Abstract
The present study attempted to study perception of time-compressed speech and the effect of compression ratio for phonemically balanced (PB) word lists in Kannada and monosyllables. The test was administered on 30 normal hearing individuals at compression ratios of 40%, 50%, 60%, 70% and 80% for PB words in Kannada and monosyllables.The results of the study showed that the speech identification scores for time-compressed speech reduced with increase in compression ratio. The scores were better for monosyllables compared to PB words especially at higher compression ratios. The study provides speech identification scores at different compression ratio for PB words and monosyllables in individuals with normal hearing. The results of the study also showed that the scores did not vary across gender for all the compression ratios for both the stimuli. The same test material needs to be compared the clinical population with central auditory processing disorder for clinical validation of the present results.

Summary
(PB) word lists in Kannada and monosyllables. The test was adminis- tion; auditory pattern recognition; audition in temporal aspects; auditered on 30 normal hearing individuals at compression ratios of 40%, tory performance in competing acoustic signals; and auditory perform-. 50%, 60%, 70% and 80% for PB words in Kannada and monosyllables. The results of the study showed that the speech identification ly scores for time-compressed speech reduced with increase in compression ratio. The scores were better for monosyllables compared to PB n words especially at higher compression ratios. The study provides o speech identification scores at different compression ratio for PB words and monosyllables in individuals with normal hearing. The e results of the study showed that the scores did not vary across gens der for all the compression ratios for both the stimuli.
