Method and apparatus for reducing noise based on in vehicle multitone range, electronic equipment and storage medium

摘要

Problem to be solved: to provide a noise reduction method, an apparatus, an electronic apparatus and a storage medium based on an on vehicle multi tone range to avoid the phenomenon that the utilization rate of the CPU is reduced and the execution of the vehicle terminal is slow without affecting the speech recognition and interaction.The noise reduction method determines the target range of sound to which the voice signal that has been waked up by the vehicle mounted terminal is determined based on the voice signal acquired in each sound range by the corresponding noise reduction module corresponding to each sound range, and the noise reduction stop instruction is made It is transmitted to the noise reduction module of the other sound ranges other than the target range.The noise reduction stop instruction is used to instruct the noise reduction module in other sound ranges to turn off the noise reduction algorithm in the process of performing voice interaction with respect to the object range.Diagram
