Speech Intelligibility Index (SII) is a model that predicts speech intelligibility based on a person’s hearing thresholds and audible speech cues in given frequency bands. The SII is able to predict how loss of audibility due to hearing loss affects intelligibility of speech. Thus, the SII has been applied clinically in evaluation and fitting for hearing aids to quantify how much audibility is compensated by amplification. Although the SII known as Articulation Index was first introduced during the 20th century, calculation methods and aspects of the SII have been continually refined and developed for clinical use. This article provides (1) a brief history of the SII, (2) a view of components and calculation methods of the SII, (3) a review of applications for clinical use, and (4) a discussion of limitations and aspects that need to be considered for clinical applications in future.
Abstract
Speech Intelligibility Index (SII) is a model that predicts speech intelligibility based on a person’s hearing thresholds and audible speech cues in given frequency bands. The SII is able to predict how loss of audibility due to hearing loss affects intelligibility of speech. Thus, the SII has been applied clinically in evaluation and fitting for hearing aids to quantify how much audibility is compensated by amplification. Although the SII known as Articulation Index was first introduced during the 20th century, calculation methods and aspects of the SII have been continually refined and developed for clinical use. This article provides (1) a brief history of the SII, (2) a view of components and calculation methods of the SII, (3) a review of applications for clinical use, and (4) a discussion of limitations and aspects that need to be considered for clinical applications in future.
