舰船噪声环境下改进语音信号增强算法
Study of speech enhancement in the background of ship-radiated noise
摘要
Abstract
Spectral subtraction is wildly used in speech enhancement . But it is not always available in the ship working environment because of the fact that it is hard to discriminate the speech duration with the ship noise . So , in this paper , we propose a new approach , which first computes the frequency spectrum similarity and then discriminates the signal segments into speech or noise roughly . And then by the frame shifting method , we achieve a high discrimination precision . Finally , the improved algorithm is benchmarked on a large measured data and experimental results show that the proposed method can be used in various ship‐radiated noise environments . The discrimination accuracy is 98% for ship‐radiated noise and 96% for speech .关键词
