Abstract
In this paper, a forward/backward adaptive digital filtering method is studied for the enhancement of noisy speech. The enhancing algorithm uses future samples as well as previous samples to estimate a current sample, and utilizes the correlational property of speech. It is effective for the enhancement of narrow-band as well as wide-band noisy speech. To improve the enhancing capability further, its modified version is also considered. This modified algorithm, of which structure is relatively simple, works for any kind of additive noise, and results in signal-to-noise ratio gain over existing enhancement algorithms by about 2 dB.Keywords
