It should be noted that, after the voice data stream is acquired by the voice acquisition module 11, data filtering and encryption operations may be performed on the voice data stream to obtain a data stream to be transmitted, where the data filtering is to filter out noise, and the encryption is to ensure security of voice transmission. In the process of transmitting the data stream to be transmitted to the external control equipment, the voice transmission forbidding instruction sent by the external control equipment can be received at any time, the data stream to be transmitted is stopped being output at the moment, and the data stream to be transmitted can be stored in a memory built in the voice acquisition equipment.
In addition, the preset wake-up word in this embodiment may also be changed, specifically, the external control device may send a wake-up word replacement instruction, where the instruction carries an updated wake-up word, which is called a target wake-up word, and after receiving the instruction, the processing module 12 may respond to the wake-up word replacement instruction, and replace the preset wake-up word with the target wake-up word. And then, taking the target wake-up word as a wake-up basis.
In addition, the external control equipment has a function of controlling whether the collected voice is transmitted to the external control equipment, if characters of 'whether the collected voice is transmitted to the external control equipment' and two options of 'yes' and 'no' can be displayed in a display interface of the external control equipment, if the user selects 'yes' (a voice transmission instruction is generated at the moment), the collected voice is output to the external control equipment, and if the user selects 'no' (a voice transmission prohibition instruction is generated at the moment), the collected voice is not output to the external control equipment.
It can be seen from the above analysis that, only under the condition that the processing module 12 simultaneously exists the physical signal and the voice control instruction (the physical signal is received first, after the voice acquisition device communicates with the external control device, the voice control instruction sent by the external control device is received), the processing module 12 can respond to the voice control instruction, and whether the physical signal exists or not can be controlled by the user, so as to avoid the collected voice being stolen, the user can cut off the physical signal (the connection between the USB interface and the external control device is switched, or the hardware switch is controlled to be turned off, and the voice acquisition device stops working), at this moment, the voice acquisition device does not work, so that the voice cannot be acquired, further, the voice of the user can be prevented from being stolen, and the reliability of voice acquisition is improved. In addition, the disconnection mode is directly the physical connection between the voice acquisition equipment and the preset voice control equipment, and compared with a mode of controlling the voice acquisition equipment to stop working through software or a program, the disconnection mode is convenient and quick and has high effectiveness. In addition, the computing power of the external control equipment is greatly reduced, the development difficulty of the external control equipment is reduced, and the possibility of voice awakening, acquisition and parallel operation of other programs built in the external control equipment is ensured.
In the case that the data transmission module 13 is a USB interface, the preset voice control device (in this case, an external interface control device) in this embodiment may be a computer or a vehicle-mounted terminal. The voice acquisition equipment can be plugged in a computer and can also be plugged in a vehicle-mounted terminal, so that the recording of the user voice in different scenes is realized.
In another implementation manner of the present invention, referring to fig. 2, the voice collecting device may further include an indicator lamp 14, where the indicator lamp 14 may be an LED lamp, and the indicator lamp 14 is connected to the processing module 12. The indicator lamp 14 can be used for indicating the working state of the voice acquisition equipment, when the voice acquisition equipment is not connected with the external control equipment, the LED lamp is not on, when the voice acquisition equipment is connected with the external control equipment and the voice acquisition module 11 in the voice acquisition equipment acquires voice, the LED lamp flickers to remind a user of acquiring voice at the moment, and whether the voice acquisition equipment needs to be disconnected with the external control equipment is judged.
When the voice acquisition equipment is connected with external control equipment and the voice acquisition module 11 in the voice acquisition equipment does not acquire voice, namely when the user does not speak, the LED lamp is normally on, thereby reminding the user that the voice acquisition equipment does not execute voice acquisition operation.
It should be noted that, in this embodiment, when collecting voice, the LED lamp flickers, and when not collecting voice, the LED lamp is always on. In addition, the LED lamp can be set to be always on when voice is collected, and the LED lamp flashes in the absence of voice collection to distinguish any mode of collecting voice and the state of not collecting voice. Moreover, the working state of the LED lamp in this embodiment is only related to whether the voice acquisition module 11 acquires voice, and is unrelated to the working state of the external control device.
In this embodiment, indicator light 14 has been added to remind the operating condition of this pronunciation collection equipment of user, and then can further remind whether user's pronunciation collection equipment is gathering pronunciation, then when pronunciation collection equipment gathered pronunciation but the user does not want pronunciation this moment to be gathered, can break off pronunciation collection equipment and predetermine the connection of voice control equipment, switch foretell physical signal promptly to avoid user's pronunciation to be revealed and the loss that brings.
