Dennis L Wilson, James L Wayman: Signal detector employing mean energy and variance of energy content comparison for noise detection. Loral Aerospace, Perman & Green, June 21, 1994: US05323337 (139 worldwide citation)

A signal detector discriminates between signals manifesting noise and signals manifesting information, both of which appear at an input. A analog-to-digital converter circuit samples the signals and a Fourier filter determines, for each signal sample, energy content of each of a plurality of frequen ...

Dennis L Wilson, James L Wayman: Low bit rate voice transmission for use in a noisy environment. Loral Aerospace Corporation, Perman & Green, October 4, 1994: US05353374 (101 worldwide citation)

A compressing a voice signal by the steps of (a) digitizing an input signal that includes a voice signal, the input signal including a coherent noise component; and (b) compressing the digitized voice signal with a synchronized overlap add processor (20). So as to prevent the synchronized overlap ad ...

Dennis L Wilson, James L Wayman, John Zugel: Continuous speech voice transcription. December 3, 2002: US06490561 (51 worldwide citation)

A method and apparatus that provide for automatic speech transcription that may be used transcribe structured reports. The method and apparatus provide for speaker dependent, continuous speech recognition using a limited vocabulary. Transcription is based on recognition of a vocabulary of sounds fol ...

Dennis L Wilson, James L Wayman: Synchronized overlap add voice processing using windows and one bit correlators. Lockheed Martin Corporation, Kenneth W Float, January 9, 2001: US06173255 (38 worldwide citation)

Apparatus and methods for compressing an audio signal. An analog to digital converter is used to digitize the audio signal. A linear predictor processes the digitized audio signal to attenuate coherent noise and produce a residual output signal that is representative of the audio signal. An improved ...
