Latest Patents

One of his latest patents is titled "Recognition confidence measuring by lexical distance between candidates." This invention provides a method, medium, and system that can more accurately determine whether an input speech signal is in-vocabulary. It achieves this by extracting an optimum number of candidates that match a phone string extracted from the input speech signal and estimating a lexical distance between the extracted candidates. The method includes extracting a phoneme string from a feature vector of an input speech signal, matching it with phoneme strings of vocabularies registered in a predetermined dictionary, and determining whether the input speech signal is in-vocabulary based on the lexical distance.

Another significant patent is the "Apparatus and method of reducing noise by controlling signal to noise ratio-dependent suppression rate." This invention is designed to reduce noise signals in speech recognition systems. The apparatus estimates a signal-to-noise ratio for each frequency band of the speech signal, applies a noise suppression rate based on the estimated signal-to-noise ratio, and effectively reduces the noise signal of the speech signal.
