Perceptual and automatic evaluations of the intelligibility of speech degraded by noise induced hearing loss simulation This study aims at comparing perceptual and automatic intelligibility measures on degraded speech. It follows a previous study that proposed an approach for the simulation and automatic evaluation of the effect of age-related hearing loss (presbycusis) on speech intelligibility. In this work, we propose to adapt this approach to a different hearing disorder : noise induced hearing loss (hearing loss caused by trauma in the professional context). Thus, a speech corpora simulating different levels of noise induced hearing loss is proposed and used to study perceptual and automatic intelligibility measures. The perceptual evaluation showed similar effects of the hearing disorder on the male, female and child speakers intelligibility. Also, the automatic intelligibility measure (based on automatic speech recognition scores) is proved to well represent the effects of the different severity levels of the hearing disorder. Indeed, high correlation measure are computed between the automatic and perceptual intelligibility measures.
