Abstract

Method and system for real-time speech recognition is provided. The speech algorithm runs on a platform having an input-output processor and a plurality of processor units. The processor units operate substantially in parallel or sequentially to perform feature extraction and pattern matching. While the input-output processor creates a frame, the processor units execute the feature extraction and the pattern matching. Shared memory is provided for supporting the parallel operation.
