| With the development of the speech recognition technology and embedded technology, the speech recognition is chose to be one of the control methods of equipment. Many lager companies and research institutions have designed a huge number of voice recognition chips with superior performance and high reliability. These chips are used in consumer electronics, for example, household appliances, intelligent toys, mobile phones, game consoles, etc. In the future, the speech recognition technology must be widely used in the field of the Internet of things. Predictable, speech recognition technology will be more extensive in the application of modern electronics.In this paper, I finished the design of the intelligent globe based on speech recognition technology. This paper includes the following aspects:First, after doing research and analysis about the history and the present situation of the speech recognition technology, a new system design of the speech recognition was definite which could achieve the recognition of non-specific speech.Second, I designed the speech recognition part. The function of this part is doing the recognition of speech. In the experimental test, the accuracy of this system is satisfactory. And the globe-control part was designed. In this part, the microcontroller is the most important component. The turn of the globe is controlled by the MCU.At last, these modules are connected to be a whole thing. Then I did some debugging to make sure this system work well. After completing the system, some possible solutions of improving the system performance were proposed. And I gave some suggest of extending the system function.The result of the experiment showed that the intelligent globe based on speech recognition technology achieved the function of recognition of the non-specific human speech and controlling the globe to turn to the target position. In this design, most chip and devices chose are those that have been proved to be mature and reliable. The design is stable and efficient. More research could be done in upgrading and improving this system, includes:expansion of the identified entries, reducing the affection of the background noise, improving stability, expansion the system functions. |
