    Abstract: An elevator fault diagnosis method based on Sequential Probability Ratio Test (SPRT) is proposed in this paper. In order to verify the effectiveness of the method, this paper designed the fault diagnosis experiment for elevator mechanical system. Firstly, the wavelet transformation is used to filter the noise of the vibration signal collected in th... Show More

    Abstract: This paper considers suprasegmental parameters such as intonation, stress and speech rhythm. Correct articulation of sounds and correct pronunciation in the target language depend on prosodic structures presented by standard intonation patterns. Linguistic and acoustic resources provide the basis for computer-aided intonation training in and outsid... Show More
