Latest Patents
Schaefer holds a patent for a signal conditioning apparatus. This invention is designed to condition a human voice signal for input to a time-domain voice recognition system. The signal conditioner normalizes sampled human voice inputs, ensuring that all inputs yield an output with substantially the same pitch and frequency bandwidth characteristics. The apparatus includes a pitch altering circuit that modifies the pitch of the input human voice signal and a frequency band limiting circuit that restricts the range of spectral information contained in a signal. The pitch altering circuit converts the input into a digital signal at a first conversion rate and then converts the digital signal back to an analog signal at a second rate, which is unequal to the first rate. The frequency band limit circuit consists of multiple filters at different points in the frequency spectrum. Schaefer's innovative work has resulted in 1 patent.
