Standardization of nasalance scores in normal Saudi speakers

Abstract

Objective. The aims of this study were to obtain normative nasalance scores for a normal Saudi population with different ages and genders, to develop nasometric Arabic speech materials, and to make cross-linguistic comparison.

Subjects. Participants included 219 normal Saudi native monolingual Arabic speakers of different ages. Subjects were classified into four groups according to age and gender. Subjects did not have any history of oral, nasal, or velopharyngeal abnormality.

Methods. Arabic speech samples were developed to evaluate nasalance scores, which included syllables repetition, three oral sentences, three oro-nasal sentences, and three nasal sentences. Nasalance data were obtained using Nasometer II–6400.

Results. Normative nasalance values were determined. Significant differences between the male and female children groups were noticed in many parameters. Nasalance scores were higher in adults, with significant differences between all groups.

Conclusion. Normative nasalance scores for Saudi Arabic speakers have been developed for both adults and children. The Arabic speech materials developed in this study appear to be easy to use and applicable for different age groups.
