Abstract :
This paper presents the FPGA implementation of an ASR system in a car environment. The voice feature vectors are extracted by using Mel-Frequency Cepstral Coefficients and compared by using FastDTW algorithms. The recognition rate of the proposed system is 81.5%. Both MFCC and FastDTW algorithms are implemented by Verilog HDL. The target device is chosen as Altera DE2-115.
