Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a voice assistant wake-up method according to an embodiment of the present invention, which is applied to a mobile terminal, where the mobile terminal is installed with an application having a voice assistant function, and as shown in fig. 1, the method includes the following steps:
In this embodiment, the mobile terminal is configured with a system voice assistant, and is also installed with an application program having a voice assistant function, for example: a voice assistant type application program is installed, or an application program with voice assistant function is installed.
In this step, in a case that the mobile terminal runs the application program, a first wake-up voice signal may be received, specifically, the first voice wake-up signal may be collected by a microphone of the mobile terminal when a user inputs the first voice wake-up signal, where the application program acquires an authority to allow using the microphone, and the first voice wake-up signal may be a voice signal including a specific wake-up word input by the user, for example: including the voice signal of the wake-up word "hello, small a".
It should be noted that, if the application is configured with the permission to allow the background microphone to be called, the first voice wake-up signal may also be received in the case of running the application in the background.
And 102, awakening the system voice assistant under the condition that the first voice awakening signal is matched with a preset awakening word of the system voice assistant.
103, under the condition that the first voice wake-up signal is matched with a preset wake-up word of the voice assistant of the application program, waking up the voice assistant of the application program.
In this embodiment, after receiving the first voice wake-up signal, it may be detected whether the first voice wake-up signal matches a preset wake-up word of the system voice assistant or matches a preset wake-up word of the voice assistant of the application program, where the preset wake-up word of the system voice assistant may be a wake-up word preset by the system voice assistant and used for waking up the system voice assistant, and the preset wake-up word of the voice assistant of the application program may be a wake-up word preset by the application program or customized by a user and used for waking up the voice assistant of the application program. Specifically, the voice of the first voice wake-up signal may be analyzed to determine a wake-up word included in the first voice wake-up signal, and then whether the wake-up word included in the first voice wake-up signal matches a preset wake-up word of the system voice assistant and whether the wake-up word included in the first voice wake-up signal matches a preset wake-up word of the voice assistant of the application program may be detected, or whether the wake-up word included in the first voice wake-up signal matches a preset wake-up word of the system voice assistant may be detected, if so, the detection is not required to be continued, and if not, whether the wake-up word included in the first voice wake-up signal matches a preset wake-up word of the voice assistant of the application program may be detected.
Therefore, if the first voice wake-up signal is detected to be matched with the preset wake-up word of the system voice assistant, the system voice assistant is woken up, namely the system voice assistant foreground is displayed on the current interface, and voice interaction is carried out with a user through the system voice assistant. If the first voice wake-up signal is detected to be matched with a preset wake-up word of the voice assistant of the application program, the voice assistant of the application program is woken up, namely, the voice assistant function of the application program is started, and voice interaction is carried out with a user through the voice assistant of the application program.
For example: referring to fig. 2 and fig. 3, the preset wake-up word of the system voice assistant is "hello, widget a", and the preset wake-up word of the voice assistant of the application B is "hello, widget B", and when the mobile terminal runs the application B, if the voice wake-up signal of "hello, widget a" input by the user is received, the system voice assistant is woken up, and if the voice wake-up signal of "hello, widget B" input by the user is received, the voice assistant of the application B is woken up.
It should be noted that the system voice assistant and the voice assistant of the application may share a recording and voice detection path, or may use independent recording and voice detection paths, respectively, that is, the mobile terminal may receive the first voice wake-up signal only through one microphone, and detect and match the first voice wake-up signal through one voice detection module, or receive the first voice wake-up signal through different microphones, and detect and match the first voice wake-up signal through different voice detection modules.
When the system voice assistant and the voice assistant of the application program share a recording and voice detection path, a preset wake-up word of the system voice assistant and a preset wake-up word of the voice assistant of the application program are required to be trained in a local database of the mobile terminal in advance, so that the mobile terminal can correspondingly wake up the system voice assistant or the voice assistant of the application program according to different voice wake-up signals input by a user.
When the system voice assistant and the voice assistant of the application program use independent recording and voice detection paths respectively, the local database of the mobile terminal does not need to be pre-trained with the preset awakening words of the voice assistant of the application program, and the system voice assistant and the voice assistant of the application program can respectively detect whether the received first voice awakening signal is matched with the corresponding preset awakening words through the respective voice detection paths.
In this way, in this embodiment, the mobile terminal may not only wake up the voice assistant of the application program but also wake up the system voice assistant when running the application program, so that a user only needs to memorize the preset wake-up word of the system voice assistant, and when the mobile terminal runs any application program with the voice assistant, the user can wake up the system voice assistant by the preset wake-up word of the system voice assistant, so that the operation of waking up the voice assistant is simple and convenient, and the user can select between the voice assistant of the application program and the system voice assistant, thereby improving user experience.
In this embodiment of the present invention, the mobile terminal may be any device having a storage medium, for example: terminal devices such as computers (Computer), Mobile phones, Tablet Personal computers (Tablet Personal Computer), laptop computers (laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), and Wearable devices (Wearable Device).
In the voice assistant wake-up method in this embodiment, the mobile terminal may receive the first voice wake-up signal when running the application program with the voice assistant function, and wake up the corresponding voice assistant according to the wake-up word matched with the first voice wake-up signal, so that the user may select between the voice assistant of the application program and the system voice assistant, and further the user may select the system voice assistant without memorizing a large number of wake-up words when running any application program with the voice assistant function, which is simple and convenient to operate.
Referring to fig. 4, fig. 4 is a flowchart of another voice assistant wake-up method according to an embodiment of the present invention, which is applied to a mobile terminal including a first microphone, a second microphone, a first voice detection module, and a second voice detection module. In this embodiment, on the basis of the embodiment shown in fig. 1, the step of receiving the first voice wake-up signal is refined, and the step of detecting whether the first voice wake-up signal received by the first microphone is matched with the preset wake-up word of the system voice assistant by the first voice detection module and the step of detecting whether the first voice wake-up signal received by the second microphone is matched with the preset wake-up word of the voice assistant of the application program by the second voice detection module are added, so that the mobile terminal has higher efficiency and is easier to implement when matching the wake-up word. As shown in fig. 4, the method comprises the steps of:
In this embodiment, the mobile terminal includes a first microphone, a second microphone, a first voice detection module, and a second voice detection module, that is, the mobile terminal includes two recording paths and a voice detection path, so that the mobile terminal can receive the first voice wake-up signal through the first microphone and the second microphone respectively when the mobile terminal runs the application program. Wherein the first microphone may be associated with the system voice assistant, the second microphone may be associated with the voice assistant of the application, the first voice detection module is connected with the first microphone, the second voice detection module is connected with the second microphone, namely, the first microphone sends the collected first voice wake-up signal to the first voice detection module for detection, the first voice detection module detects whether the first voice wake-up signal matches a preset wake-up word of the system voice assistant, the second microphone sends the collected first voice wake-up signal to the second voice detection module for detection, the second voice detection module detects whether the first voice wake-up signal is matched with a preset wake-up word of a voice assistant of the application program.
Optionally, when the mobile terminal is in the power-on state, the first microphone is in the power-on state and the system voice assistant is in the background running state.
In this embodiment, when the mobile terminal is in the power-on state, the first microphone may be always in the power-on state, and the system voice assistant is in the background running state, so that the first microphone may monitor the voice wake-up signal input by the user, perform voice detection and matching, and run the system voice assistant in the foreground if it is detected that the voice wake-up signal input by the user matches a preset wake-up word of the system voice assistant, thereby facilitating the user to wake up the system voice assistant at any time when starting the application program with the voice assistant function. And preferably, the first microphone may adopt a microphone whose power consumption does not exceed a preset power threshold, so as to ensure that the power consumption of the first microphone is low, thereby reducing the power consumption of the mobile terminal.
In this embodiment, the first voice detection module may be a Digital Signal Processing (DSP) chip, and since the power consumption of the first microphone is low and the decibel of the received voice wake-up signal is also correspondingly low, the DSP chip with low power consumption may be used to perform voice detection and matching on the first voice wake-up signal received by the first microphone. Specifically, the first voice wake-up signal received by the first microphone may be first analog-to-digital converted, that is, the first voice wake-up signal is converted from an analog audio signal to a digital signal, the converted digital signal is analyzed to obtain a wake-up word included in the first voice wake-up signal, and finally, the wake-up word included in the first voice wake-up signal is matched with a preset wake-up word of the system voice assistant to determine whether the first voice wake-up signal received by the first microphone is matched with the preset wake-up word of the system voice assistant.
It should be noted that in this embodiment, under the condition that the first voice wake-up signal received by the first microphone is matched with a preset wake-up word of the system voice assistant, as shown in fig. 5, the voice interaction signal subsequently input by the user may be recognized and processed through a voice recognition path corresponding to the system voice assistant, that is, the voice interaction signal subsequently input by the user is recognized and processed through Hardware Abstraction Layer Audio equipment (HAL Audio Device for short), a voice recognizer (soundscript) and a recognition engine corresponding to the system voice assistant.
In this embodiment, the second voice detection module may include a Coder-DECoder (Codec) and an Advanced Digital Signal Processor (ADSP), and the second microphone may be a recording microphone common to the mobile terminal, and since the decibel of the voice wake-up Signal received by the second microphone is higher, and the amount of data to be processed by the second voice detection module is larger, the audio Codec may be used to perform analog-to-Digital conversion on the first voice wake-up Signal received by the second microphone, so as to save resources of the ADSP and improve the operating efficiency of the system.
The ADSP may analyze the converted digital signal to obtain a wakeup word included in the first voice wakeup signal, and finally match the wakeup word included in the first voice wakeup signal with a preset wakeup word of a voice assistant of the application program, so as to determine whether the first voice wakeup signal received by the second microphone matches the preset wakeup word of the voice assistant of the application program.
It should be noted that in this embodiment, in the case that the first voice wake-up signal received by the second microphone is matched with the preset wake-up word of the voice assistant of the application program, as shown in fig. 5, the voice interaction signal subsequently input by the user may be recognized and processed through the voice recognition path corresponding to the voice assistant of the application program, that is, the voice interaction signal subsequently input by the user is recognized and processed through the HAL Audio Device, the Audio recorder (Audio record) and the recognition engine corresponding to the application program.
It should be further noted that, in this embodiment, step 402 and step 403 may be executed in parallel, and there is no time difference between the execution timings.
And step 404, awakening the system voice assistant under the condition that the first voice awakening signal is matched with a preset awakening word of the system voice assistant.
The specific implementation of this step can refer to the implementation of step 102 in the method embodiment shown in fig. 1, and the same beneficial effects can be achieved, and for avoiding repetition, details are not described here.
Step 405, waking up the voice assistant of the application program under the condition that the first voice wake-up signal is matched with a preset wake-up word of the voice assistant of the application program.
The specific implementation of this step can refer to the implementation of step 103 in the method embodiment shown in fig. 1, and the same beneficial effects can be achieved, and for avoiding repetition, details are not described here.
Optionally, after step 405, the method further includes:
and if a second voice awakening signal is received and the second voice awakening signal is matched with a preset awakening word of the system voice assistant, awakening the system voice assistant and closing the voice assistant of the application program.
In this embodiment, after waking up the voice assistant of the application program, if the user experiences the voice assistant of the application program poorly, a second voice wake-up signal matched with a preset wake-up word of the system voice assistant may be input to switch to the system voice assistant for voice interaction.
Therefore, in this embodiment, if a second voice wake-up signal is received and it is detected that the second voice wake-up signal matches a preset wake-up word of the system voice assistant, the assistant of the application program may be turned off and the system voice assistant may be displayed in the foreground, so that the user may perform voice interaction with the user through the system voice assistant.
Similarly, after waking up the system voice assistant, if the user experiences poor interaction with the system voice assistant, a second voice wake-up signal matched with a preset wake-up word of the voice assistant of the application program may be input to switch to the voice assistant of the application program for voice interaction.
Therefore, the user can switch the expected voice assistant to perform voice interaction at any time according to the self requirement in the process of using the voice assistant, so that the mobile terminal has more flexibility.
Of course, the same can be applied to the embodiment shown in fig. 1 and the same advantageous effects can be achieved.
In this embodiment, on the basis of the embodiment shown in fig. 1, the step of receiving the first voice wake-up signal is refined, and the step of detecting whether the first voice wake-up signal received by the first microphone matches with the preset wake-up word of the system voice assistant through the first voice detection module and the step of detecting whether the first voice wake-up signal received by the second microphone matches with the preset wake-up word of the voice assistant of the application program through the second voice detection module are added, so that the mobile terminal has higher efficiency and is easier to implement when matching the wake-up word. In addition, this embodiment adds a plurality of optional implementation manners on the basis of the embodiment shown in fig. 1, and these optional implementation manners may be implemented in combination with each other or individually, and both can achieve the technical effect of enabling the user to select between the voice assistant of the application program and the system voice assistant, and being relatively simple and convenient to operate.
Referring to fig. 6, fig. 6 is a flowchart of another voice assistant wake-up method according to an embodiment of the present invention, which is applied to a mobile terminal. In this embodiment, on the basis of the embodiment shown in fig. 1, the step of receiving the first voice wake-up signal, the step of waking up the system voice assistant when the first voice wake-up signal matches with the preset wake-up word of the system voice assistant, and the step of waking up the voice assistant of the application program when the first voice wake-up signal matches with the preset wake-up word of the voice assistant of the application program are both refined, so that the problem of how to wake up the corresponding voice assistant when the mobile terminal receives two different voice wake-up signals input by a user in sequence is solved. As shown in fig. 6, the method comprises the steps of:
step 601, receiving a first voice awakening sub-signal and a second voice awakening sub-signal input by a user within a preset time length, wherein the receiving time of the first voice awakening sub-signal is prior to the receiving time of the second voice awakening sub-signal.
In practical applications, a scenario may occur in which the user continuously inputs two different voice wake-up signals, for example: the user expects to wake up the system voice assistant, but mistakenly inputs a first voice wake-up sub-signal 'hello, small B' matched with a preset wake-up word of the voice assistant of the application program, and immediately inputs a second voice wake-up sub-signal 'hello, small A' matched with the preset wake-up word of the system voice assistant after reaction.
Therefore, in this embodiment, the first voice wake-up sub-signal and the second voice wake-up sub-signal input by the user within a preset time period may be received, where the preset time period may be a time period preset by a system or a time period customized by the user, for example: and 3 seconds or 5 seconds and the like, wherein the receiving time of the first voice awakening sub-signal is prior to the receiving time of the second voice awakening sub-signal, namely, the user inputs the first voice awakening sub-signal firstly and then inputs the second voice awakening sub-signal.
Step 602, when the first voice wake-up sub-signal matches with a preset wake-up word of the voice assistant of the application program, and the second voice wake-up sub-signal matches with a preset wake-up word of the system voice assistant, waking up the system voice assistant.
Step 603, awakening the voice assistant of the application program under the condition that the first voice awakening sub-signal is matched with a preset awakening word of the system voice assistant and the second voice awakening sub-signal is matched with the preset awakening word of the voice assistant of the application program.
After receiving the first voice wake-up sub-signal and the second voice wake-up sub-signal input within the preset duration, the voice assistants matched with the first voice wake-up sub-signal and the second voice wake-up sub-signal may be detected respectively, and a specific detection manner may refer to a related implementation manner in the method embodiment shown in fig. 1, and is not described herein again to avoid repetition.
In this embodiment, if it is detected that the first voice wake-up sub-signal and the second voice wake-up sub-signal are respectively matched with the preset wake-up word of the voice assistant of the application program and the preset wake-up word of the system voice assistant, the voice assistant matched with the voice wake-up signal with the later receiving time can be woken up, i.e. when the first voice wake-up sub-signal matches a preset wake-up word of the voice assistant of the application, and awakens the system voice assistant under the condition that the second voice awakening sub-signal is matched with a preset awakening word of the system voice assistant, and awakening the voice assistant of the application program under the condition that the first voice awakening sub-signal is matched with a preset awakening word of the system voice assistant and the second voice awakening sub-signal is matched with the preset awakening word of the voice assistant of the application program.
Therefore, when the user continuously inputs different voice awakening sub-signals, the mobile terminal can awaken the voice assistant matched with the voice awakening sub-signal with the later receiving time, so that the voice assistant meeting the expectation of the user can be directly started without starting the voice assistant matched with the voice awakening sub-signal with the earlier receiving time, and the purpose of saving system resources is achieved.
In this embodiment, on the basis of the embodiment shown in fig. 1, the step of receiving the first voice wake-up signal, the step of waking up the system voice assistant when the first voice wake-up signal matches with a preset wake-up word of the system voice assistant, and the step of waking up the voice assistant of the application program when the first voice wake-up signal matches with the preset wake-up word of the voice assistant of the application program are both refined, so that the problem of how to wake up the corresponding voice assistant when the mobile terminal receives two different voice wake-up signals input by a user in sequence is solved. In addition, the embodiment can also achieve the technical effect that the user can select between the voice assistant of the application program and the system voice assistant, and the operation is simpler and more convenient.
