Abstract

The present invention provides a method, system, vehicle-mounted equipment, and automobile for automatic adjustment of call volume, which are applied to automobiles. The automatic adjustment method for call volume includes: when the automobile enters the emergency call mode, collecting sound data signals in the emergency call mode ; preprocessing the sound data signal to obtain background noise data samples; real-time statistical analysis of the background noise data samples, and calculating the background noise intensity in the emergency call mode; The voice intensity matched with the above background noise intensity, and the current call volume is adjusted in real time according to the calculated voice intensity. The method for automatically adjusting the call volume of the invention can effectively suppress background noise, improve the clarity of call center personnel, ensure normal telephone communication between the user and the call center, and strive for the shortest rescue time for the user.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics and relates to an adjustment method and system, in particular to an automatic adjustment method and system for call volume, vehicle-mounted equipment and an automobile. Background technique [0002] T-Box is a very important component in today's connected car in-vehicle system, and its main function is to realize the interconnection between cars and TSP. Among the many services provided by T-Box, one is the emergency rescue call. Through this service, the drivers and passengers in the car use the speaker and microphone in the car to communicate with the call center to make emergency rescue requests. [0003] The engineer will adjust the volume and gain settings of the speaker in the T-Box drive car in the office, and after curing the parameters, provide the T-Box emergency rescue call to the end customer. When the actual end user calls for emergency rescue, the background noise is ...
