THE DESIGN AND APPLICATION OF SPEECH RECOGNITION MODULE

Ming-Ying Chen Chun-Liang Lo

Department of Electronic Engineering Yungta Institute of Technology and Commerce

Pingtung, Taiwan 909, R.O.C.

Key Words: single-chip 8051, speech recognition, serial communication, infrared control.

ABSTRACT

The technology of speech recognition has become mature and some effective methods have been proposed. In this paper, we propose the use of a speech recognition chip to develop a stand-alone speech recognition module and create the design interface for an application program. In this framework, the concept of serial communication will be used to develop a control mechanism. It will be suitable for designing various hardware platforms. Single-chips or PCs can be used to control the module. Finally, we implement a discrete word speaker-dependent recognition system and program development platform. In research for applications using speech recognition modules, we have focused on three selected applications of speech recognition: voice dialers, voice-activated toys, and voice-activated home appliances. We have developed a technology of code conversion for the infrared control. We can control toys or home appliances with an infrared interface via the recognition module. It has been proved in experiments that the module works well in speaker-dependent situations.

The test results are stable and excellent in normal conditions.
