The preset wake-up words are used for waking up the voice control function of the terminal device 100. The preset wake-up words may be a word, a sentence, or the like, and may be specifically set according to actual requirements, which is not particularly limited herein. For example, the preset wake-up word may be "small Q".
In one embodiment of the present application, the wakeup words recognition unit 12 may send an interrupt signal to the control unit 13 when determining that the voice signal includes a preset wakeup word. In another embodiment of the present application, when determining that the voice signal does not include the preset wake-up word, the wake-up word recognition unit 12 may not respond to the voice signal, and continue to receive the voice signal from the voice acquisition unit 11 until it is recognized that the voice signal includes the preset wake-up word, and send an interrupt signal to the control unit 13.
In a specific application, the wakeup words recognition unit 12 may send an interrupt signal to the control unit 13 by means of a hardware interrupt, or may send an interrupt signal to the control unit 13 by means of a software interrupt. The specific setting can be according to the actual demand, and is not particularly limited herein.
After the wakeup word recognition unit 12 sends the interrupt signal to the control unit 13, if the voice signal from the voice acquisition unit 11 is received again, the voice signal may be converted into a corresponding voice command, and the voice command may be sent to the control unit 13. The voice signal is an analog signal, the voice command is a digital signal corresponding to the voice signal, and the wakeup words recognition unit 12 may perform analog-to-digital conversion on the voice signal to obtain the voice command corresponding to the voice signal.
In the embodiment of the present application, the control unit 13 is configured to start monitoring the voice instruction from the wakeup word recognition unit 12 when receiving the interrupt signal, and generate a control instruction corresponding to the voice instruction when receiving the voice instruction.
In one possible implementation, the control instruction may include a control instruction for the terminal device itself, for example, a motion instruction. The motion instruction may include a motion parameter of the terminal device, for example, a motion route, a motion speed, and/or a rotation angular speed of the terminal device. In this implementation, the terminal device 100 can implement control of itself by executing the control instruction.
In another possible implementation, the control instruction may include a control instruction for another device connected to the terminal device. In this implementation, the control unit 13 may send a control instruction to the other device to implement control of the other device.
In a specific application, the control unit 13 may include a Micro Controller Unit (MCU), a single chip microcomputer (scm), an Advanced reduced instruction microprocessor (ARM), or the like, and may be specifically set according to an actual requirement, which is not particularly limited herein.
As can be seen from the above, in the terminal device based on voice control provided in this embodiment, the wakeup word recognition unit for recognizing the voice signal is arranged between the voice acquisition unit and the control unit, and when the wakeup word recognition unit recognizes that the voice signal includes the preset wakeup word, an interrupt signal is sent to the control unit; the control unit starts to monitor the voice command from the awakening word recognition unit after receiving the interrupt signal, namely the awakening word monitoring operation in the application is completed by the awakening word recognition unit, and the control unit starts the voice recognition function after the awakening word recognition unit monitors the preset awakening word, so that more processing resources of the control unit cannot be occupied, the resource utilization rate of the control unit is improved, and the power consumption of the control unit is reduced.
Please refer to fig. 2, which is a schematic structural diagram of a terminal device based on voice control according to another embodiment of the present application. As shown in fig. 2, the difference between the present embodiment and the corresponding embodiment of fig. 1 is that the voice collecting unit 11 in the present embodiment may be a microphone array composed of a plurality of microphones (microphone 1 to microphone n). For example, the plurality of microphones may be arranged linearly, and every two adjacent microphones are spaced apart by a certain distance. Of course, the plurality of microphones may be arranged in other ways.
It is understood that the difference in the arrangement positions of the different microphones may cause the voice signals from the same sound source to arrive at the different microphones at different times. Therefore, the position range where the sound source is located can be calculated using the time information when the voice signal reaches each microphone and the position information of each microphone.
In this embodiment, the microphone transmits the voice signal to the wakeup word recognition unit 12 and also transmits the time when the microphone acquires the voice signal. The awakening speech recognition unit 12 can calculate the position range of the sound source according to the time of collecting the speech signal by each microphone and the position information of each microphone, and then perform speech enhancement processing on the speech signal in the position range, and filter the speech signal outside the position range. Wherein the position information of the respective microphones can be stored in the wake-up language recognition unit 12.
According to the embodiment, the microphone array is adopted to collect voice signals, the sound source is positioned by means of the strong directivity of the microphone array, the voice signals in the position range where the sound source is located are enhanced, signals outside the position range where the sound source is located are filtered, accordingly, the interference of environment noise to the voice signals can be reduced, the accuracy of voice recognition of the terminal equipment is improved, and voice control is accurate.

In this embodiment, the control unit 13 is configured to send a control instruction to the communication unit 15 when the control instruction is a control instruction for a controlled device. The communication unit 15 is configured to receive a control instruction from the control unit 13 and transmit the control instruction to the controlled device.
In this embodiment, since the control unit 13 needs to send the control instruction to the controlled device connected to the terminal device, the control unit 13 needs a communication protocol between the terminal device and the controlled device when generating the control instruction, that is, a data structure of the control instruction generated by the control unit 13 needs to meet the requirement of the communication protocol.
In one possible approach, the data structure of the control instructions may be as shown in table 1 below.
TABLE 1
| Data head | Data length | Function code | Data bit | Check bit |
| Byte0，Byte1 | Byte2 | Byte3 | Byte4-Byte n | Byte n+1 |

When the function code is hexadecimal number 0x08, it indicates that the function code is used to implement the control function for the video monitor.
The data bits are used to record the valid control content. The effective control content is used to describe the manner of control over the target device, i.e., how the target device is controlled. The length of the data bits is different according to different control contents, and may be determined according to actual requirements, and the length of the data bits is not particularly limited herein. The target device may be the terminal device 100 itself, or may be a controlled device connected to the terminal device 100.
The check code is used for verifying the validity of the control instruction. The check code may be generated based on a preset check code generation policy. For example, the check code generation policy may be: starting from a first byte of the control instruction, carrying out XOR operation on the first byte and a second byte in the control instruction to obtain a first XOR value; performing XOR operation on the first XOR value and the third byte to obtain a second XOR value; and repeating the steps until the n-1 th exclusive-or value is obtained, and taking the n-1 th exclusive-or value as a check code.
After the controlled device receives the data, the controlled device may identify the control instruction through the data header, and then identify whether the control instruction is for the current controlled device itself based on the function code in the control instruction. And if the control instruction is specific to the current controlled equipment, verifying the validity of the control instruction based on the check code in the control instruction, and realizing corresponding control based on the data bit in the control instruction after determining that the control data is valid.
