摘　　要：语音降噪是信号处理领域的一个重要研究方向,旨在提高语音信号在噪声环境中的清晰度。时频域变换技术为语音降噪提供了有效的解决方案。通过将信号从时间域转化到频率域,能够同时获得时间和频率的信息,使得噪声的抑制和语音的保留更加精准。基于此,深入探讨时频域变换的基本概念,分析不同的时频域降噪技术,以及这些技术在实际语音降噪中的实现方法与效果评估。实验结果证明了时频域变换技术在语音降噪中的有效性。Speech noise reduction is a key research area in signal processing,aimed at enhancing speech clarity in noisy environments.Time frequency domain transformation technology provides an effective solution for speech noise reduction.By converting signals from the time domain to the frequency domain,both time and frequency information can be obtained simultaneously,making noise suppression and speech preservation more accurate.Based on this,this paper explores the core concepts of time frequency transformation,reviews various noise reduction methods,and assesses their implementation and effectiveness in real-world applications.Experimental results confirm the effectiveness of these techniques in speech noise reduction.
