Latest Patents

Among his latest innovations is a patented technology for noise reduction in speech recognition within moving vehicles. This sophisticated system incorporates a speed level classifier that measures the speed of a moving object using noise signals to classify speed levels. It features dual speech enhancement units: the first leverages a Wiener filter to improve sound quality at lower speeds, while the second utilizes a Gaussian mixture model for higher speeds. Additionally, it includes an endpoint detection unit for identifying start and end points of speech, along with an elimination unit that removes sudden noise components based on a sudden noise Gaussian mixture model.

Another notable patent developed by Ki-young Park is an utterance verification method and apparatus designed for isolated word N-best recognition results. This method involves calculating log likelihoods of context-dependent phonemes and anti-phonemes based on an N-best speech recognition result. By measuring a confidence score and the distance between phonemes, the system effectively compares these parameters against predefined thresholds to determine the acceptance of the recognized word.
