Purpose: Subjective measurements, such as speech audiometry, are essential to determine the perception of speech as it provides insight regarding perceptual abilities. The present study aimed to develop paired word test stimuli in Tamil and evaluate their utility for assessing the benefits of a hearing aid. Methods: The stimuli were 30 paired words which were paired to rhythm containing almost all vowels and consonants of the Tamil language differing in one or more distinctive features, such as place, manner, voicing features of consonants, and height, duration, and rounding features of vowels. The paired words test was administered to 60 participants with normal hearing and 60 participants with hearing impairment. The correct identification scores and their percentage were computed to notice the benefit provided by their hearing aids. Results: The overall performance of individuals with normal hearing on the paired identification was high, suggesting that these paired word test materials could be used for individuals with hearing impairment to assess hearing aid benefit. A greater improvement in recognition scores for paired words was obtained after being fitted with a hearing aid in individuals with hearing impairment. It was noticed that due to hearing loss, the audibility of perception reduces, yielding lower scores in paired word identification. Conclusion: When the proper fitting was done, the percentage of identification scores was increased. Therefore, the present study concludes that speech perception abilities can be evaluated and quantified using these paired word tests.
