證券之星消息，根據天眼查APP數據顯示科大訊飛（002230）新獲得一項發明專利授權，專利名為“語音增強方法、計算機設備及存儲介質”，專利申請號為CN202111677651.0，授權日為2025年4月4日。

Patent abstract: the present application relates to the field of speech processing technology, and discloses a speech enhancement method, computer equipment and storage medium, by extracting the speech signal in the target scene, the first acoustic feature signal in the speech signal is input into the trained speech enhancement model for speech enhancement, after obtaining the first target acoustic feature signal, the phase of the first target acoustic feature signal and the first acoustic feature signal is synthesized to obtain the target voice signal; Because the trained speech enhancement model comprises a preset number of short-term memory modules, the preset number of short-term memory modules are stacked into a network structure with a stacked structure, and the loss function of the network structure with a stacked structure comprises a frequency domain loss part, a signal constraint loss part and a cross-domain constraint loss part, the trained speech enhancement model performs speech enhancement on the first acoustic feature information, which can not only suppress or eliminate stationary noise and non-stationary noise, but also suppress or eliminate impact noise.

今年以來科大訊飛新獲得專利授權168個，較去年同期增加了1.82%。結合公司2024年中報財務數據，2024上半年公司在研發方面投入了19.33億元，同比增27.4%。
