    摘要: An integrated circuit (IC), comprises a receiver on an IC substrate. The receiver is configured to receive a stressed input signal. A built in self test (BIST) circuit is provided on the IC substrate for testing the receiver. The BIST circuit comprises an encoder configured for receiving an input signal and identifying whether a first condition is present, in which two or more consecutive input data bits have the same polarity as each other. An output driver circuit provides the stressed input signal corresponding to the two or more consecutive input data bits. The stressed input signal has an amplitude that is larger when the encoder identifies that the first condition is present and smaller when the encoder identifies that two or more consecutive input data bits have different polarity from each other.

    摘要: The present invention provides a method and apparatus for detecting speech spectral peaks and a speech recognition method and system. The method for detecting speech spectral peaks comprises detecting speech spectral peak candidates from power spectrum of the speech, and removing noise peaks from the speech spectral peak candidates according to peak duration and/or peak positions of adjacent frames, to detect speech spectral peaks. In the present invention, reliable speech spectral peaks can be obtained by removing noise peaks using the limitations of peak duration and adjacent frames in the detection of the speech spectral peaks. Further the energy values of the speech spectral peaks are used to extract the MFCC feature of speech instead of a sample sequence of the whole power spectrum in the conventional technique, the noise robustness of speech recognition can be enhanced while not increasing the speech feature dimensions.
