To provide a noise suppression method in speech recognition which does not require to estimate a parameter of a speech model from a speech signal in advance and which can realize speech recognition with high accuracy, when noise fluctuation does not depend on the Gaussian distribution and the amount of statistics of noise is unknown, that is, even under a real environment where the speech model is unknown.例文帳に追加

音声モデルのパラメータを音声信号から事前に推定する必要がなく、また、雑音変動がガウス分布に依存せずに、雑音の統計量が未知の場合、すなわち、音声モデルが未知である実環境下においても正確度の高い音声認識を可能とする音声認識における雑音抑制方法を提供する。 - 特許庁
