Latest Patents

Uihyeop Shin's latest patents include innovative methods for online target-speech extraction. One of his patents describes a target speech signal extraction method that initializes a steering vector for a target speech source and an adaptive vector. This method sets a real output channel of the target speech source as an output by the adaptive vector, while also initializing adaptive vectors for noise. The process involves minimizing dependency between the real output for the target speech source and a dummy output for the noise. The auxiliary function is utilized to update the adaptive vectors, ultimately estimating the target speech signal from the input signals.

Another patent focuses on receiving information regarding the direction of arrival of the target speech source relative to the microphones. This method generates a nullformer to remove the target speech signal from the input signals and estimate noise. It sets a real output of the target speech source using an adaptive vector and establishes a dummy output by the nullformer. The cost function is designed to minimize dependency between the real and dummy outputs, employing independent component analysis (ICA) or independent vector analysis (IVA) for enhanced accuracy.
