Abstract:
OBJECTIVE:The objective of the study was to determine the speech perception abilities for spectrally modified speech signals in individuals with auditory dys-synchrony. STUDY SAMPLE:The speech identification scores of 30 normal hearing and 12 individuals diagnosed as having auditory dys-synchrony were studied. DESIGN:Phonemically balanced words in Kannada developed by Yathiraj and Vijayalakshmi (2005) were presented unfiltered and filtered at 1700 Hz low-pass and 1700 Hz high-pass cut-off frequencies, and speech identification performance was assessed. RESULTS:Results revealed that there is a highly significant difference in speech identification scores for unfiltered and low-pass filtered words. This difference could be attributed to the physiological coding deficits of low frequency information which are usually coded by phase locked responses in auditory nerve fibers ( Sek & Moore, 1995 ). CONCLUSIONS:Thus, low-pass filtered words can be used as an effective tool to identify individuals with auditory dys-synchrony, especially those who have good speech identification scores in quiet.
