A system for recognizing physiological sound comprises a receiving module, a feature extracting module, a classifier, and a comparing module. A method for recognizing physiological sound comprises receiving a physiological sound by the receiving module； extracting at least one feature from the physiological sound by the feature extraction module； classifying the at least one feature to identify at least one category by a classifier； and comparing the at least one category with a normal physiological sound and/or an abnormal physiological sound by the comparing module for evaluating a risk of disease. The method and system for recognizing physiological sound can precisely identify the specific physiological sound and exclude the noise.一種識別生理聲音的系統包括接收模組，特徵識別模組，分類器以及比較模組。一種識別生理聲音的方法包括一接收生理聲音的接收模組；用於提取至少一種生理聲音的特徵識別模組；分類至少一特徵同時識別至少一種種類的分類器；使用比較模組對比正常生理聲音以及異常生理聲音中至少一種類別以評估疾病風險。上述識別生理聲音的方法以及系統可以精確地識別特殊的生理聲音同時排除雜訊。
