Abstract | Purpose: This investigation compared high-cost and low-cost options for obtaining acoustic and aerodynamic voice measures and evaluated differences between males and females for each of the dependent variables. Methodology: Forty healthy participants were recorded performing various acoustic (vowel, speech) and aerodynamic (vital capacity, airflow) tasks with both high and low-cost equipment. Recorded voices were analyzed with PRAAT and CSL and aerodynamic measures were obtained with PAS and a hand-held spirometer. Results: Strong, statistically significant relationships were found between high and low-cost equipment for measures of vital capacity, cppV, and cppS, and a moderate-to-strong relationship was found for airflow measures (EMFR/TarAirflow). Significant differences between males and females were found for measures of vital capacity, cppV, and cppS. Conclusions: Because of the strong reliability found between equipment types, we concluded that either high or low-cost equipment is a valid option to conduct laryngeal function studies. The significant effects of sex found in this study are supported by the existing body of literature. The results suggest that the high-cost and low-cost instrumentation used in this study are both valid options for use in clinical voice evaluations. |
