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. |
