Detailed Description
In order to make the objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. Several embodiments of the invention are presented in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a first embodiment of the present invention provides a voice wake-up method for an intelligent device, which is applied to a plurality of intelligent devices, where the plurality of intelligent devices are connected to a same lan and are configured to join a same multicast network after being powered on, and the method includes the following steps.
S1, when a voice command sent by a user is received, extracting volume information of the voice command, and sending the volume information to each of other intelligent devices in the multicast network.
It should be noted that the intelligent device may be an intelligent sound box, an intelligent television, an intelligent air conditioner, a voice-operated switch, or the like.
In this embodiment, it is necessary to establish multicast between the voice receiving ends, which may be understood as accessing all the intelligent devices to the same local area network, or establishing wired connection or wireless connection between the intelligent devices, and when the intelligent devices are in wireless connection, bluetooth or WiFi may be used.
In actual operation, in order to manage each intelligent device, each intelligent device can be bound with one mobile phone at the same time, similar mobile phones are bound with Bluetooth sound boxes, and APP downloaded from the mobile phones is used for controlling the specific working state of each intelligent device. In this embodiment, each smart device is set to have only one device executing a voice command.
In this embodiment, a voice command is used to perform the wake-up operation, and in other embodiments, the wake-up operation may also be used to perform operations such as playing a video, adjusting a volume, and adjusting a wind speed.
S2, local volume information and external volume information are respectively acquired for any intelligent device, and the external volume information is volume information of the voice command received by each other intelligent device in the multicast network.
It should be noted that the volume information includes a volume value, one voice receiving end corresponds to one volume value, and the volume value can trace back the voice receiving end, when any volume value is obtained, the corresponding voice receiving end can be obtained by using the mapping relationship, so that it is convenient to subsequently and independently select a certain voice receiving end to execute a voice instruction.
It is understood that the volume information can be judged to be from the device or the external device by distinguishing the local volume information from the external volume information.
And S3, judging whether the local volume information is larger than the external volume information.
And S4, if yes, executing the voice command corresponding to the local volume information.
It can be understood that when the smart devices are close to each other, the same sound source can enable multiple smart devices to respond, in this case, volume information can be mutually sent among the smart devices, if 4 smart devices exist, when any one device receives voice information, volume information can be sent to the other 3 devices, and each smart device can receive 4 volume information (1 comes from itself, and 3 comes from other devices).
In addition, for a single intelligent device, if the volume of the voice command received by the intelligent device is larger than the volume of the voice command received by other devices, the intelligent device can be judged to be nearest to the user, and the voice command can be directly executed. For example, if the local device receives a volume of 30dB and the other devices receive volumes of 10dB, 15dB, and 20dB, respectively, the local volume information is greater than the external volume information, and the local device can be controlled to execute the voice command.
A second embodiment of the present invention provides a voice wake-up method for an intelligent device, which is applied to a plurality of intelligent devices, where the plurality of intelligent devices are connected to a same lan and form a multicast network after being powered on, and the method includes the following steps.
S1, when a voice command sent by a user is received, extracting volume information of the voice command, and sending the volume information to each of other intelligent devices in the multicast network.
In this embodiment, it is necessary to establish multicast between the voice receiving ends, which may be understood as accessing all the intelligent devices to the same local area network, or establishing wired connection or wireless connection between the intelligent devices, and when the intelligent devices are in wireless connection, bluetooth or WiFi may be used.
S2, local volume information and external volume information are respectively acquired for any intelligent device, and the external volume information is volume information of the voice command received by each other intelligent device in the multicast network.
And S3, judging whether the local volume information is larger than the external volume information.
And S31, starting timing, wherein the timing time is preset time, and when the timing is expired, stopping acquiring the external volume information.
It can be understood that the sending of the information requires a certain time, and the timing can prevent the system from waiting for a long time. In this embodiment, the preset time is 0.3 seconds, that is, the system automatically determines that the volume information sent by all the external devices has been received after 0.3 seconds. In other embodiments, the preset time may be set according to actual conditions.
In addition, if the timing is not set, a logic instruction needs to be additionally set to judge whether the volume information is completely received, and the logic instruction is complicated, so that the operation burden of the system is increased.
S32, obtaining a maximum volume value in the volume information of the voice command received by each of the other intelligent devices, and judging whether the local volume information is larger than the maximum volume value.
It should be noted that, the maximum value in the external volume information may be obtained first, and then the maximum value is compared with the size of the local volume information, so that the operation complexity is reduced, and the local device and the external device are not confused.
And S4, if yes, executing the voice command corresponding to the local volume information.
In this embodiment, when the local device starts executing, the other devices do not need to execute, and a sleep request may be sent to each of the other intelligent devices.
S41, whether the local volume information is smaller than the external volume information or not is judged, and a sleep request is sent to local intelligent equipment.
In this embodiment, after the user sends the wake-up instruction, each device picks up the sound sent by the user to the multicast announcement local machine, and if the received volume of each device is greater than the local volume, each device automatically exits, and if the local volume is greater than the received volume of other devices within 0.3 second, service work is started, and the voice work of the round is announced to be started, and other devices forcibly enter a rest state when receiving the work start announcement instruction.
And S42, acquiring voiceprint information in the voice information, and executing the voice command if the voiceprint information is matched with a preset voiceprint library.
In order to better control the intelligent device, a voiceprint library can be set, a user can input own voiceprint in the voiceprint library, similar to fingerprints, the user can only execute operation when the voiceprints in the sent voice command are matched, and the user can set a person capable of operating the intelligent device according to the method to prevent outsiders or children from accidentally giving instructions to the intelligent device.
In addition, the step of recognizing the voice command includes:
(1) recognizing each character voice in the voice information as corresponding characters and arranging the characters in sequence;
(2) acquiring a time interval between each character;
(3) for the adjacent characters, if the time interval is less than the preset time, combining the adjacent characters as key information;
(4) and inputting the key information into a preset information base to obtain a corresponding executable code, namely the voice instruction.
It should be noted that the method can improve the accuracy of speech recognition, especially for some sentences that are easy to be ambiguous under the condition of continuous sentence. The key information of this embodiment may be a keyword or a key sentence, and the preset information base is an executable code that is stored in the intelligent device itself or in a search engine on the server and can convert corresponding speech.
In addition, in order to save energy, the present embodiment also issues a sleep request to the voice receiving end other than the voice receiving end corresponding to the maximum value of the volume.
It can be understood that, for the intelligent device, if the volume information of the intelligent device is judged not to be the maximum volume value, the intelligent device can send a sleep request to the intelligent device while not executing the voice instruction, so that the intelligent device can be in a low-energy consumption state, and energy conservation is realized. In the prior art, the smart device is in a sleep state generally when not in use, and wakes up itself when receiving voice information.
The invention has the advantages that compared with the volume information received by each voice receiving end, the intelligent device with the maximum volume is independently selected to execute the voice command, and the other intelligent devices do not execute the voice command, so that each voice receiving end does not need to be arranged at a remote place or separated.
Referring to fig. 2, a third embodiment of the present invention provides a voice control system, including:
the volume transceiving module is used for extracting volume information of a voice command when receiving the voice command sent by a user and sending the volume information to each other intelligent device in the multicast network;
a volume obtaining module, configured to separately obtain, for any one of the smart devices, local volume information and external volume information, where the external volume information is volume information of the voice command received by each of the other smart devices in the multicast network;
the judging module is used for judging whether the local volume information is larger than the external volume information;
and the execution module is used for executing the voice command corresponding to the local volume information when the local volume information is larger than the external volume information.
It can be understood that the volume acquiring module is a sound receiver, and the determining module and the executing module can be integrated on a chip built in the smart device, and need to perform certain operations, and receive and send instructions.
In addition, in order to save energy consumption, the embodiment is further provided with an automatic sleep module, when the volume information of the intelligent device is not the maximum volume value, the intelligent device can send a sleep request to the intelligent device while not executing the voice instruction, and the power consumption of the intelligent device is reduced.
A fourth embodiment of the invention proposes a readable storage medium having stored thereon computer instructions which, when executed by a processor, implement the method of the first embodiment.
A fifth embodiment of the invention proposes an electronic device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, which when executing the program implements the method of the first embodiment.
