AUDITORY-PERCEPTUAL IDENTIFICATION OF VOICE QUALITY BY EXPERT AND NON-EXPERT LISTENERS*

In a perception task 13 types of voice quality were to be identified by two listener groups. Expert listeners with a professional background in forensic phonetics performed significantly better than the non-expert group. Furthermore, the non-experts produced more heterogeneous types of error. For prominent types of voice quality and stimuli with a strong scalar degree low error rates were observed for the experts.
