摘要翻译：
以无监督的方式学习数据的潜在表示是一个非常有趣的过程，它为提高分类器的性能提供了相关的特征。对于语音情感识别任务，有效特征的生成至关重要。目前，语音情感识别大多采用手工特征，而利用深度学习自动学习的特征在许多问题上取得了很大的成功，尤其是在图像处理方面。特别是，像变分自动编码器（VAEs）这样的深度生成模型在自然图像特征生成方面取得了巨大的成功。受此启发，我们提出了VAEs来推导语音信号的潜在表示，并将其用于情感分类。据我们所知，我们是第一个提出语音情感分类的VAEs。对IEMOCAP数据集的评价表明，VAEs学习的特征可以产生最先进的语音情感分类结果。

英文摘要：
  Learning the latent representation of data in unsupervised fashion is a very interesting process that provides relevant features for enhancing the performance of a classifier. For speech emotion recognition tasks, generating effective features is crucial. Currently, handcrafted features are mostly used for speech emotion recognition, however, features learned automatically using deep learning have shown strong success in many problems, especially in image processing. In particular, deep generative models such as Variational Autoencoders (VAEs) have gained enormous success for generating features for natural images. Inspired by this, we propose VAEs for deriving the latent representation of speech signals and use this representation to classify emotions. To the best of our knowledge, we are the first to propose VAEs for speech emotion classification. Evaluations on the IEMOCAP dataset demonstrate that features learned by VAEs can produce state-of-the-art results for speech emotion classification.
