RL-TR-95-257, FINAL TECHNICAL REPORT: COMMUNICATIONS CHANNEL NORMALIZATION TECHNIQUES (DEC-1995)

RL-TR-95-257, FINAL TECHNICAL REPORT: COMMUNICATIONS CHANNEL NORMALIZATION TECHNIQUES (DEC-1995)., Performance of Speech and Speaker recognition systems generally degrade when there is a mismatch between training and testing conditions. A significant part of the mismatch is caused by the differences in transmission channels and transducers. This report describes a new methodology for extracting robust features based on systematic selection and filering of the eigenmodes.
