Speech recognition system having an interface to a host computer bus for direct access to the host memory
 A signal processing card packaged on a bus of a personal computer has a bus master which is used to access the main memory of the personal computer. A large table of probability values required for speech recognition is held in the main memory. When a label to be processed is generated, only the necessary part of the table is read from the main memory to the memory on the signal processing card by direct memory access transfer to perform speech recognition processing.
