Here, the embodiment of the present invention is not particularly limited.
Further, in combination with the system for waking up the application service, an embodiment of the present invention provides a method for waking up the application service, where the method for waking up the application service is applied to a virtual personal assistant.
Fig. 2 is a first flowchart illustrating a method for waking up an application service according to an embodiment of the present invention, and referring to fig. 2, the method for waking up an application service may include:
s201: receiving first voice information input by a user through an earphone when the virtual personal assistant is in an awakening state;
specifically, in order to reduce the power consumption of the electronic device, when the user needs to use the application service of the virtual personal assistant, the virtual personal assistant is in an awake state, such as an operating mode, a non-power saving mode, and the like, and at this time, when the virtual personal assistant receives the first voice information input by the user through the headset, the virtual personal assistant can determine the service requirement information of the user based on the voice information input by the user, so as to provide the corresponding application service to the user. When the user does not use the virtual personal assistant for a long time or the earphone is disconnected with the electronic device installed with the virtual personal assistant, the virtual personal assistant can be in an un-awakened state, such as standby, sleep, power saving mode and the like. When the virtual personal assistant is in an un-awakened state, the virtual personal assistant can receive voice information input by a user and can determine whether preset awakening words exist in the voice information, but the virtual personal assistant cannot perform semantic recognition on the voice information input by the user, cannot determine service requirement information of the user, and cannot provide application services for the user.
S202: determining service demand information of a user based on the first voice information;
specifically, when the virtual personal assistant is in an awake state, and the virtual personal assistant receives first voice information input by a user through an earphone, the virtual personal assistant determines service requirement information of the user according to the first voice information, so that local application services in the virtual personal assistant are awakened according to the service requirement information, and application services are conveniently provided for the user.
The following describes how to determine the service requirement information of the user based on the first voice information input by the user by using a specific example.
Illustratively, taking the calculation-type application service as an example to illustrate how to determine the service demand information of the user, when the first voice information input by the user is "how much the calculation 125 multiplied by 0.85 is equal to" and how much money is left after eight-fold for the help me calculation 125 yuan ", it can be determined that the service demand information of the user is" open the calculation-type application service, and the calculation 125 multiplied by 0.85 "; when the first voice information input by the user is ' open a calculator ', ' i want to perform exchange rate calculation ', ' i want to calculate a money sum in the month ' and the like ', it can be determined that the service requirement information of the user is ' open a calculation type application service '.
Exemplarily, the music application service is taken as an example to explain how to determine the service requirement information of the user, and when the first voice information input by the user is "i want to listen to song of zhang san", the service requirement information of the user may be determined as "open the music application service, play music of zhang san"; when the first voice information input by the user is 'play music', 'play song', 'sing me for a song', 'i want to listen to a song' and the like, it can be determined that the service requirement information of the user is 'open music application service, play default music'; when the first voice information input by the user is 'play the caucasian balloon', the service requirement information of the user can be determined to be 'open music application service and play music with the name of the song of the caucasian balloon'.
S203: and awakening the local application service capable of meeting the service requirement information in the virtual personal assistant.
The local application service is provided by the virtual personal assistant, and the application service can be realized without connecting an electronic device where the virtual personal assistant is located with a network. In practice, the virtual personal assistant is a separate application program that can be installed in the electronic device, and the local application service is only the application service in the virtual personal assistant, not a separate application program.
In the specific implementation process, in order to avoid the situation that the user installs too many third-party application programs, the burden of the user is reduced, the user experience is improved, and the virtual personal assistant can provide various convenient local application services for the user. Then, after determining the service requirement information of the user, the virtual personal assistant can wake up the local application service capable of meeting the service requirement information in the virtual personal assistant.
In practical applications, the above-described local application service may be implemented by various types of application services. Specifically, the network application service described in the embodiment of the present invention may be a computing application service, such as a scientific calculator, an exchange rate calculator, a personal income tax calculator, a discount calculator, or the like, a timing reminding application service, such as an alarm clock, a schedule, or the like, a recording application service, such as a notepad, a note, or the like, or, of course, another type of service, such as an audio playing application service, a dictionary application service, or the like. Here, the embodiments of the present invention are not particularly limited.
In practical applications, the application services in the virtual personal assistant include network application services and local application services. Wherein the number of the application services in the virtual personal assistant is one or more.
As can be seen from the above, in the method for waking up an application service provided in the embodiment of the present invention, when the virtual personal assistant is in the wake state, after the virtual personal assistant receives the first voice information input by the user through the headset, the virtual personal assistant may determine the service requirement information of the user based on the first voice information, and then wake up a local application service capable of meeting the service requirement information in the virtual personal assistant by the virtual personal assistant, so as to provide the application service to the user, where the local application service is provided by the virtual personal assistant. Therefore, the user does not need to manually operate the electronic equipment, the user only needs to input voice information through the earphone, the local application service in the virtual personal assistant can be awakened through the virtual personal assistant, the operation is very simple and convenient, the operation process of awakening the application service is simplified, and the intelligent degree of an interaction mode is improved.
Based on the foregoing embodiments, in other embodiments of the present invention, in order to obtain the service requirement information of the user, so that the virtual personal assistant wakes up the matched local application service according to the service requirement information, the above S202 may be implemented by using, but is not limited to, the following method.
The first implementation method intelligently determines the service requirement information of the user through a Natural Language Understanding (NLU) technology.
In a specific implementation process, in order to intelligently and more accurately determine the service requirement information of the user, the step S202 may include: performing voice recognition on the first voice information to obtain text recognition information; and performing semantic understanding on the text recognition information through a natural language understanding technology to obtain service requirement information.
Specifically, when the virtual personal assistant is in an awake state, after the virtual personal assistant obtains the first voice information input by the user, the virtual personal assistant may first obtain text recognition information corresponding to the first voice information through a voice recognition technology, and then analyze and understand the text recognition information through a natural language understanding technology, determine user intention information corresponding to the input voice information of the user, and determine the user intention information as service requirement information.
For example, when the text recognition information corresponding to the first voice information input by the user is "how much the calculation 1052 is multiplied by 50" is, it may be determined that the service requirement information of the user is "open the calculation type application service, and the calculation 1052 is multiplied by 50"; when the first voice information input by the user is ' open a calculator ', ' i want to perform exchange rate calculation ', ' i want to calculate a money sum in the month ' and the like ', it can be determined that the service requirement information of the user is ' open a calculation type application service '.
Exemplarily, when the text identification information corresponding to the first voice information input by the user is "i want to listen to a song of zhang san", it may be determined that the service requirement information of the user is "open a music application service, play music of zhang san"; when the text identification information corresponding to the first voice information input by the user is 'play music', 'play song', 'sing me for a song', 'i want to listen to a song', and the like, it can be determined that the service requirement information of the user is 'open music application service, play default music'; when the text identification information corresponding to the first voice information input by the user is 'play the balloon', it can be determined that the service requirement information of the user is 'open music application service and play the song with the music name of the balloon'.
The second implementation method is to quickly determine the service requirement information of the user through a preset awakening word.
In a specific implementation process, in order to quickly and conveniently determine the service requirement information of the user, the step S202 may include: analyzing the first voice message, and determining whether the first voice message contains a preset awakening word; and if the first voice message is determined to contain the preset awakening word, determining the preset awakening word as the service requirement information of the user.
Specifically, when the virtual personal assistant is in an awake state, after the virtual personal assistant obtains the second voice information input by the user, the virtual personal assistant may detect whether the second voice information includes voice information corresponding to a preset awake word, and if the second voice information includes the preset awake word, determine that the second voice information includes the preset awake word, and determine that the preset awake word is the service requirement information of the user. Or, when the virtual personal assistant is in the wake-up Processing state, after the virtual personal assistant obtains the second voice information input by the user, the virtual personal assistant may also obtain the text recognition information corresponding to the first voice information through a voice recognition technology, then perform word segmentation on the text recognition information through a Natural Language Processing (NLP) technology, extract a keyword in the input voice information of the user, and finally, the virtual personal assistant may compare the preset wake-up word with the extracted keyword, if there is a keyword matching the preset wake-up word, determine that the first voice information includes the preset wake-up word, and determine the preset wake-up word as the service requirement information of the user.
Of course, in addition to the above two implementation methods, other implementation methods may be adopted to determine the service requirement information of the user based on the first voice information. Here, the embodiments of the present invention are not particularly limited.
In another embodiment of the present invention, the above S203 can be implemented by, but not limited to, the following method. In a specific implementation process, in order to wake up a local application service required by a user from all local application services provided by the virtual personal assistant, S203 may include: and awakening the local application service corresponding to the service identification information matched with the service demand information in the virtual personal assistant, wherein the service identification information is service name information or service category information.
Here, the service identification information of the local application service refers to information capable of identifying the local application service. Illustratively, the service identification information may be service name information specific to the local application service, such as a notepad, an exchange rate calculator, a note, an alarm clock, a music player, and the like, and the service identification information may also be service category information to which the local application service belongs, such as music, a dictionary, a timing reminder, and the like.
In addition, in order to ensure that the required application service can be provided to the user, when the virtual personal assistant provides the local application service and the network application service at the same time, the above S203 may further include: matching the preset awakening words with application identification information of local application service in the virtual personal assistant; if the service identification information is matched with the service requirement information, the local application service corresponding to the service identification information matched with the service requirement information in the virtual personal assistant is awakened; and if not, awakening the network application service corresponding to the service identification information matched with the service requirement information in the virtual personal assistant.
Here, the web application service is also an application service in the virtual personal assistant, and is provided by a server with which the virtual personal assistant is associated. In practical applications, the server associated with the virtual personal assistant may be a server provided by a provider of the virtual personal assistant, or may be a server provided by a third party application provider, such as himalaya, dragonfly FM, and the like, and the embodiment of the present invention is not limited specifically herein.
In practical applications, in order to avoid too many third-party application programs installed by a user, reduce user burden and improve user experience, the virtual personal assistant can be associated with a server provided by a third-party application program provider through an API interface provided by the third-party application program for interfacing with the virtual personal assistant, so that the virtual personal assistant can acquire data resources of the web application service required by the user from the server provided by the third-party application program provider, and thus the virtual personal assistant can provide the application service of the third-party application program to the user, and at this time, the web application service is the application service of the third-party application program.
As can be seen from the above, in the method for waking up an application service provided in the embodiment of the present invention, the virtual personal assistant can determine the service requirement information of the user intelligently and accurately through the natural language understanding technology, or can determine the service requirement information of the user quickly and conveniently through the preset wake-up word, and then the virtual personal assistant wakes up the local application service corresponding to the service identification information matched with the service requirement information in the virtual personal assistant. Therefore, the user does not need to manually operate the electronic equipment, the user only needs to input voice information through the earphone, the local application service in the virtual personal assistant can be intelligently awakened through the virtual personal assistant, the operation is very simple and convenient, and the user experience is improved.
Based on the foregoing embodiment, in another embodiment of the present invention, after the virtual personal assistant wakes up the local application service that satisfies the service requirement information of the user, in order to facilitate the user to perform relevant operations on the local application service, it is necessary to output an alert tone to prompt the user that the local application service has been woken up. Then, after the step S203, the method for waking up the application service may further include the steps of: inputting service identification information of the local application service into a preset prompt template as a prompt keyword to generate text prompt information containing the service identification information of the local application service; performing voice synthesis processing on the Text prompt information through a Text To Speech (TTS) technology To generate voice prompt data, wherein the voice prompt data is used for prompting a user that the local application service is awakened; and outputting the voice prompt data to the earphone.
In practical applications, the service identification information may be specific service name information of the local application service, such as a notepad, exchange rate calculation, a music player, and the like, and the service identification information may also be service category information to which the local application service belongs, such as music, a dictionary, a timing reminder, and the like.
For example, taking a preset prompting template as "hello + prompting keyword + application service is awakened", and the service identification information of the local application service is "notepad", for example, the service identification information of the local application service is input into the preset prompting template as the prompting keyword, and the text prompting information including the service identification information of the local application service is generated, so that the "hello notepad application service is awakened".
Of course, in practical applications, in addition to using the above method to notify the user that the local application service has been awakened, other methods may be used to implement the method, such as the virtual personal assistant outputting a preset prompt tone directly to the headset. Illustratively, short prompt tones such as "drip", "beep", "click" and the like are stored in advance in the electronic device system prompt sound library, and a preset prompt sound can be selected for the network application service from the system prompt sound library of the electronic device by a person skilled in the art in an interactive interface of the virtual personal assistant displayed in the electronic device, so that after the network application service is awakened, the virtual personal assistant can directly output the target prompt sound to the earphone and control the earphone to play the target prompt sound to the user. Thus, the user can know that the web application service has been woken up.
As can be seen from the above, in the method provided in the embodiment of the present invention, after the virtual personal assistant wakes up the local application service that can satisfy the user requirement information of the user, the virtual personal assistant outputs the voice prompt data to the earphone, and controls the earphone to play the voice prompt data to the user, so that the user knows that the voice operation can be performed on the application service. Therefore, invalid voice operation of the user can be avoided, the intelligent degree of an interaction mode is improved, and user experience is improved.
Based on the foregoing embodiment, in another embodiment of the present invention, when the woken-up local application service is a computing service such as a scientific calculator, exchange rate calculation, personal accumulation calculation, etc., if a mathematical expression is not explicitly indicated in the input first voice information, the user is further required to input second voice information, and in order to better provide the computing service to the user, the virtual personal assistant is further required to output the voice calculation result to the headset. Then, after the above S203, referring to fig. 3, the above method for waking up the application service may further include the following S301 to S305:
s301: when the local application service is a computing service, receiving second voice information input by a user through an earphone;
here, the second voice information is a mathematical expression indicating to be calculated.
Specifically, when the user needs to use the computing service in the virtual personal assistant, if the mathematical expression is not explicitly indicated in the input first voice message, for example, the first voice message is "open calculator", and the user needs to input the second voice message through the headset, the virtual personal assistant receives the second voice message input by the user, for example, the second voice message is "calculate 125 yuan and make eight folds.
Of course, in practical applications, if the user has explicitly indicated the mathematical expression directly in the first voice message, for example, the first voice message is "calculate 125 yuan what is a lot of money for eighting", then after S203, without performing S301 and S302, the virtual personal assistant may directly extract the mathematical expression from the service requirement information of the corresponding user in the first voice message, and then perform S303 to S305.
S302: performing voice recognition on the second voice information, and extracting a mathematical expression from the second voice information;
specifically, after the virtual personal assistant receives the second voice information input by the user through the earphone, the virtual personal assistant may perform voice recognition on the second voice information to obtain the text recognition information corresponding to the second voice information, and then extract the required mathematical expression from the text recognition information corresponding to the second voice information. In this way, the virtual personal assistant enables intelligent extraction of mathematical expressions from voice information without requiring manual input by the user.
S303: inputting the mathematical expression to a calculation service to obtain a text calculation result;
s304: converting the text calculation result into a voice calculation result by a text-to-voice technology;
