Abstract

This letter presents a method to perform the classification of speech under stress based on physical characteristics. A physical model is proposed to model airflow patterns in the physiological system in order to represent the process of speech production under psychological stress, and physical parameters characterizing airflow variations in the vocal folds, the vocal tract, and laryngeal ventricle are explored. Experimental evaluations show that the physical parameters are effective for the classification of stressed speech.
