Speech enhancement plays a fundamental role in many applications such as teleconferencing systems, speech recognizers, human-machine interfaces, hands-free communications, mobile phones, and hearing aids. Indeed, the noise is around us and everywhere. So when a signal of interest (usually speech) is picked up by a microphone, it is always contaminated by noise, reverberation, and other undesired signals. The objective is then to clean up the noisy signal with digital signal processing tools without damaging much the desired speech signal.

语音增强在电话会议系统、语音识别器、人机界面、免提通信、移动电话和助听器等许多应用中发挥着基础作用。事实上，噪音就在我们周围，无处不在。因此，当麦克风拾取感兴趣的信号（通常是语音）时，它总是受到噪声、混响和其他不需要的信号的污染。目标是使用数字信号处理工具清除噪声信号，而不会对所需的语音信号造成太大损害。
