Embodiment 1
[0056] like figure 1 As shown, this embodiment provides a method for noise reduction in a call, including:
[0057] Step 1. When it is detected that the Bluetooth hands-free call has been connected, detect the status of the driver's window and the passenger's window.
[0058] Step 2. When it is detected that the window of the driver's seat and the window of the passenger's seat are open, acquire the information of the external environment noise and wind noise outside the car.
[0059] The wind noise is generated by the turbulence generated when the air flow passes through the microphone port or the microphone diaphragm, and the wind noise information outside the vehicle is acquired by the wind noise microphone.
[0060] External ambient noise refers to noise other than wind noise.
[0061] When a microphone is installed, the wind noise and the external environment noise can be identified based on the voice recognition algorithm according to the characteristics of the wind no...
Embodiment 2
[0095] like figure 2 As shown, the present embodiment provides a noise reduction device for talking, including:
[0096] A call monitoring module, a vehicle window position acquisition module, a noise acquisition module, a first execution module, a second execution module, and a prompt module connected to the judgment control module;
[0097] The call monitoring module is used to detect the call state of the bluetooth phone;
[0098] The vehicle window position acquisition module is used to acquire the status of the driver's window and the passenger's window;
[0099] The noise acquisition module is used to acquire external environment noise and wind noise;
[0100] The first execution module is used to control the lifting of the driver's window;
[0101] The second execution module is used to control the lifting and lowering of the window of the passenger seat;
[0102] The prompt module is used to output prompt information;
[0103] The judging control module is used t...

Abstract
The present invention provides a call noise reduction method and device. The method includes: after detecting that the Bluetooth hands-free call has been connected, detecting the status of the driver's window and the passenger's window; After the vehicle window is in the open state, the external environment noise and wind noise information outside the vehicle are obtained; according to the external environment noise and wind noise, the lifting of at least one of the driver's window and the passenger's window is controlled. The invention realizes automatic control of the up and down of the vehicle window under the condition that the vehicle window is not completely closed when encountering noisy environmental noise during the communication process, maintains the communication quality and improves the driving experience.
Description
technical field [0001] The present invention relates to the technical field of driving assistance, in particular to a method and device for noise reduction during conversations. Background technique [0002] At present, the in-vehicle infotainment system has become more and more popular in cars, enriching the journey experience of drivers and passengers. Among them, the Bluetooth hands-free function (HFP) enables the driver to complete the call with the other party through the in-vehicle infotainment system and the in-vehicle speaker . [0003] However, when the driver talks through HFP while driving with the window open, the noise inside and outside the car is too loud to hear the other party’s words clearly, which leads to a decline in the quality of the call. ACCIDENT. [0004] Therefore, the prior art needs to be further improved. Contents of the invention [0005] The present invention provides a call noise reduction method and device, which aims to solve the defec...
