Electric Car Design, Based On Voice Control

As science and technology and human living standards, the use of voice recognition technology to design and manufacture a variety of consumer electronic products and electrical equipment, is the inevitable trend of social development. What is speech recognition technology does! Simply put, that is, electronic devices or computer equipment can understand people saying, and understand it, and make a correct reflection of, or to implement the corresponding action, which is the integration of a multi-discipline field of study.Speech recognition technology has great prospects for development, this article summarizes a comprehensive history of the development in this area, explained the topic of social significance and economic value. First, a comprehensive analysis of issues of language, voice, basic characteristics, analysis of the speech recognition system modeling algorithm theoretical basis, and how to constitute the basic structure of ASR technology systems, and details of the system works.By the theoretical foundation and identify the technical research we can see that voice recognition system is mainly divided into two categories: one is based on research and production of specialized chips for the hardware, the core, constitutes an embedded speech recognition system; and those based on PC, as the the core hardware structure of the larger speech recognition system.According to SPCE061A SCM's unique embedded speech recognition system and the corresponding integrated development environment, this topic based on voice control design of electric trolley, the system is based on a particular person based embedded speech recognition system can also be adapted to non-specific human voice recognition system. Designed a trolley system and the corresponding entities constitute the assembly, testing process and the preparation of the corresponding system software program, the car can be under the control of speech, the freedom to achieve forward, backward, turn, stop, and other state of motion. This system features the voice audio sampling process, our data must pass a very good compression to save space, the application of the loss of a way to quantify the amount of the main uses of discrete hidden Markov models and other algorithms to achieve the corresponding voice template of training, while achieving the corresponding recognize the command. Finally, the detailed description of the function of IDE integrated development environment to develop operational methods, and how to load and debug programsAt present, speech recognition system to sb-core hardware, mainly to PC machine as the core hardware and the speech recognition system to a dedicated hardware chip as the core of the embedded speech recognition system. In this paper, the stdy is based on SCM SPCEO61A people and non-specific embedded speech recognition system.
