[Abstract]:With the continuous updating and upgrading of computer performance, personal computers have gradually moved towards miniaturization. Wearable computer is an important representative of microcomputer wearable computing has become a hot spot in the research of various Internet enterprises, each of which has introduced related wearable computing products. Typical of them are Google's smart glasses 尉 Project Glass o, Samsung's smartwatch 尉 Galaxy Gear, which are now on the market. In addition, there are many wearable computing products in some professional fields, especially in the medical and military fields. Sound, as an important medium for the dissemination of information in nature, has brought people a large number of applications of environmental information sound recognition technology in wearable computers, which is in line with the development direction of wearable computers. That is to say, the application of the technology of enhancing human's ability and assisting human's production activity sound recognition enhances human's auditory ability, and when analyzing audio signal, the information of audible object is feedback on wearable computer with network function. Each wearable computer can be used as the node in the network. The collected information can be shared with other nodes through the network center, and the center will integrate and analyze the information in a wide range of environments, so as to add the environment-aware function to the wearable computer. In this paper, a large number of domestic and foreign literatures are reviewed, and the development and present situation of wearable computer and sound recognition field are discussed, and the difference between sound signal and speech signal is analyzed. The technical foundation and framework of developing sound recognition system are determined. By studying the theory of sound recognition, the preprocessing feature extraction of sound signal and the recognition technology based on HMM model are put forward, and according to the characteristics of wearable computer, Combined with the purpose of environment awareness, the frame structure of the whole system and the function of each module are determined, and the design of this system adopts the C graphical user interface application program QT, which is cross-platform, to realize the development of each module function. Finally, the actual use of the system is tested, the performance of the system is analyzed, and the desirable points of the system and the areas that need to be improved are summarized.
