Facial Bone Vibration In Resonant Voice Production

摘要

Summary: Purpose. This study investigated whether resonant voice training would enhance facial bone vibration during resonant voice production.Methods. Twelve normal healthy participants undertook four sessions of resonant voice training, each lasted for 30 minutes. Piezoelectric accelerometer was used to measure the vibratory level on the face (nasal bridge and upper lip) and the perilaryngeal area during the production of nasal consonant /m/ and vowels /a/, HI, and /u/ before and after the resonant voice training. The extents of vibration of these four sounds among these three sites were compared.
