Abstract

Background

Chronic obstructive pulmonary disease (COPD) is a respiratory condition that can affect voice as respiration is the source for voice production. There are very few studies available on the analysis of voice in individuals with COPD (asthma, chronic bronchitis and emphysema).

Purpose of the study

The aim of this study was to analyze the acoustic and perceptual characteristics of voice in individuals with COPD.

Method

The study followed a comparative cross-sectional study design. Sixty-four participants were considered, and they were divided into two groups (group 1: individuals with COPD, n = 32; group 2: normal individuals, n = 32). Acoustic analysis was performed using CSL software. The perceptual analysis was done using CAPE-V.

Results

The results showed that there was significant difference between the two groups on acoustic measures (lower fundamental frequency, reduced frequency range, increased pitch and amplitude perturbation measures and increased noise measures), and perceptual measures (presence of increased roughness, breathiness, strain).

Conclusion

We can conclude that COPD has an impact on voice measures as assessed through acoustic and perceptual parameters. These voice deviations may be due to COPD itself or due to the effects of the medication.

Clinical implication

The findings of this study provide valuable information regarding voice problems in the individuals with COPD so that an appropriate intervention plan can be designed.
