Design of Wireless Intelligent Speech Control System Based on DSP and ZigBee

Introduce a Wireless Intelligent Speech Control System based on DSP as Speech Control Model and PIC Microcontroller & wireless transmit chip CC2420 as the ZigBee Wireless Transmit Model. Hardware design, Speech Recognition Algorithm and Program design are given in this paper. Especially Speech Recognition Algorithm is optimized toward DSP and ZigBee Protocol Stack is reduced. Independent, high recognition rate and convenient operation family intelligent speech control system is realized in our system.
