我们提出了一种基于掩模的极低质量语音增强器,它能够通过识别包含重要语音能量的时频区域以抗噪声的方式保留重要线索。我们使用分类器从提供浊音和浊音的能量分布信息的输入特征集中估计时频掩码。我们在一系列有噪声的语音信号上评估了增强器,并证明它在客观可理解性度量方面产生了一致的改进。
We propose a mask-based enhancer for very low quality speech that is able to preserve important cues in a noise-robust manner by identifying the time-frequency regions that contain significant speech energy. We use a classifier to estimate a time-frequency mask from an input feature set that provides information about the energy distribution of both voiced and unvoiced speech. We evaluate the enhancer on a range of noisy speech signals and demonstrate that it yields consistent improvements in an objective intelligibility measure.
