Background And Objective: According to Klassen et al. (2012), the overall quality of life of CL/P children is most affected by appearance and quality of speech, as these differences are most noticeable to others. To what extent changes in craniofacial growth have an impact on speech quality has yet to be clarified.

Most children born with cleft palate (CP) or cleft lip and palate (CL/P) have velopharyngeal insufficiency (VPI), some degree of hypernasal resonance, articulation disorders and laryngeal dysphonia. Combination of different CL/P specific problems may mask laryngeal dysphonia and therefore, it may remain undiagnosed and untreated by clinicians. The research aimed to study the effect of VPI on voice quality in Estonian CL/P children.

Normative nasalance scores are essential for the treatment and assessment purposes for clinicians. Till date, no studies have been done on nasalance in Estonia. This research was conducted to develop Estonia-specific optimized speech stimuli for Nasometer II and establish the normative nasalance scores.

Objective: The Nasometer is increasingly being used to complement auditory perceptual assessment of nasality. Nasalance scores which are obtained from the Nasometer vary across languages. Normative nasalance scores have been established for many languages but not for the Vietnamese language.
