Short Content: Abstract: This article proposed based on the TMS320VC5402 speech recognition system plan. The overall system as the core electric circuit carries on the design take TMS320VC5402, carries on A/D by TLC320AD50C to transform, by the TMS320VC5402 recognition voice signal, then and the robot correspondence, and controls the LCD demonstration recognition result by AT89S52. Key word: DSP; A/d conversion; Monolithic integrated circuit; Isolated word; Speech recognition 1 introduction Develops unceasingly along with the voice signal processing technology and ...

Short Content: Introduction The traditional smoke eye generally by the smog sensor and the smog survey chip constitution, the survey chip receive sensor signal and carries on processing, thus judges whether to have the fire to occur. This kind of smog detector structure is simple, the cost is low, but has the rate of false alarm to be high and environment adaptiveness bad shortcoming. In order to solve this problem, the monolithic integrated circuit is inserted to the alarm apparatus, distinguishes the ...
