Re: Convolutive feature extraction (Searching for papers)
I wrote these papers that probably describe what you want:
Also look up Tuomas Virtanen's papers on convolutive NMF. There are
also some 2D extensions by Schmidt & Morup and by Fitzgerald which
are best suited for finding features on constant-q spectra.

Recently, I started to look into extracting dynamic speech features
from multiple frames(convolutive feature).
For example, as a input vector of HMM, the delta and delta-delta of
mfcc is computed from cepstrum which is extracted from single frame.
Contrary to this approach, convolutive feature is trying to extract
features from multiple frames at one time.
Firstly,I was searching recent papers using 'speech, dynamic,
convolutive, multi frame, feature, etc' as a keyword.
But I couldn't find papers related to that field. It was hard to
find out how much work was done on this field.
Would you please help me to find recent work(maybe a paper) with
multi-frame features in speech?
I'd love to hear some advices from you.
