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

Abstract

The invention discloses a human-computer interaction system and method controlling an IP set-top box through smart phone voice. The system comprises a smart terminal and the controlled IP set-top box, wherein the smart terminal and the controlled IP set-top box are connected through a communication network, the smart terminal comprises a voice acquiring module, a voice identifying module, a voice instruction screening module and a voice controlling module, and the voice identifying module is connected with a voice cloud computing platform through the Internet. According to the human-computer interaction system and method controlling the IP set-top box through the smart phone voice, voice control over the set-top box is achieved through a smart phone, operation is simple, and cost is low; voice identifying is performed through the cloud computing platform which collects a large amount of data of voice, vocabularies and the like, and the voice identifying rate is high; voice instructions are screened, the effects caused by accents, dialects, noise and the like are effectively weakened, the instruction expected by a user is hit, and accuracy of the voice control is improved; semantic identifying can be achieved through a custom voice input function, the voice expected by the user can be mapped to corresponding operation, and the accuracy of the voice control is further improved.

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...

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
