Abstract: One of the main aims of Ambient Intelligence(AmI) is to make human interaction with the environment more natural. The concept of natural human machine interaction in AmI is embodied through speech recognition technology. In order to ensure the real-time of the interaction, the system implements the algorithms by using IP core technology. The experimental result shows that the system performs well and it is helpful for the application research of speech recognition technology in AmI.

Key words: Ambient Intelligence(AmI), speech recognition, embedded, Hidden Markov Model(HMM), IP core
