摘要翻译：
近年来神经自回归模型的发展提高了语音合成(SS)的性能。然而，由于神经自回归SS系统缺乏对语音的全局特征（如说话人的个性或说话风格）建模的能力，特别是在这些特征没有被标记的情况下，如何使神经自回归SS系统更具表现力仍然是一个开放的问题。本文提出将自回归SS模型VoiceLoop与变分自动编码器(VAE)相结合。与传统的自回归SS系统不同，该方法使用VAE显式建模全局特征，使得合成语音的表现力可以在无监督的情况下得到控制。利用VCTK和Blizzard2012数据集进行的实验表明，VAE通过在语音生成过程中引入全局特征，帮助VoiceLoop生成更高质量的语音，并控制其合成语音中的表达式。

一级分类：Computer Science        计算机科学
二级分类：Computation and Language        计算与语言
分类描述：Covers natural language processing. Roughly includes material in ACM Subject Class I.2.7. Note that work on artificial languages (programming languages, logics, formal systems) that does not explicitly address natural-language issues broadly construed (natural-language processing, computational linguistics, speech, text retrieval, etc.) is not appropriate for this area.
涵盖自然语言处理。大致包括ACM科目I.2.7类的材料。请注意，人工语言（编程语言、逻辑学、形式系统）的工作，如果没有明确地解决广义的自然语言问题（自然语言处理、计算语言学、语音、文本检索等），就不适合这个领域。

英文摘要：
  Recent advances in neural autoregressive models have improve the performance of speech synthesis (SS). However, as they lack the ability to model global characteristics of speech (such as speaker individualities or speaking styles), particularly when these characteristics have not been labeled, making neural autoregressive SS systems more expressive is still an open issue. In this paper, we propose to combine VoiceLoop, an autoregressive SS model, with Variational Autoencoder (VAE). This approach, unlike traditional autoregressive SS systems, uses VAE to model the global characteristics explicitly, enabling the expressiveness of the synthesized speech to be controlled in an unsupervised manner. Experiments using the VCTK and Blizzard2012 datasets show the VAE helps VoiceLoop to generate higher quality speech and to control the expressions in its synthesized speech by incorporating global characteristics into the speech generating process.
