Inter-Channel Parameters for the Diagnosis of the Laryngeal Functions

Abstract

Speech, airflow and electroglottogram are widely used for the diagnosis of the laryngeal function. But, in most cases these signals were analyzed separately and only combined subjectively by the reviewers. By simultaneous measurements and integration of these signals objectively, we can derive new diagnostic information quantitatively. Here, we propose a new inter-channel parameter CDR (Closure Delay Ratio) that is estimated from three-channel signals measured simultaneously; speech, EGG and airflow. This new parameter CDR makes the classification of patients with larynx diseases from normal subjects more confident.
