摘要:

本文介绍了我们在Interspeech COMPARE Challenge 2020中的面罩和呼吸子挑战的方法。对于面具检测任务,我们训练具有滤波器组能量、性别感知特征和说话者感知特征的深度卷积神经网络。支持向量机作为后端分类器,用于对提取的深度嵌入进行二进制预测。为了增加训练数据的数量和提高模型的鲁棒性,我们使用了几种数据增强方案,包括速度扰动、SpecAugment和随机擦除。对于语音呼吸监测任务,我们研究了基于Bi-LSTM结构的不同瓶颈特征。实验结果表明,我们提出的方法优于基线,并实现0.746 PCC和78.8%的UAR的呼吸和面具评估集,分别。

英文摘要:

This paper introduces our approaches for the Mask and Breathing Sub-Challenge in the Interspeech COMPARE Challenge 2020. For the mask detection task, we train deep convolutional neural networks with filter-bank energies, gender-aware features, and speaker-aware features. Support Vector Machines follows as the back-end classifiers for binary prediction on the extracted deep embeddings. Several data augmentation schemes are used to increase the quantity of training data and improve our models' robustness, including speed perturbation, SpecAugment, and random erasing. For the speech breath monitoring task, we investigate different bottleneck features based on the Bi-LSTM structure. Experimental results show that our proposed methods outperform the baselines and achieve 0.746 PCC and 78.8% UAR on the Breathing and Mask evaluation set, respectively.
