摘要翻译：
序列到序列模型为构建语音识别系统提供了一个简单而优雅的解决方案，它将典型系统的独立组件，即声学(AM)、发音(PM)和语言(LM)模型折叠到单个神经网络中。在这项工作中，我们研究了一个这样的序列到序列模型，即听、出席和拼写(LAS)，并探索了训练一个单一模型来服务于不同英语方言的可能性，该模型简化了多方言系统的训练过程，而不需要为每个方言单独提供AM、PM和LMs。我们表明，简单地将所有方言的数据汇集到一个LAS模型中，落后于对每个方言进行微调的模型的性能。然后，我们考虑将方言特有的信息纳入模型，通过在原始字素序列的末尾插入方言符号来修改训练目标，以及将方言信息的1-热表示添加到模型的所有层。对7种英语方言的实验结果表明，我们提出的系统在单个LAS模型中对方言变化的建模是有效的，相对于单独训练的LAS模型在7种方言上的性能提高了3.1～16.5%。

英文摘要：
  Sequence-to-sequence models provide a simple and elegant solution for building speech recognition systems by folding separate components of a typical system, namely acoustic (AM), pronunciation (PM) and language (LM) models into a single neural network. In this work, we look at one such sequence-to-sequence model, namely listen, attend and spell (LAS), and explore the possibility of training a single model to serve different English dialects, which simplifies the process of training multi-dialect systems without the need for separate AM, PM and LMs for each dialect. We show that simply pooling the data from all dialects into one LAS model falls behind the performance of a model fine-tuned on each dialect. We then look at incorporating dialect-specific information into the model, both by modifying the training targets by inserting the dialect symbol at the end of the original grapheme sequence and also feeding a 1-hot representation of the dialect information into all layers of the model. Experimental results on seven English dialects show that our proposed system is effective in modeling dialect variations within a single LAS model, outperforming a LAS model trained individually on each of the seven dialects by 3.1 ~ 16.5% relative.
