Latest Patents

Seung-Yun Kim holds a patent for an "Online target-speech extraction method based on auxiliary function for robust automatic speech recognition." This patent outlines a method for extracting target speech signals, which includes several key steps. The process involves receiving information on the direction of arrival of the target speech source relative to the microphones. It also includes generating a nullformer to remove the target speech signal from input signals and estimate noise. The method further sets a real output of the target speech source using an adaptive vector and establishes a dummy output through the nullformer. Additionally, it sets a cost function to minimize dependency between the real and dummy outputs using independent component analysis or independent vector analysis. Finally, the target speech signal is estimated using the cost function and an auxiliary function.
