[0042] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0043] The main solution of the embodiment of the present application is: obtaining the voice information sent by the slave device, the voice information including the voice command information issued by the user and received by the slave device; performing a text conversion operation on the voice information to form text information; when the text information meets the set control conditions, executing the control operation corresponding to the text information.

[0044] In the prior art, when a user wants to control a display device, he needs to control it by touching the screen, using control keys designed on the display device, or using a remote controller. When the user's hands need to perform other activities, the user cannot control the operation of the display device, which affects the user's normal use of the display device and reduces the user's enjoyment of the display device.

[0045] like Figure 1 As shown, Figure 1 It is a schematic diagram of the terminal structure of the display device involved in the embodiment of the present application.

[0046] like Figure 1 As shown, the terminal may include: a processor 1001, such as a CPU, a network interface 1004, a user interface 1003, a memory 1005, and a communication bus 1002. Among them, the communication bus 1002 is used to realize the connection and communication between these components. The user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the optional user interface 1003 may also include a standard wired interface and a wireless interface. The network interface 1004 may optionally include a standard wired interface and a wireless interface (such as a WI-FI interface). The memory 1005 may be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory. The memory 1005 may also be a storage device independent of the aforementioned processor 1001.

[0047] Optionally, the terminal may also include a camera, an RF (Radio Frequency) circuit, a sensor, a remote controller, an audio circuit, a WiFi module, a detector, etc. Of course, the terminal may also be configured with other sensors such as a gyroscope, a barometer, a hygrometer, a temperature sensor, etc., which will not be described in detail here.

[0048] Those skilled in the art will understand that Figure 1 The terminal structure shown in the figure does not constitute a limitation on the terminal system, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0049] like Figure 1 As shown, the memory 1005 as a computer-readable storage medium may include an operating system, a network communication module, a user interface module, and a control program for a display device.

[0050] exist Figure 1 In the terminal shown, the network interface 1004 is mainly used to connect to the backend server and perform data communication with the backend server; the user interface 1003 is mainly used to connect to the client (user end) and perform data communication with the client; and the processor 1001 can be used to call the control program of the display device stored in the memory 1005 and perform the following operations:

[0051] Acquire the voice information sent by the slave device, wherein the voice information includes voice command information sent by the user and received by the slave device;

[0052] Performing text conversion operation on the voice information to form text information;

[0053] When the text information satisfies the set control condition, a control operation corresponding to the text information is executed.

[0054] An embodiment of the present application also provides a method for controlling a display device.

[0055] Reference Figure 2 , Figure 2 This is an embodiment of the present application. In this embodiment, the control method of the display device includes:

[0056] Step S10, acquiring the voice information sent by the slave device, wherein the voice information includes the voice command information sent by the user and received by the slave device;

[0057] In the voice control method of the display device of the embodiment, the display device (master device) and the slave device are determined from the devices connected to the same local area network according to the network address, wherein the display device includes: smart large-screen TVs and smart large-screen range hoods or smart large-screen refrigerators and other electronic devices with smart large-screen functions, and the slave device includes: mobile phones, laptops, desktop computers and other devices with the ability to collect user voiceprint information. In this embodiment, the control operation is to perform a search and / or play operation on text information.

[0058] The slave device obtains the voice command information sent by the user through the microphone sequence inside the device, performs encoding operation on the voice command information to form voice information and sends it to the display device. There may be multiple master devices that control the operation by sending voice information from the slave device. Specifically, when there are multiple master devices connected to the slave device, the device ID name of the master device with established connection can be read for identification. When the slave device receives the voice command information sent by the user, it sends the voice information to the master device to be controlled by the voice command information. For example, in the ID name recognition table of the slave device, the ID name of the range hood is large-screen range hood, and the determined sending names stored in the mapping with the ID name of the large-screen range hood include: range hood, AA, etc. When the voice command information input by the user is received as "AA plays "Rice Fragrance", the ID name of the master device corresponding to the sending name AA is identified as a large-screen range hood through the ID name recognition table, and the acquired voice command information is encoded to form voice information and sent to the master device large-screen range hood.

[0059] Furthermore, in the present application, the working state of the master device connected to the slave device can also be obtained to determine that the obtained voice command information is encoded into voice information and sent to the corresponding master device. Taking the slave device as an example, the master device (display device) connected to the mobile phone includes: smart TV, large-screen range hood, large-screen refrigerator, large-screen air conditioner and other devices that can receive voice information of the slave device connected to it. When the voice information input by the user is "enter the sports channel to play NBA games", the user does not enter the device name of the master device, but the slave device can determine the master device that receives the voice information based on the working state of the master device connected to it. Specifically, when the mobile phone obtains that only the large-screen range hood is currently started, the voice information of "enter the sports channel to play NBA games" is sent to the large-screen range hood. If multiple master devices are currently in working state, the device that the user recently opened is analyzed as the master device that receives the voice information.

[0060] Step S20, performing a text conversion operation on the voice information to form text information;

[0061] When the display device receives the voice information, it performs a text conversion operation on the received voice information to convert it into text information.

[0062] The step of performing a text conversion operation on the voice information to form text information comprises:

[0063] Step S21, sending the voice information to a voice recognition module;

[0064] Step S22, controlling the speech recognition module to recognize the speech information and complete the conversion operation to form text information; and / or,

[0065] When the display device receives the voice information sent by the slave device, it sends the voice information to the voice recognition module of the master device to convert the voice information sent by the slave device into text information that the master device can transcode. When the device receives the voice, it can convert the voice information into text information through the built-in voice recognition module, which improves the efficiency of voice recognition.

[0066] Step S23, sending the voice information to an online recognition platform, so that the online recognition platform converts the voice information into text information;

[0067] Step S24, receiving text information fed back from the online recognition platform to obtain text information corresponding to the voice information.

[0068] In addition, the display device can also send the acquired voice information to the online recognition platform to convert it into text information. The online recognition platform recognizes the received voice information and converts it into text information. By sending the received voice information to the online platform for recognition, the cloud engine is used, which has a stronger recognition rate and higher robustness.

[0069] Furthermore, the main device can send the voice information to the voice recognition module and the online recognition platform at the same time, and compare the recognition results of the two. When the comparison is consistent, it is determined that the recognition is correct. In this way, the accuracy of the acquired text information is increased. The main device stores the conversion record of the voice recognition module converting the received voice information into text information, and obtains the conversion record within the preset time range to generate a conversion record table. The conversion record is analyzed and counted to form a record of the user's use in the display device, and it is sorted. When receiving the voice information sent by the slave device, the main device sends it to the voice recognition module and the online recognition platform. After the voice recognition module completes the conversion operation, the converted text information is compared with the text information ranked first in the conversion record. If the comparison results are consistent, it is confirmed that the recognized text information is correct. Since users often have a habit of using specific devices, the user's usage habits are used to determine whether the text information recognized by the voice recognition module is correct, and there is no need to wait for the online platform to recognize the text information for feedback, thereby improving the accuracy and efficiency of text recognition.

[0070] Step S30: When the text information satisfies the set control condition, a control operation corresponding to the text information is executed.

[0071] After the main device acquires the text information, it further determines whether the text information satisfies the set control condition. When it is determined that the text information satisfies the set control condition, the control operation corresponding to the text information is executed.

[0072] The control condition is whether the text in the text information is an instruction to control the main device to perform a corresponding control operation. For example, if the text information of the voice command information issued by the user is recognized as "turn on the TV, basketball", because the control operation that the user needs the main device to perform cannot be recognized, it is determined that the text information does not meet the set control condition; if the text information of the converted voice information is recognized as "the TV enters the sports channel to play NBA games", it is determined that the text information meets the set control condition, and the TV is controlled to perform the operation of entering the sports channel to play NBA.

[0073] In this embodiment, the slave device obtains the voice command information issued by the user, encodes the voice command information into voice information and sends it to the master device. The master device receives the voice information of the slave device and converts it into text information, and then determines whether the text information meets the set control conditions. When the text information meets the set control conditions, the control operation corresponding to the text information is executed. The master device can execute the control operation corresponding to the voice information according to the voice information sent by the slave device, thereby improving the convenience of the master device control.

[0074] Reference Figure 3 , Figure 3 In another embodiment of the present application, when the text information satisfies a set control condition, the step of executing a control operation corresponding to the text information includes:

[0075] Step S31, sending the acquired text information to a target database for text matching;

[0076] Step S32: when the text matching is successful, it is determined that the text information meets the set control condition, and a control operation corresponding to the text information is executed.

[0077] The target database stores text information corresponding to the operation instructions. In the present embodiment, the operation instructions are text instructions generated according to the characteristics of the user's voice instruction information. Instructions formed by "execution object + specific operation" such as "open iQiyi to play Joy of Life", "control the volume to reduce 5dB", "open the browser to search for the explanation of the binary tree" are called operation instructions. The acquired text information is matched with the operation instruction, and it is determined whether the acquired text information is text information of the control operation type according to the matching result. If so, the control operation corresponding to the text information is executed. In the present embodiment, when the text information is an operation instruction, the display device can be controlled to execute the control operation corresponding to the text information, so as to realize the control of the display device to execute the control operation corresponding to the text information, thereby improving the intelligence of controlling the display device to execute the control operation.

[0078] The step of matching the acquired text information with the stored operation instructions comprises:

[0079] Step S311, extracting keywords from the text information, and sending the keywords to a target database for text matching.

[0080] In this embodiment, keywords in the text information can be extracted, and the keywords of the operation instructions stored in the database are sent according to the keywords of the extracted text information for matching. For example, when the text information formed after the voice information sent from the device is recognized as "open NetEase Cloud and play Deng Ziqi's "Bubble", the extracted keywords are "NetEase Cloud", "Bubble" and "Deng Ziqi", and the extracted keywords are matched with the keywords of the stored operation instructions. The execution object in the keywords is NetEase Cloud, and the specific operation is to play Deng Ziqi's "Bubble". It is determined that there is an operation instruction corresponding to the acquired text information in the database, and the control operation corresponding to the text information is executed.

[0081] Furthermore, in this embodiment, the names of the various applications downloaded in the main device can be obtained and set as execution objects, and they can be stored one by one in the database. When a specific execution object is matched according to the text information, the application is controlled to be started, thereby improving the speed of controlling the main device through the slave device.

[0082] Step S33, when the text matching fails, obtaining a similar text that is consistent with the pronunciation of the keyword of the text information;

[0083] Step S34: sending the similar text to the target database instead of the keyword for text matching.

[0084] When the text information matching fails, further check whether there is similar text in the text information that is homophonic with the execution object. If so, correct the keywords in the text information and perform the matching operation again. When the matching is successful, execute the control instruction corresponding to the text information.

[0085] In this embodiment, the execution object is extracted from the text information that fails to match to check whether the execution failure is caused by an error in the execution object. If so, the execution object is changed to a correct execution object, thereby improving the success rate of recognition.

[0086] Reference Figure 4 , Figure 4 This is a flow chart of another embodiment of the present application. Before the step of obtaining the voice information sent from the device, it includes:

[0087] Step S01, obtaining a first distance between a user and the display device;

[0088] Step S02, when the first distance is greater than a preset distance, obtaining a second distance between a device associated with the display device and the user;

[0089] Step S03: determine that the device with the smallest second distance value is the slave device.

[0090] The first distance is the distance between the user and the display device. When the first distance between the user and the display device is greater than the preset distance, it is confirmed that the voice command information issued by the user needs to be obtained from the slave device. The distance between the device associated with the display device and the user is further obtained, wherein the distance between other devices associated with the display device and the user is called the second distance. The value of each second distance is obtained, and the device with the smallest value is determined to be the slave device of the display device. When the user inputs voice command information, the slave device is controlled to perform encoding operation on the voice information obtained through the microphone sequence and then send it to the display device. In this embodiment, when there are multiple slave devices associated with the display device, the device closest to the user is determined to be the slave device to accurately obtain the voice command information issued by the user.

[0091] When the text information satisfies the set control condition, after the step of executing the control operation corresponding to the text information, the method includes:

[0092] Step S40, when the control operation of the voice information is identified as a target type of control operation, obtaining the current playback information of the slave device, and determining whether the current playback information of the slave device is consistent with the playback information of the control operation;

[0093] Step S50: when the current playback information of the slave device is consistent with the playback information of the control operation, the initial playback position of the playback information is jumped to the playback position of the slave device.

[0094] The target control operation is an operation for controlling the display device to play music and videos. When the display device executes the control operation corresponding to the text information, it determines whether the control operation is a target control operation, and the target control operation is an operation for controlling the display device to play music and videos. When the display device determines that the control operation corresponding to the text information is a target control operation, it obtains the current playback information from the device. When it is identified that the playback information currently executed by the slave device is consistent with the playback information of the control operation, it obtains the playback position of the content information currently played by the slave device executing the playback function, and controls the display device to jump the starting position of the playback information to the position played by the display device. When the current playback information of the slave device is inconsistent with the playback information of the voice information, the initial playback position of the playback information is set to the starting position of the playback information.

[0095] In this embodiment, by controlling the starting playback position of the display device to play information, the user does not need to manually adjust the starting playback position of the content information when the display device plays the content information from the device, thereby improving the intelligence of the voice-controlled display device.
