摘要:

INTERSPEECH 2020深度噪声抑制(DNS)挑战赛旨在促进实时单通道语音增强的合作研究,旨在最大限度地提高增强语音的主观(感知)质量。评价噪声抑制方法的一种典型方法是在通过分裂原始数据集获得的测试集上使用客观度量。虽然在合成测试集上性能良好,但在真实记录上模型性能通常会显着下降。此外,大多数传统的客观指标与主观测试没有很好的相关性,并且实验室主观测试对于大的测试集是不可扩展的。在这项挑战中,我们开源了一个大型的干净语音和噪声语料库,用于训练噪声抑制模型和一个代表性的测试集,用于由合成和真实录音组成的真实场景。我们还开源了一个基于ITU-T P.808的在线主观测试框架,供研究人员可靠地测试其开发。我们使用P.808在盲测集上评估了结果。讨论了挑战的结果和主要经验教训。数据集和脚本可以在这里找到,以便快速访问https://github.com/microsoft/DNS-Challenge。

英文摘要:

The INTERSPEECH 2020 Deep Noise Suppression (DNS) Challenge is intended to promote collaborative research in real-time single-channel Speech Enhancement aimed to maximize the subjective (perceptual) quality of the enhanced speech. A typical approach to evaluate the noise suppression methods is to use objective metrics on the test set obtained by splitting the original dataset. While the performance is good on the synthetic test set, often the model performance degrades significantly on real recordings. Also, most of the conventional objective metrics do not correlate well with subjective tests and lab subjective tests are not scalable for a large test set. In this challenge, we open-sourced a large clean speech and noise corpus for training the noise suppression models and a representative test set to real-world scenarios consisting of both synthetic and real recordings. We also open-sourced an online subjective test framework based on ITU-T P.808 for researchers to reliably test their developments. We evaluated the results using P.808 on a blind test set. The results and the key learnings from the challenge are discussed. The datasets and scripts can be found here for quick access https://github.com/microsoft/DNS-Challenge.
