Determining audio signatures for active noise control

Abstract

Many speech intelligibility (SI) assessors are now available for evaluating SI in room. However, these assessors are all using English or Western background word lists. The purpose of this study is to determine the audio signatures of the selected Bahasa Melayu (BM) words for development of SI assessors using BM words between monosyllable and disyllable. Monosyllable and disyllable words of BM words had been used to obtain audio signatures, so that characteristics in terms of amplitude and frequency of the words can be established. The anechoic room and reverberation room will be used for recording and listening of these selected BM words. Matlab software had been used to process these word signals.
