| ABSTRACT |
|
It is well known that assessment of speech perception is one of essential elements in audiology including its
research and clinical practices. Numerous researchers have attempted to develop and evaluate the speech perception
assessment materials in order to give appropriate intervention and better treatment to hearing-impaired listeners. One
of primary goals of this paper is to review the Korean Speech Audiometry (KSA) (Lee et al., 2010) in terms of its
development and standardization, and thus to increase awareness among professionals about its strengths and
weakness related to the assessment of speech perception performance in adults and children with normal hearing and
those with hearing loss. This paper includes reviews of three speech perception tests, e.g., Word Recognition Score
(WRS), Speech Recognition Threshold (SRT), and Sentences Recognition Score (SRS), which have a small set of
experiments and outputs based on two requirements of the speech perception assessment, called validity and
reliability. The WRS showed an inter-list difference up to 20% in 25 subjects with moderate sensorineural hearing
loss even if there was no significant difference statistically among lists. In SRT, there were spondees having unequal
sound pressure levels and several tense (or fortis) sounds in the lists. Lists of the SRS showed a ceiling effect in
either the normal hearing or the hearing-impaired listeners in spite of a good validity. The authors expect that
audiologists will have a new insight and intuition on the speech perception tests after reading this review paper.
Also, the authors ask the audiologists to know that developing and evaluating the KSA is an on-going process and
it will continue to be developed in the future. |
