Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the 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.
According to an embodiment of the present invention, a method for controlling speech is provided, as shown in fig. 1, which is a flow chart of an embodiment of the method of the present invention. The voice control method may include: step S110 to step S140.
At step S110, a current voice command is obtained, and a time interval between the current voice command and a previous voice command is obtained.
Optionally, the obtaining of the current voice instruction in step S110 may include: and acquiring the current voice instruction acquired by the voice acquisition module.
The voice acquisition module is arranged on any one of a device side to be reminded, an environment to which the device to be reminded belongs and a client side; and/or, the voice acquisition module may include: a microphone.
Therefore, the convenience and flexibility of the user for controlling the equipment to be controlled by using the voice data are improved by the aid of the current voice instruction sending modes in various forms.

The time recording module is arranged on any one of a side to be reminded of equipment, an environment to which the equipment to be reminded belongs and a client side.
Therefore, the convenience and flexibility of the user for controlling the equipment to be controlled by using the voice instruction are improved by the acquisition mode of the time intervals in various forms.
At step S120, it is determined whether the time interval exceeds a preset threshold.
For example: when a user issues a voice control instruction, if a wake-up word is not used, firstly, according to the record of the voice instruction recording module, the time interval between the instruction and the previous instruction is judged (the previous instruction is an executed effective instruction, and only the effective instruction can be recorded).
At step S130, if the time interval does not exceed the preset threshold, it is determined whether the control functions of the current voice command and the previous voice command are the same. In a specific using process, if the actual interval exceeds the preset threshold, a wakeup word needs to be input again to wake up the voice service of the device to be controlled, and then the current voice instruction is sent.
For example: if the interval duration does not exceed the preset threshold, the voice instruction analysis module analyzes the voice of the user to obtain the control action of the voice instruction, the voice instruction classification module determines the equipment function block pre-controlled by the instruction according to the control action, and if the function block and the function block of the previous instruction belong to the same function block, whether the instruction carries the previous instruction or the control instruction of the same type as the previous instruction can be judged. At this time, even if the user does not use the voice wake-up word, the device can still be controlled to execute the command action.
Optionally, with reference to a flowchart illustrating an embodiment of determining whether the control functions of the current voice instruction and the previous voice instruction are the same in the method of the present invention shown in fig. 2, a specific process of determining whether the control functions of the current voice instruction and the previous voice instruction are the same in step S130 may include: step S210 to step S240.
And step S210, analyzing the pre-control action of the current voice command.
For example: parsing the voice instructions may include: after the microphone receives the voice of the user, the voice characteristics of the user are extracted, an acoustic model is generated through algorithm learning, and the acoustic model is matched with the voice characteristics to obtain a recognition result.
And step S220, determining the current function block of the equipment to be controlled pre-controlled by the current voice command according to the pre-control action.
In step S230, it is determined whether the current functional block and the functional block controlled by the previous voice command are the same functional block.
Step S240, if the current functional block and the functional block controlled by the previous voice instruction are the same functional block, determining that the control functions of the current voice instruction and the previous voice instruction are the same.
Therefore, the current function block is determined based on the pre-control action of the current voice command, and the control functions of the current function block and the function block controlled by the previous voice command are determined to be the same under the condition that the current function block and the function block controlled by the previous voice command are the same, so that the determination mode is simple and convenient, and the reliability of the determination result is good.
In the same functional block, the current voice instruction receives the last voice instruction, or the current voice instruction and the last voice instruction belong to the same type of control instruction.
For example: in some specific scenarios, the voice command is accepted by the previous command, or the voice command and the previous command belong to the same type of command, that is, the command and the previous command control the same device function block.
From this, through setting up the multiple control situation in the same functional block, can convenience of customers directly control and remove the operation of awakeing from to the control command in the same functional block, promote convenience and the high efficiency that the user used, and the good reliability.
In step S140, if the current voice command has the same control function as the previous voice command, the current voice wakeup word is omitted, and the current voice command is executed according to the control function. In a specific using process, if the control functions of the current voice instruction and the previous voice instruction are different, the current voice instruction is continuously acquired, and the time interval between the current voice instruction and the previous voice instruction is acquired, or the voice service of the device to be controlled needs to be awakened again, and the current voice instruction is sent again.
For example: in order to facilitate the control operation of a user, the user can control the equipment without a wakeup word under the scenes, and the user can omit the wakeup word to control the equipment when a voice command issued by the user and a function block controlled by the previous voice command belong to the same function block of the equipment within a certain time interval; the user control operation is simplified, and the user experience is improved.
Therefore, in the time interval of the preset threshold value, if the control function of the current voice instruction is the same as that of the previous voice instruction, the voice awakening word is omitted, the current voice instruction is directly executed, the control flow is simplified, and the use convenience of a user is improved.
In an alternative embodiment, the method may further include: the process of recording voice commands and voice time.
The following further describes a specific process of recording the voice command and the voice time with reference to a flowchart of an embodiment of recording the voice command and the voice time in the method of the present invention shown in fig. 3, which may include: step S310 to step S340.
Step S310, voice data is obtained, and voice content and obtaining time of the voice data are recorded. The voice data may include: voice wake-up words and/or voice instructions.
Step S320, determining whether the voice data is executed by the device to be controlled.
Step S330, if the voice data is executed by the device to be controlled, marking a function block of the device to be controlled, which is pre-controlled by the voice instruction in the voice data, in the recorded voice content.
Or, in step S340, if the voice data is not executed by the device to be controlled, deleting the record of the voice data.
For example: in the voice control method of the automatic matching device, the matching rule may include: the user is provided with a control record, a household appliance function library and a user history control record.
For example: the voice instruction recording module: the user's voice is entered and the voice moment is recorded (whether the user has spoken the wake-up word or not), and if the voice is not eventually executed, the voice recording is deleted. The voice instruction analysis module: and analyzing the voice command to obtain the control action of the voice command. The voice instruction classification module: and marking the equipment function block pre-controlled by the voice instruction in the voice instruction recording module according to the control action of the voice instruction. When the next control instruction is input, the history library is searched, the time given by the previous instruction is matched with the control function block, and if the condition is met, the awakening word can be omitted.
Therefore, the voice data executed by the equipment to be controlled is recorded in advance, and the function blocks of the voice instruction and the control action are marked, so that whether the control function of the next voice instruction belongs to the same function block or not is determined conveniently by referring to the function blocks, and convenience and reliability of simplifying the control process based on historical use records of a user are improved.
Through a large number of tests, the technical scheme of the embodiment is adopted, and when the voice command issued by the user and the function block controlled by the previous voice command belong to the same function block of the equipment within a certain time interval, the user can omit the awakening word control equipment, so that the user control operation is simplified.
