Acoustic and Prosodic Features in Quran Recitation with a Focus on the Recitation by Master Abdulbasit

Objective: The Scientific Society of Speech Therapy considers professional voice users within the specialized field of speech therapy. This field has various branches, including the recitation of the Holy Quran. Thus, we embarked on researching the domain of distinguished and legendary Quran reciters such as Master Abdulbasit to obtain quantitative evidence of their capabilities for use in the training of aspirants. The purpose of this study is to quantitatively describe the acoustic and prosodic features of the late Abdulbasit during his Quranic recitation.

Methods/Design: This was a cross-sectional study that focused on 10 Surahs (sections) of the Quran recited by the late Abdulbasit. Voice samples were analyzed using the Praat software. Acoustic features such as frequency, intensity, and voiced sounds were measured. Features like Tahrir (professional articulation), target vowels in Tahrir, types of Tahrirs, changes in intensity and note during recitation, as well as the pitch contour were also examined.

Results: For example, findings from the recitation of Surah “Nasr” are highlighted. The results showed an average frequency of 225 Hz, a frequency range change of about 110 Hz, which is less than one octave. The sound height increases in open vowels. Open vowels are produced louder than closed vowels. Producing a vowel with a constant note happens in specific places. The pitch contour aligns with the content of the verse.

Conclusion: The recitation of this Qari (reciter) is based on the fundamental principles of phonetics, acoustics, and prosodic. These patterns can be used in the scientific teaching of Quran recitation.
