摘要翻译：
多语种和跨语种语音识别技术可以在资源不足的情况下帮助引导系统，并能够分析新的语言和领域。端到端方法，特别是基于序列的技术，由于其简单和优雅而很有吸引力。虽然可以集成传统的多语言瓶颈特征提取器作为前端，但我们证明了序列模型的端到端多语言训练对于使用连接主义时态分类(CTC)损失训练的上下文无关模型是有效的。我们表明，我们的模型在Babel语言上的性能绝对提高了6%以上，就单词/音素错误率而言，与构建在相同设置中的单语言系统相比，这些语言的性能绝对提高了6%以上。我们还表明，训练后的模型只需使用25%的目标数据就可以跨语言地适应一种看不见的语言。我们表明，多语言培训对于资源非常低的跨语言目标场景非常重要，但对于多语言测试场景则不重要。在这里，包含大量准备充分的数据集似乎是有益的。

分类信息：

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：
  Techniques for multi-lingual and cross-lingual speech recognition can help in low resource scenarios, to bootstrap systems and enable analysis of new languages and domains. End-to-end approaches, in particular sequence-based techniques, are attractive because of their simplicity and elegance. While it is possible to integrate traditional multi-lingual bottleneck feature extractors as front-ends, we show that end-to-end multi-lingual training of sequence models is effective on context independent models trained using Connectionist Temporal Classification (CTC) loss. We show that our model improves performance on Babel languages by over 6% absolute in terms of word/phoneme error rate when compared to mono-lingual systems built in the same setting for these languages. We also show that the trained model can be adapted cross-lingually to an unseen language using just 25% of the target data. We show that training on multiple languages is important for very low resource cross-lingual target scenarios, but not for multi-lingual testing scenarios. Here, it appears beneficial to include large well prepared datasets.
