Aiming at problems such as mobile phone capturing voice information, voice information analysis through semantic platform, and interaction between mobile phone and terminal, the present invention proposes voice control client, semantic analysis platform and DLNA interaction between mobile phone and terminal, and controls customer through voice The terminal receives voice information and sends the voice information to the semantic analysis platform for analysis, comparison, and disambiguation to generate semantic control information, and then the mobile phone sends the semantic control information to the terminal through DLNA to complete the voice control function.

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

FIG. 1 is a flowchart of a voice control method in an embodiment of the present invention. The method includes the following steps:

Step 11, the semantic analysis platform receives the voice information transmitted by the mobile phone terminal.

Wherein, the received voice information is processed through noise reduction and storage of the mobile terminal. In an embodiment of the present invention, the mobile phone terminal can transmit voice information through 3G or WIFI.

Step 12, converting the voice information into text information, and matching the text information with the IPTV data in the semantic database, wherein the semantic database stores the corresponding relationship between text information and control instructions.

Step 13, judge whether there is a matching result, if yes, go to step 14, otherwise go to step 15.

Step 14, the semantic analysis platform sends the control command to the mobile terminal, and the mobile terminal hands the control command to the IPTV set-top box for processing. When the set-top box finally executes the command, it calls the capability of the IPTV platform, but this call is consistent with the non-voice remote control operation of the set-top box.

Step 15, controlling the IPTV to enter a prompt interface, requiring the user to re-input or giving a prompt for possible operation items or prompting the user to operate manually. Among them, the mobile phone client and the set-top box client are responsible for prompting relevant content.

In another embodiment of the present invention, the semantic analysis platform updates the new content of the IPTV platform to the semantic library. For example, there was no program "Where Are We Going, Dad" before, and after "Where Are We Going, Dad" starts broadcasting, we need to update the relevant information of the program to the semantic database. The IPTV platform is installed in the server room of China Telecom. By continuously increasing the content of the speech library, the success rate of matching is increased.

FIG. 2 is a flowchart of a voice control method in another embodiment of the present invention. The method includes the following steps:

Step 21, input voice information through the mobile phone terminal, perform noise reduction and storage processing on the voice information.

The voice information refers to the natural language instruction issued by the user, that is, what the user speaks. Such as "I want to watch Dragon TV", "loud volume" and "I want to watch Zhang Ziyi's movie" and so on.

Noise reduction processing refers to the removal of environmental background noise that may accompany the user inputting voice information.

Storage means that the voice information input by the user is packaged on the mobile terminal and sent to the semantic analysis platform in the form of network packets.

Step 22, transmit the processed speech information to the semantic analysis platform. In this step, voice information can be transmitted through 3G or WIFI. Those skilled in the art should understand that this is only for illustration and should not be construed as a limitation of the present invention, that is, those skilled in the art can also use other methods to transmit voice information.

Step 23, the semantic analysis platform converts the voice information into text information, and matches the text information with the IPTV data in the semantic database, wherein the semantic database stores the corresponding relationship between text information and control instructions.

The semantic analysis platform can be set up in the server room (telecommunication room).

The IPTV data included in the semantic library may involve all relevant information of IPTV content, for example, the name, country, director, actor, show time, and remote control key values corresponding to the increase and decrease of the volume of each movie, etc. The text information identified in the first step of semantic analysis is compared with the content in the semantic database in the second step. For example, if the user says: I want to watch Dragon TV, in the first step, the user's voice information is converted into text information "I want to watch Dragon TV", and in the second step, "I want to watch Dragon TV" is compared with the content in the semantic database After comparison, it is concluded that "I" refers to the user himself, "want to watch" is an operation of playing a video, and "Dragon Satellite TV" is a channel, and the channel number of this channel can be obtained from the semantic database.

In another embodiment of the present invention, the semantic analysis platform can also update the new content of the IPTV platform to the semantic library. For example, there was no program "Where Are We Going, Dad" before, and after "Where Are We Going, Dad" starts broadcasting, we need to update the relevant information of the program to the semantic database. The IPTV platform is installed in the server room of China Telecom. By continuously increasing the content of the speech library, the success rate of matching is increased.

Step 24, judging whether there is a matching result, if yes, go to step 25, otherwise go to step 26.

Step 25, the semantic analysis platform sends the control command to the mobile terminal, and the mobile terminal hands the control command to the IPTV set-top box for processing.

Examples of control instructions are as follows:

Watching Dragon TV means that the IPTV set-top box is switched to the channel of Dragon TV (channel number 101);

Watching Zhang Ziyi's movie refers to playing a movie whose actor's name contains Zhang Ziyi;

A little louder means to increase the playback volume. etc.

Step 26, if the converted text information does not match in the semantic database, the IPTV is controlled to enter a prompt interface, requiring the user to re-input or give a prompt for possible operation items or prompt the user for manual operation.

The present invention proposes a voice control mechanism based on a semantic analysis platform for mobile Internet client applications, that is, the voice information collected by the mobile terminal is analyzed through the semantic analysis platform, and a control command matching the voice information is issued to the mobile terminal, and the The mobile terminal controls the set-top box through DLNA. The invention fully utilizes the mobile phone terminal and the home network, provides a simple operation mode and is easy to implement.
