Latest Patents
Azhar Mustapha holds a patent for an "Adaptive post-filtering technique based on the Modified Yule-Walker filter." This adaptive time-domain post-filtering technique addresses the issue of spectral tilt in speech spectrum. The technique can be applied to various speech coders, ensuring a flat frequency response at the formant peaks of the speech spectrum. By gathering information about the relationship between poles and formants, he estimates the formants and their bandwidths. This information is then utilized to design the modified Yule-Walker filter based on a least squares fit in the time domain.
