摘要： A voice recognition system applies speaker-dependent modification functions to acoustic feature vectors prior to voice recognition pattern matching against a speaker-independent acoustic model. An adaptation engine matches a set of acoustic feature vectors X with an adaptation model to select a speaker-dependent feature vector modification function f( ), which is then applied to X to form a modified set of acoustic feature vectors f(X). Voice recognition is then performed by correlating the modified acoustic feature vectors f(X) with a speaker-independent acoustic model.

摘要： Video encoding techniques are described. In one example, a video encoding technique includes identifying a pixel location associated with a video block in a search space based on motion vectors associated with a set of video blocks within a video frame to be encoded, wherein the video blocks in the set are spatially located at defined locations relative to a current video block of the video frame to be encoded. A motion estimation routine can then be initialized for the current video block at the identified pixel location. By identifying a pixel location associated with a video block in a search space based on motion vectors associated with a set of video blocks within a video frame, the phenomenon of spatial redundancy can be more readily exploited to accelerate and improve the encoding process.

摘要： Generally stated a method and an accompanying apparatus provides for a voice recognition system (300) with programmable front end processing unit (400). The front end processing unit (400) requests and receives different configuration files at different times for processing voice data in the voice recognition system (300). The configuration files are communicated to the front end unit via a communication link (310) for configuring the front end processing unit (400). A microprocessor may provide the front end configuration files on the communication link at different times.
