Intelligibility assessment of a multi-band speech enhancement scheme
Amir Hussain · 2002
A series of psychoacoustic experiments are described which attempt to assess the capability of a multi-microphone sub-band adaptive (MMSBA) signal processing scheme for improving the intelligibility of speech corrupted with recorded automobile noise. For the experimental cases considered, the proposed MMSBA scheme employing diverse sub-band processing is shown to deliver a statistically significant improvement in terms of both speech intelligibility and perceived quality when compared with both the wideband processed and the noisy unprocessed case.
