It shows to which extend a voice is excited by turbulent noise on a vocaltract constriction or by vocal-fold vibration. The new parameter is introduced brie y. Then the independence of this parameter from other well-known roughness parameters is demonstrated by multidimensional data analysis.

متن کاملImmediate effects of vocal warm-up exercises on elementary teachers' voice
Introduction: Teachers are a large group of professional voice users who are exposed to many voice problems. Vocal warm-up exercises (VWUE) can prepare the muscles involved in vocalization before teaching and can reduce voice damage in teachers. However, limited studies have examined the effects of VWUE on teachers' voices. Therefore, the present study was conducted to investigate the immediate...
