Background: For unilateral cochlear implant (CI) candidates, benefit can be enriched by adding a hearing aid to the opposite ear, termed bimodal hearing. The best results are obtained when their hearing, speech, and language abilities are properly verified. The Arabic version of auditory perception of alphabet letters (APAL) is a reliable test of speech perception appropriate for use with kids who speak Arabic but have hearing impairment and a limited vocabulary. Aim: Children who use linked hearing aids and cochlear implants were evaluated to test the correlation between the (APAL) test and auditory abilities, language acquirement and speech parameters. Design: Eleven children were studied twice first 3 months after unilateral CI turn on and second 3 months after fitting linked hearing aid (HA) in non-implanted ear (6 months after CI turn on). Assessment of APAL test was performed in the audiovestibular medicine department and the evaluation of speech characteristics, language, and auditory skills in the ENT department's Phoniatric Unit. Zagazig University. The findings were compiled and statistically evaluated. Results: A statistically significant increase in correct scores of APAL test as well as language and auditory assessment after bimodal stimulation. There was a statistically significant +ve correlation (r=0.70 & p=0.02) between APAL and CAP among the studied cases. Conclusion: APAL can be regarded as a reliable speech discrimination test that predicts the progress of a number of prelingual bimodal children's skills.
Background:The purpose of this study was to develop and verify the test materials for a speech perception testing for adults in Libya. Such materials are useful for administering speech evaluations to native Arab adults who speak with a Libyan accent. Objective: This study is a component of a larger initiative to prepare and validate the speech materials for the Arabicspeaking community in Libya. Methods: In this cross-sectional study, two lists of bisyllabic (spondees) words and monosyllabic phonetically balanced words were constructed . The two selected 100-bisyllabic and monosyllabic word lists were presented to 120 normal hearing participants with the age range of 18 to 50 years. Tests of validity and reliability were conducted to assure the suitability of this material for the speech regocnition test and speech discrimination score (SRT and SDS). Results: The two developed Libyan word lists (SRT and SDS) showed high face and content validity, kappa P-value was <0.001 with high signifiicant, Cronbach`s alpha coefficient was 0.82, 0.71 for the (SRT and SDS) respectively, and intra-class correlation coefficients reliability (p<0.001) were also statstically significant.
Conclusion:The data analysis shows that the SRT of both Libyan and Egyptian lists have high degree of validity and reliability. Meanwhile, SDS of Libyan accent list is of higher statistical significance than Egyptian list. As a result, the scale's development of the Libyan accent has strong psychometric characteristics, making it suitable for usage in the Libian region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
