The present study was performed to investigate and discuss the aerodynamic characteristics of whispered and normalspeech during reading paragraph tasks. 39 normal females(18-23 yrs.) read ‘Autumn’ paragraph with whispered and normalphonation. Their readings were recorded and analyzed by ‘Running Speech’ in Phonatory Aerodynamic System(PAS)instrument. As results, during whispered speech, the total duration was longer and the numbers of inspiration were morefrequently shown than normal speech. The Peak expiratory and inspiratory rate were higher in normal speech, but theexpiratory and inspiratory volume were higher in whispered speech. By correlation analysis, both whispered and normalspeech showed significantly high correlation between total duration and expiratory/inspiratory airflow duration; numbers ofinspiration and inspiratory airflow duration; expiratory and inspiratory volume. These results show that whispered speechneeds more respiratory effort but shows poorer aerodynamic efficacy during phonation than normal speech.
