Human-computer interaction system and method for controlling ip set-top box through smart phone voice

Abstract

The invention discloses a human-computer interaction system and method for controlling an IP set-top box through the voice of a smart phone. The system includes an intelligent terminal and a controlled IP set-top box, and the intelligent terminal and the controlled IP set-top box are connected through a communication network; A collection module, a voice recognition module, a voice command screening module, and a voice control module; the voice recognition module is connected to the voice cloud computing platform through the Internet. The present invention utilizes the smart phone to realize the voice control of the set-top box, the operation is simple and the cost is low; the voice recognition is carried out through the cloud computing platform, and a large amount of accent, vocabulary and other data are collected, and the voice recognition rate is high; the voice command is screened to effectively weaken the accent , dialect, noise, etc., hit the user's desired command, and improve the accuracy of voice control; can realize semantic recognition through the custom voice input function, and can map the user's desired voice to the corresponding operation, further improving voice control accuracy.

Description

technical field [0001] The invention relates to a human-computer interaction system and method for controlling an IP set-top box through voice of a smart phone. Background technique [0002] For many consumers, the buttons of the TV remote control are too complicated, which brings great inconvenience. Therefore, in response to the needs of consumers, with the continuous upgrading and rapid development of TVs, TVs have developed to the point where they can complete various operations such as changing channels and volume adjustments only by voice commands, without the need for a remote control. Simpler and more convenient. [0003] For users of IP set-top boxes, human-computer interaction has always been a problem for users. Traditional remote controls are inconvenient to use and cannot quickly respond to user-expected actions. With the increasing content of IPTV platforms, this problem has become increasingly prominent. At present, in order to meet the market demand, a batc...

AI Technical Summary

Problems solved by technology

[0003] For IP set-top box users, human-computer interaction has always been a problem that plagues users. Traditional remote controls are inconvenient to use and cannot quickly respond to user-expected actions. With the increasing content of IPTV platforms, this problem has become increasingly prominent.

At present, in order to meet the market demand, a batch of professional remote controls based on somatosensory, voice input, QWERTY keyboard and other technologies have also appeared on the market, but the prices are too expensive for ordinary consumers to accept.

[0004] In addition, the existing IP set-top box remote control system based on voice control generally has the following problems: (1) the voice recognition is based on the local voice library, the vocabulary is limited, and the recognition rate is not high; (2) the voice command is not screened, due to the accent , dialect, noise, etc., the accuracy of voice control is low, and the recognition effect is poor; (3) only the voice content can be recognized, but the semantics cannot be intelligently recognized, such as: voice input "mango station" cannot be recognized according to the semantics The "Hunan Satellite TV" that the user wants to express, the degree of intelligent recognition is not high enough, and the recognition effect is not ideal
