Normative Acoustic Voice Parameters in Native Arabic-Speaking Children and Adults Using Praat Software

Area of Science:

• Speech and Hearing Sciences
• Acoustic Phonetics
• Voice Disorders Research

Background:

• Normative voice data is crucial for identifying voice pathologies.
• Existing acoustic voice data often lacks representation for diverse linguistic groups.
• Praat software offers a robust platform for acoustic voice analysis.

Purpose of the Study:

• To establish normative acoustic voice parameters for native Arabic-speaking adults and children.
• To utilize Praat software for comprehensive voice data collection and analysis.
• To provide a foundational dataset for future voice disorder research in this population.

Main Methods:

• Eighty healthy adults (21-50 years) and 29 children (6-12 years) participated.
• Acoustic voice analysis was performed using Praat software.
• Key parameters measured included fundamental frequency (F0), jitter, shimmer, NHR, and CPPS for sustained vowels /a/ and /i/.

Main Results:

• Distinct normative values were established for adult males, adult females, and children.
• Significant differences in fundamental frequency, jitter, and CPPS were observed between adult genders.
• Minimal age-related variations were noted, and no significant gender differences were found in children.

Conclusions:

• This study presents the first reference data for acoustic voice parameters in native Arabic speakers.
• The established norms serve as a vital tool for the clinical assessment of voice disorders.
• The findings highlight the importance of gender-specific normative data for adult voice analysis.
