted to be suitable for the Egyptian children.
详细描述
Prosody has an important role in several areas of communicative functions including : grammatical, pragmatic, affective and/or indexical functions. Prosodic abnormalities extend across a wide range of communication disorders. Intact functioning auditory system has a fundamental role in language acquisition and development. Children receive the speech of others as a source of linguistic input which is considered their target and they gradually modify their productions using their own auditory feedback to reach the target utterance.
Hearing impairment early in life deprives the child of the source of their linguistic input affecting various aspects of speech and language development. Speech production of the hearing impaired is characterized by various segmental and suprasegmental errors.
Case studies show that interventions targeting prosody can modify prosody in young children with speech and language impairments. Multiple problems of prosody , language, speech and voice are found in individuals with prosodic impairments ,therefore it is challenging to develop treatment protocols addressing prosody .There are only few published interventions targeting prosody .
Due to lack of well structured comprehensive Arabic programs targeting prosody , this work was dedicated towards adaptation of "prosody treatment program" a remediation program targeting receptive and expressive prosodic skills and its application on hearing impaired children .The proposed program targets two levels: preschool and school aged children.
The aim of this work was to adapt the "prosody treatment program" program and apply its activities in cases of hearing impairment to detect its efficacy in improvement of prosodic skills in Egyptian hearing impaired children fitted with hearing aids or cochlear implant devices.
