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 Arabic-speaking 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.
