How to discriminate speech from nonspeech ?
I am trying to use independent component analysis (ICA) with data
from two microphones to separate two sound sources. One source is
speech and the other source is background noise such as bombing sound.
However, ICA can not decide which output is speech dominant and which
output is noise dominant.
Is there any algorithm which can distinguish speech from nonspeech
or determine which output from ICA is speech-dominant ?
I found some papers such as the one shown as below, but it seems
