Vocal Function Exercises (VFE) is a voice therapy program which uses a vowel /o/ with buzzy sound that is produced with the tightly constricted lips. Clinical studies have shown efficacy of the program with normal and pathologic voices. Use of the sound may have contributed to the improvement of the voices; however, its mechanism has not been examined. The present study examined acoustic and physiologic characteristics of /o/ with and without buzz. Sound and visual recording of both sounds were obtained from four voice pathologists who have been trained to provide VFE. A questionnaire was used to examine how the participants perceive physiologic and acoustic characteristics of /o/ with buzz. Visual analysis revealed a difference between the two productions with two participants. Acoustic analysis revealed unique profile of /o/ with buzz. The subjects’ description was consistent in lip positioning and the presence of sympathetic vibration at their lips.
