Cross-Cultural Adaptation and Validation of the Voice Handicap Index Into Estonian.

Objectives: This study aimed to validate the Voice Handicap Index (VHI-30) for the Estonian language and determine its psychometric properties.

Study Design: Cross-sectional and comparative study, combining subjective and objective methods.

Methods: The objective data included voice recordings analyzed using the PRAAT software, which calculates the Acoustic Voice Quality Index (AVQI) to assess voice quality.

Pilot study: Correlation between nasalance scores and cephalometric parameters in Estonian cleft palate children.

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.

The effect of velopharyngeal insufficiency on voice quality in Estonian Children with Cleft Palate.

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.

Nasalance scores for Vietnamese-speaking children with oral clefts.

Objective: The study aimed to obtain nasalance scores for Vietnamese-speaking patients with repaired cleft palate with or without cleft lip.

Methods: A total of 29 children with cleft palate with or without cleft lip (4-18 years old, mean age 7.9±3.

Normative nasalance scores for Estonian 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.

Normative nasalance scores for Vietnamese-speaking children.

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.
