Title Intelligent Control System Based on Speech Recognition
Abstract
Speech recognition technology is an important application of speech signal processing technology and the key to realize voice-controlled technology. Nowadays the Human-Computer Interaction of natural voice is the hot and difficult point in speech recognition research fields. This paper introduces the design of the intelligent voice-controlled system based on the LD3320 chip designed by ICRoute company and the STC10L08XE MCU. It also tells how to realize the function of requesting songs and displaying 8×8 LED with this system and the experimental result turned out to be wonderful.
Firstly, the paper introduces the speech recognition technology about the basic concepts, related theories, development and current situation. Then, it presents the basic function, hardware structure and drive means of LD3320. The structure of the system and the hardware and software design of MCU module have been related in detail. After slight alteration, the system could be applied to intelligent guides, homes, and various kinds of electronic products, etc. It has immense potential and a brilliant future in the application field.
