【 摘 要 】

A device for speech command recognition is designed and implemented in this paper. The adaptive filtering technique is adopted for speech enhancement by using two microphones for sampling the background noise and noisy speech signal correspondently. The connected-word speech recognition algorithm based on HMM is employed for speech command recognition. The experiment shows that the equipment can work well under the background noise of 90dB.
