| Abstract: | The features of voice-character parameters and fundamental speaker recognition methods are analyzed by using linear prediction cepstrum coefficient and hidden Markov model as modeling algorithms. The speech recognition control function is implemented by the hardware platform Sunplus MCU .The experimental results show that the designed system has high identity precision can achieve the request of safety-secrecy. |
