Design of Speech Recognition Co-Processor with Fast Gaussian Likelihood Computation

摘要：

This paper presents the design of high performance co-processor used to calculate the posterior probabilities for the embedded speech recognition of CHMM (Continuous Hidden Markov Model) with the MPIE (Maximum Probability Increase Estimation) algorithm to finish the most computation intensive operations in the speech recognition flow. The design of the coprocessor is verified on Xilinx FPGA platform with ARM as MCU.
