Large screen control system and method based on voice recognition module

Abstract

The invention relates to a large screen control system based on a voice recognition module. The large screen control system is characterized by comprising a large screen, a control part electrically connected with the large screen, a system server connected with the control part and a voice collecting module in data connection with the system server, and the control part is used for receiving an instruction sent by the system server and then adjusting playing information of the large screen according to the instruction. The system can acquire voice information in a near mode and a remote mode,the processing module can compare the byte average interval of an effective instruction with a byte average interval of a whole sentence to judge whether the instruction is real or not, and thus theprobability that misoperation is generated is reduced; a learning system can store instruction information of a new user passing verification, when the new user issues the same instruction many times,quick matching can be conducted, then the verification is conducted directly, the verification steps are reduced, and the work efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a large-screen control system and method based on a speech recognition module. Background technique [0002] With the advent of the information age, the rapid development of computer multimedia technology, the widespread application of network technology, the establishment of command and monitoring centers and network management centers, as well as the conduct of temporary meetings and technical lectures, all desire large-screen, multi-color, High-brightness, high-resolution display effects, while traditional CRT monitors are difficult to meet people's requirements in this regard. The large-screen projector technology developed rapidly in recent years has become an effective way to solve the problem of color large-screen display. The scope of application has been further expanded, and the market has become increasingly active due to the growth of demand. So far...

Problems solved by technology

[0004] However, for most large screens at present, the distance between the speech recognition system of the existing system and the controller needs to be limited within a certain range. For example, the controller of the existing large screen generally needs to be in the same room as the large screen, otherwise it will It affects the collection and recognition of voice. For remote controllers who are not in the same room as the big screen or even located in other places, they cannot control the big screen through voice, which is not suitable for the development process of today's global network; and in In actual use, the speech speed, tone, and sentence punctuation of people will change under different circumstances, and the existing electronic equipment will have different degrees of distortion when collecting voice, resulting in inaccurate verification and even subsequent misoperation.
