    摘要: A buffer circuit with slow output edges is described. Pulsed higher value currents are driven from one shot timing circuits to inject a pulse of current into the control gate of the buffer's output MOSFET to speed up the beginning of the turning on or the turning off of the output MOSFT. When the beginning and turning on and off is reached lower value current sources continue to drive the gate of the output MOSFET. In one embodiment, one shots are triggered from the rising and falling edges of the input signal. The effect of the higher value current pulses is to reduce the circuit delay through the buffer. Also, the pulse width can be designed as temperature sensitive, and supply voltage sensitive so as to maintain the buffer circuit delay as substantially constant as temperature, supply voltage and process variation occur.

    摘要: Embodiments are disclosed that relate to the use of identity information to help avoid the occurrence of false positive speech recognition events in a speech recognition system. One embodiment provides a method comprising receiving speech recognition data comprising a recognized speech segment, acoustic locational data related to a location of origin of the recognized speech segment as determined via signals from the microphone array, and confidence data comprising a recognition confidence value, and also receiving image data comprising visual locational information related to a location of each person in an image. The acoustic locational data is compared to the visual locational data to determine whether the recognized speech segment originated from a person in the field of view of the image sensor, and the confidence data is adjusted depending on this determination.
