    摘要: A method and apparatus for detecting end points of speech activity in an input signal using spectral representation vectors performs beginning point detection using spectral representation vectors for the spectrum of each sample of the input signal and a spectral representation vector for the steady state portion of the input signal. The beginning point of speech is detected when the spectrum diverges from the steady state portion of the input signal. Once the beginning point has been detected, the spectral representation vectors of the input signal are used to determine the ending point of the sound in the signal. The ending point of speech is detected when the spectrum converges towards the steady state portion of the input signal. After both the beginning and ending of the sound are detected, vector quantization distortion can be used to classify the sound as speech or noise.

    摘要: A method and apparatus for detecting speech activity in an input signal. The present invention includes performing begin point detection using power/zero crossing. Once the begin point has been detected, the present invention uses the cepstrum of the input signal to determine the endpoint of the sound in the signal. After both the beginning and ending of the sound are detected, the present invention uses vector quantization distortion to classify the sound as speech or noise.

    摘要: Disclosed herein is a system for determining communication paths, especially for AV/C devices. The system includes gathering pertinent information about drivers in each available communication between nodes in the system and ordering the driver information in a communication path list string. The system may be employed with multiple nodes having one or more communication paths between nodes. The system may also be employed with multiple nodes where at least one of the nodes is a bridge.

    摘要: Disclosed herein is an automatic ID allocation technique for use in AV/C device applications. The method allows ID assignment without manual user intervention. The method includes assigning an ID to an entity when called to do so upon detection of a new entity. Furthermore, old IDs are reallocated for later use upon disconnection of the associated entity.
