A new acoustic parameter for the description of hoarseness has been developed: The Glottal-to-Noise Excitation Factor (GNR-Factor). It shows to which extend a voice is excited by turbulent noise on a vocal-tract constriction or by vocal-fold vibration. The new parameter is introduced briefly. Then the independence of this parameter from other well-known roughness parameters is demonstrated by multidimensional data analysis.
