In our previous work \cite{icassp2008}, we showed that combination of classifiers trained on different ranges of {\it modulation} frequencies is more effective if performed in sequential (hierarchical) fashion. In this work we verify that combination of classifiers trained on different ranges of {\it auditory} frequencies is more effective if performed in parallel fashion. Furthermore we propose an architecture based on neural networks for combining evidence coming from different auditory-modulation frequency sub-bands that takes advantages of previous findings. This reduces the final WER by 6.2\\% (from 45.8\\% to 39.6\\%) w.r.t the single classifier approach in a LVCSR task.}, pdf = {https://publications.idiap.ch/attachments/reports/2008/valente-idiap-rr-08-12.pdf}, postscript = {ftp://ftp.idiap.ch/pub/reports/2008/valente-idiap-rr-08-12.ps.gz}, ipdmembership={speech}, }
