BLIND SEPARATION OF DELAYED SOURCES BASED ON INFORMATION MAXIMIZATION Kari Torkkola Motorola, Inc., Phoenix Corporate Research Laboratories, 2100 E. Elliot Rd, MD EL508, Tempe, AZ 85284, USA tel: (602)413-4129, fax: (602)413-5934, email: [email protected] ABSTRACT Recently, Bell and Sejnowski have presented an approach to blind source separation based on the information maximization principle. We extend this approach into more general cases where the sources may have been delayed with respect to each other. We present a network architecture capable of coping with such sources, and we derive the adaptation equations for the delays and the weights in the network by maximizing the information transferred through the network. Examples using wideband sources such as speech are presented to illustrate the algorithm.

Mach1 for Nonuniform Time-scale Modification of Speech: Theory, Technique, and Comparisons

We propose a new approach to nonuniform time compression, called Mach1, designed to mimic the natural timing of fast speech. At identical overall compression rates, listener comprehension for Mach1-compressed speech increased between 5 and 31 percentage points 2 over that for linearly compressed speech, and response times dropped by 15%. For rates between 2.5 and 4.2 times real time, there was ...
