Abstract

The invention relates to a method and system for adjusting a conversion volume dynamically by using a noise-reducing microphone. The method comprises: after a conversion terminal is detected to be in a conversion state, a noise-reducing microphone of the conversion terminal is turned on; the noise-reducing microphone detects an environment noise value within set time and calculates an average environment noise value within the set time; according to a preset correspondence relation, an ideal conversion volume corresponding to the average environment noise value is determined; and on the basis of the ideal conversion volume, a receiver output volume of the conversion terminal is adjusted automatically. According to the invention, the noise-reducing microphone of the conversion terminal is used for collecting the environment noise, so that no extra hardware needs to be added; and because the receiver output volume is adjusted dynamically according to the noise value, the influence on the conversion quality by the noisy environment can be avoided under the circumstance that the hand-operated intervention from the user is not required, so that an objective that the normal conversion demand of the user can be satisfied in silent or noisy environment.

Description

technical field [0001] The present invention relates to the technical field of call terminal processing, in particular to a method and system for dynamically adjusting call volume by using a noise reduction microphone. Background technique [0002] Current smartphones are generally equipped with noise-canceling microphones, which can be used to process the background noise of the sender during a call through technical means, thereby improving the quality of the call. However, if the background noise of the receiving party is relatively large during the call, even if the sending party has performed noise reduction processing, it is difficult to hear the content of the call, and the user can only manually increase the output volume of the earpiece. In many scenes, background noise changes in real time, such as streets. The user talks while walking on the street. When there are many people on the street and the noise is loud, the user needs to manually adjust the volume of the...
