Acoustic Analysis of Voice in Khatibs

Ms. Aswathy K P, MASLP and Dr. Rohila Shetty, Ph.D.

Abstract

Khatib is a professional voice user who is at risk of developing voice problems. Like teachers, Islamic religious officials appear to be at a high risk of acquiring voice disorders. It is critical to increase awareness of the prevalence of voice problems because there is a dearth of research on the incidence of voice abnormalities among Islamic religious authorities. The study was to analysis the acoustic characteristics among male Khatibs. It was carried out among 22 male khatibs in which 11 of them had experience of less than 20 years and 11 of them with experience of more than 20 years. The recording was carried out using PRAAT software and the analysis was done on features including fundamental frequency, jitter, shimmer and HNR. The statistical analyses for the obtained recordings were carried out using ANOVA and t test. The result shows slight variation in fundamental frequency, jitter and shimmer when analyzed between the Khatibs with more than 20 years of experience, and also with less than 20 years of experience. All acoustic parameters did not show any differences whereas on the basis of years of experience, differences were observed in the parameters like fundamental frequency, jitter and HNR. When comparing the acoustic characteristic of khatibs with other professionals, it was found that all these professionals including teachers, singers and even khatibs face problems in vocal variation showing changes in voice characteristics and less vocal strain was observed even though there is more use of voice. Therefore, it’s important for all these professionals to be aware of the vocal hygiene tips that help in the voice variation and to accelerate these tips as a management once they are in their working age.

Introduction

Voice is a crucial element of speech which is characteristically a human trait. It is an effective communication tool that not only delivers messages but also provides context (Colton & Casper, 1996). When a person speaks or sing, many muscles, including those in the mouth and throat are active. Similar to other muscles in the body, speech-supporting muscles can become tense, damaged and prone to wear and tear. Furthermore, using the incorrect strategy could give you hoarseness. A professional voice user is an individual who uses his/her voice for livelihood. Overuse, abuse or the misuse of voice are features of functional vocal disorders. The cause could be physiological changes brought by environmental exposure (allergies), hormonal changes, or other systemic illnesses that affects the voice, such as acid reflex disease (GERD), acute infectious laryngitis and benign vocal fold masses.
