Latest Patents
One of Chan-Woo Kim's latest patents is a formants extracting method that combines spectral peak picking and roots extraction. This innovative method allows for the precise identification of formants, which are resonance frequencies of voice, while minimizing computational complexity. The technique involves searching for maximum values using a spectral peak-picking method and analyzing pertinent roots when the number of formants is determined to be two. This analysis is performed by applying Cauchy's integral formula in a z-domain, ensuring efficiency in the process.
Another notable patent is a speech distinction method. This method divides an input voice signal into multiple frames and extracts parameters from these frames. It models a probability density function of a feature vector for each frame and calculates the probabilities of whether a frame is a noise frame or a speech frame. A hypothesis test is then conducted to classify the frames accurately based on the obtained probabilities.
