Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As in the embodiment shown in fig. 1, a voice pickup system includes a bluetooth mouse 4, a bluetooth transceiver 2, and a master bluetooth voice transmitter 3; in the embodiment, an auxiliary microphone 5, an auxiliary Bluetooth voice transmitter and a voice button 6 are arranged in the Bluetooth mouse 4, the auxiliary Bluetooth voice transmitter is in communication connection with the Bluetooth transceiver through wireless Bluetooth, and the Bluetooth mouse 4 is in communication connection with the PC 1 to transmit voice data and button data; in the embodiment, the Bluetooth transceiver 2 is connected with the PC computer through a USB port; in this embodiment, the main bluetooth voice transmitter 3 is a bluetooth headset and is internally provided with a main microphone 7, and the main bluetooth voice transmitter 3 is in communication connection with the bluetooth transceiver 2 through wireless bluetooth to transmit voice data. The PC computer 1 is in communication connection with the cloud server through the Internet to transmit voice data and text data. Additionally, other embodiments of the master bluetooth voice transmitter: is a Bluetooth collar clip microphone. Bluetooth headsets may be headset, in-ear, etc. The voice button on the Bluetooth mouse is an entity button, the function of turning on and starting the main microphone of the main Bluetooth voice transmitter can be realized, and if the main Bluetooth voice transmitter is not turned on, no response is generated by pressing or related prompts can be given on a display screen of a PC (personal computer) through an application program.
Specifically, the noise reduction scheme of the main bluetooth voice transmitter adopts the method of picking up the voice only within a specified distance and included within a specified angle; the voice signals with longer distance and out of the set angle range are filtered. The effective speech angle is generally set to 45 degrees from the pickup reference point, but is not limited to 45 degrees; the effective speech distance can be set to 50cm in general, but is not limited to 50 cm. And can be adjusted according to the application of the product and the specific needs of the user. The effective voice angle is a cone area which takes the axis of the main microphone as the axis, takes the receiving end point of the main microphone as the starting point, forms an angle of 45 degrees with the axis and surrounds the axis to form an angle of 45 degrees, and is the effective voice angle.
The embodiment shown in fig. 3, a manually switched voice pick-up based text input system, which employs a voice pick-up system as described above; when a user needs to input characters, a voice button on a mouse is pressed, an MCU on the mouse sends a button instruction to a Bluetooth transceiver through wireless Bluetooth, the Bluetooth transceiver receives the instruction from the mouse and then sends an instruction for opening a main microphone to a main Bluetooth voice transmitter, the main Bluetooth voice transmitter receives the instruction and then opens the main microphone for internal pickup, the main microphone picks up voice and then performs operation noise reduction, and then the noise-reduced audio is transmitted back to the Bluetooth transceiver through Bluetooth; the voice received by the Bluetooth receiver is transmitted to the external intelligent equipment, and an application program preset in the external intelligent equipment transmits the voice to a specified cloud server for analysis; the cloud server converts the voice into a text and then sends the text back to the external intelligent device, and the application program of the external intelligent device displays the received text at a specified position, for example, an editing position indicated by a mouse cursor on a display screen. Because main bluetooth voice transmitter can wear at the ear or place on user's collar, it is very close to people's oral cavity, the pronunciation quality of picking up of the vice microphone of mouse built-in is better, and the degree of restitution of pronunciation audio frequency is also higher. On the basis, the main Bluetooth voice transmitter filters the environmental noise and the far and near voices of other people through the audio frequency after noise reduction processing, and the accuracy of converting the audio frequency into the characters is higher. The application program is used for uploading the voice data collected through the USB port to the cloud server, receiving the voice-to-text data returned by the cloud server, and providing a user interface for operation of a user or direct display of a text.
The embodiment shown in fig. 2, an automatically switched speech picking-up based text input system, which employs a speech picking-up system as described above; when the main Bluetooth voice transmitter is not started, a secondary microphone in the mouse picks up voice, and the voice picked up by the secondary microphone is subjected to noise reduction processing and then transmitted to the Bluetooth transceiver; when the main Bluetooth voice transmitter is started, a main microphone in the main Bluetooth voice transmitter picks up voice, and the voice picked up by the main microphone is subjected to noise reduction processing and then transmitted to the Bluetooth transmitter; the voice received by the Bluetooth receiver is transmitted to the external intelligent equipment, and an application program preset in the external intelligent equipment transmits the voice to a specified cloud server for analysis; the cloud server converts the voice into a text and then sends the text back to the external intelligent device, and the application program of the external intelligent device displays the received text on a specified position, for example, a display screen. The quality of the voice audio processed by the main Bluetooth voice transmitter is superior to the voice audio sampled by the auxiliary microphone in the mouse, so that when the main Bluetooth voice transmitter is started, the main Bluetooth voice transmitter is defaulted to be used as a preferential voice pickup.
The above embodiments are merely illustrative and not restrictive, and all equivalent changes and modifications made by the methods described in the claims are intended to be included within the scope of the present invention.
