Latest Patents
Ching Elizabeth Ho holds a patent for a speech processing technique designed for use in speech recognition and speech coding. This technique focuses on obtaining an intermediate set of frequency-dependent features from a speech signal. It utilizes multiple tapers derived from Slepian sequences to create a product of the speech signal and the Slepian functions. The method involves obtaining multiple tapered Fourier transforms from this product, which are then used to calculate the frequency-dependent features. In one preferred embodiment, a derivative of the cepstrum of the speech signal serves as an estimate of the speech signal pitch. Additionally, the F-spectrum is calculated from the product, and the F-cepstrum is derived by calculating the Fourier transform of the smoothed derivative of the log of the F-spectrum. The maximum of the F-cepstrum also provides a pitch estimation.
