摘要翻译：
尽管自动语音识别技术取得了显著的进展，但识别混杂着各种噪声源的远场语音仍然是一项具有挑战性的任务。本文介绍了一种新颖的师生迁移学习方法BridgeNet，它为提高远程语音识别能力提供了一种解决方案。BridgeNet中有两个关键特性。首先，BridgeNet通过提供来自教师网络的多种提示扩展了传统的学生-教师框架。暗示并不局限于来自教师网络的软标签。教师的中间特征表示可以更好地指导学生网络学习如何去噪或去混杂噪声输入。其次，所提出的桥接网中的递归结构可以迭代地提高去噪和识别性能。实验结果表明，BridgeNet在解决远距离语音识别问题上有显著的改进，与无教师提示的基线神经网络相比，它在AMI语料上的相对WER减少了13.24%。

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：
  Despite the remarkable progress achieved on automatic speech recognition, recognizing far-field speeches mixed with various noise sources is still a challenging task. In this paper, we introduce novel student-teacher transfer learning, BridgeNet which can provide a solution to improve distant speech recognition. There are two key features in BridgeNet. First, BridgeNet extends traditional student-teacher frameworks by providing multiple hints from a teacher network. Hints are not limited to the soft labels from a teacher network. Teacher's intermediate feature representations can better guide a student network to learn how to denoise or dereverberate noisy input. Second, the proposed recursive architecture in the BridgeNet can iteratively improve denoising and recognition performance. The experimental results of BridgeNet showed significant improvements in tackling the distant speech recognition problem, where it achieved up to 13.24% relative WER reductions on AMI corpus compared to a baseline neural network without teacher's hints.
