ABSTRACT:
A computer-readable medium stores sequences of instructions to be executed by a processor. These instructions cause the processor to perform the following steps to enhance 3-D localization of a speech source. A digital speech signal is received. The maximum frequency of the digital speech signal is determined. The sampling rate of the digital speech signal is increased. Next, wide-band Gaussian noise is added to the digital speech signal to create a wide-band digital speech signal with higher frequencies. Finally, the wide-band digital speech signal can be localized via an FIR (finite impulse response) filter.
