Design And Implementation Of Voice Control System Based On Android

With the continuous improvement of the level of economy, traditional ways of human-computer interaction such as keyboard, touch screen have become increasingly unable to meet the needs of people,Voice control technology is applied more and more widely in people's lives.The traditional voice control system adopts perconal computer voice control or embedded speech chip to control, its existing single occasion,not enough memory, two times the development difficulties,not high recognition and so on.The emergence of mobile and cloud platform solve this problem in a certain extent, especially the rise of Android system makes the voice control system have a more broad development space.Based on Android system,Wifi and 4G technology,an voice control system is developed, which has low cost and multiple control modes, broad application prospect and market value.Aiming at the existing problems of voice control system,This thesis designs a control system based on Android voice.The main work of this thesis includes the following three parts:1) Complete the overall design of the speech control system. These include: the overall design requirement analysis, hardware design, software program.2) Completed the hardware design of voice control. This includes: the design of the control hardware schematic design, Wifi communication circuit, Bluetooth communication circuit voice.3) The use of confidence based algorithm to complete the design of application software based on Android. These include: the design of template design, algorithm design, software interface design, function module design, data communication and recognition interface.After the completion of the design of the voice control system, through a series of tests on the system, and the comparison with other system, this thesis proved that the voice control system has a high practical value.
