This paper analyzes differences and commonality in pathological voice quality evaluation between two different scaling systems, GRBASI and RASATI. The results identified significant interrelations between the scales. Harshness, included in RASATI, is described as noisiness and strain in the GRBASI scale. Roughness is found to be the most consistent factor and easiest to identify by listeners of different linguistic backgrounds. Intercultural agreement in pathological voice quality evaluation seems to be possible.
