What is the purpose of the electronic transducer in voice assessment?

The purpose of the electronic transducer in voice assessment is to measure chest wall displacement. This function is essential in voice assessments because it helps in understanding the respiratory mechanics that contribute to voice production. The chest wall's movement during breathing reflects the dynamics of the respiratory system and how it supports vocalization. Monitoring this displacement can provide valuable insights into a person's respiratory capacity, coordination, and stability, all of which are critical for effective voice production.

In contrast, while filming vocal fold movement, detecting airflow rates, or visualizing articulators are important aspects of voice assessment, these tasks are typically accomplished using different tools and methods, such as endoscopes for visualizing vocal folds or specialized devices for measuring airflow. Hence, the specific role of the electronic transducer centers on quantifying the movements of the chest wall, which are integral to both breathing and voice.
