A Study on Subjective Aerodynamic Measurement among the Gujarati-speaking Healthy Adults in West Cost India

Abstract

Abstract Introduction: The adequate respiratory functions are important for lifesaving like breathing, and communications such as vocalization in speech productions, and additionally, it supports for airway protective mechanisms by strengthening the protective cough. The maximum phonation duration (MPD) and maximum utterance of /s/, /Z/ and its ratio are the important aerodynamic parameters that indicate the respiratory functions and its impact on breathing, vocalization as well as protective mechanism. Aim: The aim of this study was to review and contrast the results of subjective aerodynamic assessments of maximum phonation time/duration and S/Z ratio in seconds among Gujarati-speaking healthy adult populations. Objective: The current study attempted to construct the normalization of MPD and S/Z Ratio for both males and females. Results: Mean MPD for males was greater than females, whereas s/z ratio for males and females was around 0.97 s. Conclusion: By developing normative statistics among Gujarati-speaking adult populations for both genders, it will be possible to utilize them as a reference for clinical diagnosis and for an intervention program for people with respiratory issues and other voice diseases.
