| ABSTRACT |
|
The purpose of this study was to investigate the effects of filtered noises in discriminating “Gom /Gong” under the given SNR conditions
and to identify the contributions from BMLD with various phase conditions trough the revised analysis on the current data set. The
results showed that the effects of the low pass filtered noise at 1 kHz cutoff frequency on word discrimination was statistically significant
at the SNR level of -10 dB (paired-t test, df=9, t=2.168, 1-tailed, p<0.05). Further studies should focus on detailed mechanisms
of filtered noises and BMLD in word discrimination to provide useful information in developing speech signal processing of
assistive listening devices. |
