Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
In the existing implementation scheme, the process of voice interaction between a user and an electronic device is as follows: a user sends out a voice instruction; correspondingly, the electronic equipment picks up the voice signal through a microphone; the electronic equipment matches the voice signal with a preset name signal, wherein the name signal is the voice signal of the name of the electronic equipment, and the matching step is used for determining whether the voice signal is a voice instruction sent by the electronic equipment; and if the matching result is consistent, matching the voice signal with the voice signal corresponding to each function, and if the matching is successful, executing the corresponding function by the electronic equipment.
However, the electronic device has a high recognition error rate for the voice command of the user, and is prone to have no response or a response error to the voice command sent by the user, thereby reducing user experience.
Therefore, the application provides a device control method and device and an electronic device, which can reduce the voice instruction recognition error rate of the electronic device and improve the user experience.
First, an application scenario of the device control method of the present application is illustrated.
The device control method is applicable to control devices, and the control devices can be used for controlling electronic devices such as mobile phones, tablet personal computers (PADs), smart sound boxes, smart televisions and the like. The control device may be integrated in a certain electronic device controlled by the control device, as a part of the electronic device, and at this time, the electronic device may be connected to other electronic devices controlled by the control device, as shown in fig. 1A, taking the case where the control device is integrated in the electronic device 1, and may control the electronic devices 1 to 4 as an example; alternatively, the control device may be independent of a plurality of electronic devices to be controlled, and in this case, the control device is connected to each of the electronic devices, and as shown in fig. 1B, the control device exists independently, and controls each of the electronic devices 1 and 2. The control equipment executes the equipment control method, responds to the voice command of the user, and controls the electronic equipment connected with the control equipment to execute the corresponding function.
FIG. 2 is a flow chart of one embodiment of a method for controlling a device of the present application, which may be adapted for use in controlling a device; as shown in fig. 2, the method may include:
step 201: acquiring a first voice signal, and converting the first voice signal into a first character sequence; the first voice signal is a voice signal obtained by picking up sound in the environment.
The conversion of the voice signal into the text sequence in this step can be realized by using a related Automatic Speech Recognition (ASR) method, which is not limited in this application.
Step 202: if the first text sequence does not comprise the equipment keyword or comprises at least two equipment keywords, after the first text sequence is determined to comprise one function keyword and the included function keyword only corresponds to one equipment keyword, sending instruction information to the electronic equipment identified by the equipment keyword; the device keyword is used for identifying the electronic device, the function keyword is used for identifying the function of the electronic device, and the instruction information is used for indicating the electronic device to execute the function identified by the function keyword.
In the method, if a first character sequence does not include a device keyword or includes at least two device keywords, after the first character sequence is determined to include a function keyword and the included function keyword only corresponds to one device keyword, instruction information is sent to the electronic device identified by the device keyword, so that under the condition that the device keyword is not determined in the first character sequence, a response to the first character sequence is completed, namely, a response to a voice instruction issued by a user is completed, the voice instruction recognition error rate can be reduced, and the user experience is improved.
The following examples are provided to specifically describe the implementation of the apparatus control method of the present application.
The control device of the embodiment of the application can be preset with the following information: a device keyword of each electronic device, and a function keyword of a function that each electronic device can perform. The electronic device herein is an electronic device that can be controlled by a control device.
And the equipment key words are used for identifying the electronic equipment. The device keywords are different for different electronic devices. For the user, the device keyword can be regarded as the "name" of the electronic device, and when the user issues a voice instruction, the user can indicate the electronic device that the user wants to execute the voice instruction by speaking the name of the electronic device; for the control apparatus, the control apparatus may determine the electronic apparatus that executes the function indicated in the voice signal by judging an apparatus keyword included in the voice signal obtained by sound pickup. For example, if the electronic device is an air conditioner, and the device keyword of the air conditioner is "air conditioner", that is, if the name of the air conditioner is "air conditioner", the user may issue a voice command such as "air conditioner, xxxx", thereby indicating that the user wants to execute the voice command is air conditioner; accordingly, the control apparatus may obtain a corresponding voice signal by picking up the voice instruction, and determine the electronic apparatus to execute the function indicated by the voice signal by recognizing that the apparatus keyword included in the voice signal is "air conditioner".
The device keyword may consist of one or more words. For example, the above-mentioned device keyword "air conditioner" is a word, and if the device keyword is "air conditioner", it may be considered to be composed of two identical words "air conditioner".
Each electronic device may generally perform a variety of functions, for example, an air conditioner may perform temperature up, down, on, off, etc. functions, and a television may perform volume up, volume down, on, off, etc. functions. Corresponding function keywords can be set for the functions of the electronic equipment. The function keyword is used for identifying a function of the electronic device. For the same electronic equipment, the function keywords corresponding to different functions are different, so that the control equipment can distinguish different functions of the same electronic equipment through the function keywords.
For example, keyword information preset in the control device is shown by table 1.
TABLE 1
Preferably, in this embodiment of the application, function keywords corresponding to the same function of different electronic devices are different, and function keywords corresponding to different functions of different electronic devices are different. For example, in table 1, the function keywords corresponding to the opening function of the air-conditioning television are all "open", the function keywords corresponding to the closing function are all "closed", different function keywords can be set for the function keywords, in particular, for the convenience of user memory, and the user experience is improved, the function keywords of the functions in the electronic device can be set according to the characteristics of the electronic device itself, for example, as shown in table 2 below, the function keywords are set as "program start" for the opening function of the television, and the function keywords are set as "program end" for the ending function of the television, so that the characteristics of the television are embodied, and the user can conveniently memorize and issue voice instructions.
TABLE 2
The above keyword information may be preset in the control device when the control device is shipped from the factory.
Optionally, in order to facilitate use of the user and improve user experience, the control device may provide a keyword setting interface for the user, and the user edits the information preset in the control device. If the control equipment does not have a display screen or the display screen cannot display the interface, the keyword setting interface can be displayed on the display screen of electronic equipment connected with the control equipment, such as a mobile phone, and the electronic equipment displaying the keyword setting interface sends the edited content of the user to the control equipment, so that the user edits the preset keyword information in the control equipment. For example, referring to fig. 3, a schematic diagram of a possible implementation of a keyword setting interface is shown in fig. 3, keyword information exemplified in table 1 is shown in fig. 3, and editing controls of each device keyword and function keyword, such as "add," "delete," "modify," and other controls shown in fig. 3, are provided for a user, and the user performs editing operations on the device keyword and the function keyword. After the user finishes editing the device keywords and the function keywords, the control device may update the table 1 according to the editing operation of the user to obtain an updated table 1.
It should be noted that, in the process of using the control device, the user may open the keyword setting interface at any time to edit the keyword information preset in the control device, which is not limited in the present application.
Based on the information preset in the control device, a device control method, such as that shown in fig. 4, may be performed, and as shown in fig. 4, the method may include:
step 401: the control equipment acquires a first voice signal and converts the first voice signal into a first character sequence.
The first voice signal is a voice signal obtained by picking up sound in the environment. The first voice signal may be picked up by a microphone provided in the control apparatus from sounds in the environment.
Step 402: the control device determines whether the first text sequence comprises only one device keyword, if yes, step 403 is performed, if no, step 408 is performed.
For example, if the preset keyword information in the control device is shown in table 1, this step may sequentially determine whether the first text sequence includes the device keyword "air conditioner" of the air conditioner in table 1, and whether the first text sequence includes the device keyword "smart tv" of the tv in table 1. The following three cases are distinguished:
if the first text sequence obtained by conversion in step 401 is "air conditioner, temperature is increased", then it may be determined that the first text sequence only includes an equipment keyword "air conditioner", and step 403 is executed;
if the first character sequence obtained by conversion in step 401 is "air-conditioning and air-conditioning smart television, temperature is increased", then it can be determined that the first character sequence includes two device keywords "air-conditioning and air-conditioning" and "smart television" in this step, and step 408 is executed;
if the first text sequence obtained by conversion in step 401 is "smart air conditioner, temperature is increased", then it may be determined that the first text sequence does not include the device keyword in this step, and step 408 is performed.
Step 403: the control device judges whether the first character sequence includes a function keyword corresponding to the first device keyword, if so, step 404 is executed, and if not, step 405 is executed.
For example, in step 402, the first text sequence is "air conditioner, and temperature is increased", and then the first device keyword is "air conditioner. Taking table 1 as 1, the function keywords corresponding to the first device keyword "air conditioner" include 4 function keywords of "temperature increase", "temperature decrease", "turn on", and turn off ", and in this step, the control device may sequentially determine whether the first text sequence includes" temperature increase ", whether the first text sequence includes" temperature decrease ", whether the first text sequence includes" turn on ", and whether the first text sequence includes" turn off ". There are three cases:
assuming that the first character sequence is 'air-conditioning, temperature rising', the judgment result is that the first character sequence includes a function keyword 'temperature rising' corresponding to a first device keyword 'air-conditioning', and step 404 is executed;
assuming that the first text sequence is "air conditioner, temperature rise and temperature rise", the judgment result is that the first text sequence includes 2 function keywords "temperature rise" and "temperature rise" corresponding to the first device keyword "air conditioner", and step 404 is executed;
assuming that the first text sequence is "air conditioner, temperature is increased", the determination result is that the first text sequence does not include the function keyword corresponding to the first device keyword "air conditioner", and step 405 is executed.
Step 404: the control equipment issues first instruction information to first electronic equipment, wherein the first instruction information is used for indicating the first electronic equipment to execute a first function, the first electronic equipment is electronic equipment corresponding to a first equipment keyword, and the first function is a function corresponding to a function keyword included in a first character sequence; the branch flow is ended.
Wherein, if 2 or more than 2 function keywords are included in step 403, the first function may include 2 or more than 2 functions. For example, in the continuation step 403, it is assumed that the first text sequence is "air conditioner, temperature rise and temperature rise", and the first text sequence includes 2 function keywords "temperature rise" and "temperature rise" corresponding to the first device keyword "air conditioner", then in the first instruction information sent by the control device, the first electronic device may be instructed to execute the temperature rise function 2 times, and if the air-conditioning cooling temperature is 26 degrees, after receiving the first instruction information, the air conditioner may raise the temperature 2 times, and the air-conditioning cooling temperature is adjusted to 28 degrees.
Step 405: the control equipment plays first prompt information, and the first prompt information is used for informing a user to issue a voice instruction aiming at the function required to be executed by the first electronic equipment again; step 406 is performed.
For example, the first prompt message may be: does not detect what function "air conditioner" needs to be performed, what function do you want "air conditioner" to perform? Therefore, the user can issue the voice command again after hearing the first prompt message to indicate the function which needs to be executed by the 'air conditioner', at the moment, the user can issue the voice command without carrying the first equipment keyword 'air conditioner', for example, the user can issue the voice command 'temperature rise' again.
Step 406: and the control equipment acquires a second voice signal, converts the second voice signal into a second character sequence, judges whether the second character sequence comprises a function keyword corresponding to the first equipment keyword, if so, executes step 407, and if not, executes step 405. The second voice signal is a voice signal obtained by picking up sound in the environment.
In the example of the continuation step 405, if the user issues the voice command "temperature increase" again, the second text sequence is "temperature increase", and it may be determined that the second text sequence includes the function keyword "temperature increase" of the first device keyword "air conditioner and air conditioner".
Step 407: the control equipment issues second instruction information to the first electronic equipment, wherein the second instruction information is used for indicating the first electronic equipment to execute a second function, and the second function is a function corresponding to a function keyword included in the second character sequence; the branch flow is ended.
Continuing with the example in step 406, the second instruction information is used to instruct the air conditioner to perform the "temperature up 1 degree" function. Accordingly, if the current cooling temperature of the air conditioner is 26 degrees, the air conditioner may increase the cooling temperature to 27 degrees after receiving the second instruction message.
Step 408: and the control equipment judges whether the first character sequence comprises a function keyword corresponding to any equipment keyword, if so, the step 409 is executed, and if not, the branching process is ended.
For example, assuming that the first text sequence is "air conditioner, temperature rise", the determination result is that the first text sequence includes the function keyword "temperature rise" corresponding to the device keyword "air conditioner, and step 409 is executed;
if the first character sequence is 'air conditioner, temperature is increased', the judgment result can be obtained that the first character sequence does not include any function keyword corresponding to any equipment keyword, and the branching process is finished;
if the first character sequence is 'air conditioner, temperature is raised and opened', the judgment result can be obtained that the first character sequence comprises the function keywords 'temperature is raised' and 'opened', and the branching process is finished.
Step 409: the control device determines whether the first function keyword included in the first text sequence corresponds to an apparatus keyword, if so, performs step 410, and if not, performs step 411.
The first function keyword is a function keyword included in the first text sequence.
For example, assuming that the first text sequence is "air conditioner, temperature rise", the first function keyword "temperature rise" can be obtained, and still taking table 1 as an example, it corresponds to only one device keyword "air conditioner, execute step 410;
assuming that the first text sequence is "air conditioner, open", the first function keyword "open" can be obtained, and still taking table 1 as an example, it corresponds to two device keywords "air conditioner, air conditioner" and "smart tv", and step 411 is executed.
Step 410: the control equipment sends third instruction information to second electronic equipment, wherein the third instruction information is used for indicating the second electronic equipment to execute a third function, the second electronic equipment is identified by the equipment keyword corresponding to the first function keyword, and the third function is a function corresponding to the first function keyword; the branch flow is ended.
Step 411: the control device plays the second prompt message, which is used to inform the user to issue the voice command for instructing the electronic device to execute the third function again, and step 412 is executed.
For example, in the continuation step 409, the first function keyword "on" corresponds to two device keywords "air conditioner and" smart tv ", and the second prompt message may be: what electronic device of "air conditioner" and "smart tv" you want to turn on? Therefore, the user can issue the voice command again after hearing the second prompt message to indicate which electronic device needs to execute the 'opening' function, at the moment, the user can issue the voice command without carrying the function keyword 'opening', for example, the user can issue the voice command 'air conditioner' again.
Step 412: and the control device acquires a third voice signal, converts the third voice signal into a third text sequence, judges whether the third text sequence comprises an equipment keyword, and the equipment keyword is an equipment keyword corresponding to the first function keyword, if so, executes the step 413, otherwise, returns to execute the step 411.
The third voice signal is a voice signal obtained by picking up sound in the environment.
Continuing the example in step 411, if the user issues the voice instruction "air conditioner and air conditioner" again, the third text sequence is "air conditioner and air conditioner", it may be determined that the third text sequence includes the device keyword "air conditioner and air conditioner", and step 413 is executed;
if the user issues the voice command "air conditioner" again and the third text sequence is "air conditioner", it may be determined that the third text sequence does not include the device keyword, and step 411 is executed.
Step 413: and the control equipment sends fourth instruction information to third electronic equipment, the third electronic equipment is the electronic equipment of the equipment keyword identifier included in the third character sequence, and the fourth instruction information is used for indicating the third electronic equipment to execute a third function.
For example, in the continuation step 412, assuming that the first function keyword is "on", and the user issues the voice command "air conditioner and air conditioner again", the third electronic device is an air conditioner, and the fourth command information is used to instruct the air conditioner to perform the "on" function.
In the method shown in fig. 4, if the first text sequence does not include only one device keyword, it is still continuously determined whether the first text sequence includes one function keyword corresponding to any device keyword, and when the function keyword included in the first text sequence corresponds to only one device keyword, third instruction information is sent to the second electronic device, so that under the condition that the device keyword is not specified in the first text sequence, the response to the first text sequence is completed, that is, the response to the voice instruction issued by the user is completed, thereby reducing the voice instruction recognition error rate of the electronic device and improving the user experience. Especially, if the same or different functions of different electronic devices correspond to different function keywords, for example, as shown in table 2, the function keywords included in the first text sequence necessarily correspond to only one device keyword, so that even if the device keywords in the first text sequence are ambiguous, it is still ensured that the response to the first text sequence, that is, the response to the voice command issued by the user, is completed, thereby further reducing the voice command recognition error rate of the electronic device and improving the user experience.
