It should be noted that the voice interaction method provided by the embodiment of the present application is generally executed by the intelligent terminal devices 101, 102, and 103. Accordingly, the voice interaction device is generally disposed in the intelligent terminal apparatus 101, 102, 103.
It should be understood that the number of intelligent end devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of intelligent end devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a voice interaction method according to the present application is shown. The voice interaction method of the embodiment comprises the following steps:
In this embodiment, the execution subject of the voice interaction method (for example, the intelligent terminal devices 101, 102, 103 shown in fig. 1) may monitor the voice of the user in real time. Specifically, the execution main body may be provided with a microphone array for collecting the voice of the user in real time and analyzing the voice.
After the execution main body collects the voice of the user, the voice can be recognized, and whether the voice comprises a first preset word or not is determined. Specifically, the execution main body may perform speech recognition on the speech to obtain a text corresponding to the speech. Then, whether the first preset word is included in the text is determined. Here, the first preset word may be a part of a wake-up word of the smart terminal device, and may be, for example, the first two words of the wake-up word. For example, the wake word is small a, and the first predetermined word may be small a.
In this embodiment, if the voice includes the first preset word, the execution main body may determine whether the context information located in the first preset word in the voice includes the second preset word. Here, the second preset word may be another part of the wake-up word, for example, the last two words of the wake-up word. It is understood that the first predetermined term and the second predetermined term may be the same or different.
In response to determining that the context information of the first preset word includes a second preset word, intent recognition is performed on the context information of the second preset word, step 204.
The execution subject may perform intent recognition on context information of a second preset word in the voice if the context information of the first preset word includes the second preset word. Specifically, the executing agent may perform intent recognition using an existing algorithm. For example, the executing body may input the following information of the second preset word in the speech into a preset intention recognition model, and output the intention recognition model as the recognized intention.
In step 205, the control device responds to the user based on the intent recognition result.
In this embodiment, the execution subject may control the device according to the intention recognition result to respond to the user. For example, if the intention recognition result is turning off the light, the execution subject may generate a turn-off command to turn off the light, thereby realizing a response to the user.
With continued reference to FIG. 3, a schematic diagram of one application scenario of the voice interaction method according to the present application is shown. In the application scenario of fig. 3, the user says "small a and small B turn off the light" to the smart speaker. After the intelligent sound box receives the voice, the voice is recognized to comprise a first preset word ' small A ', and the context information of the small A ' comprises a second preset word ' small B '. Then the following information "light off" of the second preset word "small B" is subject to intent recognition, resulting in the intent of "light off". Then, the smart speaker sends a turn-off command to the lamp to turn off the electric lamp.
The voice interaction method provided by the embodiment of the application enables the interaction process of the equipment to become more adaptive and user experience to be more friendly.
With continued reference to FIG. 4, a flow 400 of another embodiment of a voice interaction method according to the present application is shown. As shown in fig. 4, the voice interaction method of the present embodiment may include the following steps:
In step 403, in response to determining that the voice includes the first preset word, determining whether the context information located in the first preset word in the voice includes the second preset word.
In response to determining that the context information of the first preset word includes a second preset word, intent recognition is performed on the context information of the second preset word, step 404.
The principle of steps 401 to 404 is similar to that of steps 201 to 204, and is not described herein again.
In response to determining that the context information for the first preset term does not include the second preset term, intent recognition is performed on the context information for the first preset term, step 405.
In this embodiment, if the context information of the first preset word in the voice does not include the second preset word, the execution subject may perform intent recognition on the context information of the first preset word. If the context information of the first preset word does not include the second preset word, it indicates that the user likes to awaken the intelligent device by using the first two words of the preset awakening word, and the intent recognition can be performed on the context information of the first preset word.
And 406, controlling the equipment to respond to the user according to the intention recognition result.
In this embodiment, the execution subject may also determine the interaction habit of the user on the device according to the voice. Here, the interaction habit may be understood as a control instruction that is most often used when a user interacts with a device. For example, the interaction habit is a first preset word + an instruction, or a first preset word + a second preset word + a pause + an instruction.
In some optional implementation manners of this embodiment, the step 407 may be specifically implemented by the following steps not shown in fig. 4: in response to determining that the context information of the first preset word includes the second preset word, determining that a combination of the first preset word and the second preset word is a common wake-up word of the user for the device.
In this implementation manner, if it is determined that the context information of the first preset word includes the second preset word, the execution main body considers that the wake-up word used by the user is the first preset word + the second preset word. The execution subject may use a combination of the first preset word and the second preset word as a common wake-up word of the user for the device.
In some optional implementation manners of this embodiment, the step 407 may be specifically implemented by the following steps not shown in fig. 4: and in response to determining that the context information of the first preset word does not include the second preset word, determining that the first preset word is a common wake-up word of the user to the device.
In this implementation, if the execution main body determines that the context information of the first preset word does not include the second preset word, the execution main body determines that the user frequently uses the first preset word to wake up the device, and thus the first preset word may be used as a common wake up word of the device by the user.
In some optional implementation manners of this embodiment, the step 407 may be specifically implemented by the following steps not shown in fig. 4: from the speech, a dwell time after the common wake up word is determined.
In this implementation, the execution subject may also determine a dwell time after the wakeup word. If the pause time is long, the user can be responded to immediately, for example, the voice "I am" is output, in order to improve the user experience.
And step 408, outputting response information according to the interaction habit.
The execution subject may output the response information according to the interaction habit. For example, if the interaction habit is the first preset word + the second preset word + the pause + the instruction, the execution main body may immediately output the response information after the user has spoken the first preset word + the second preset word. Then, after the user speaks the instruction, the device is controlled.
According to the voice interaction method provided by the embodiment of the application, the response information can be output according to the interaction habit of the user to the equipment, the adaptability of the equipment is improved, and the user experience is improved.
