Research On Mobile Robot Remote Control System Based On Speech Recognition

Speech recognition and remote control is the major areas of study in the field of the mobilerobot. With the development of the computer and artificial intelligence, the robot is high demandin people’s life. Speech can be achieved free communication with the robot. Remote controlsystem can trans-regional operate the robot. Based on Speech recognition technology, a remoterobot control system is designed and realized, the mainly work as follows:First of all, the development of speech recognition technology and remote controltechnology is introduced. Both domestic and foreign research status, research methods andsummarized the advantages and disadvantages of each method, and laid an important foundationfor this study.Secondly, describes the basic process of voice processing. In the field of time-domainspeech signal pre-processing, windowed framing, endpoint detection and feature extraction areanalysed，and the Hidden Markov Model for speech recognition algorithm is followed;Then, create intelligent robot remote control system hardware platform based on speechrecognition. Details of the system’s hardware, robot kinematics modeling, the last and the keytechnical requirements;Finally, with the Visual Studio2003.NET software development platform, the mobile robotremote speech recognition system is programmed based on VC++language. the mobile robotremote control system speech recognition-based is verified by experiments.
