| Abstract | One concept of speech recognition is that the human utterance always contains
statistical information, in which can be modeled by applying powerful mathematics. By using
Hidden Markov Model approach, the speech recognition system has been implemented
successfully. However, the incoming speech signal must be analyzed in the first step before
going to any processing. The spectral analysis and the vector quantization methodology are
selected for this purpose.
Although in the first step, the speech recognition system is implemented properly in
software programming but the goal of this thesis is to design an embedded chip that is more
useful in the current market. Finally, by using VHDL and EDA tools, the speech recognition
is implemented completely on FPGA with recognition efficiency of 92%. The system is
speaker-dependent and has a vocabulary containing 52 Thai words as case study.
