摘要翻译：
在自动语音识别(ASR)中，用户所说的话取决于她所处的特定环境。通常，这个上下文表示为一组单词n-图。在这项工作中，我们提出了一个新的，全神经，端到端(E2E)ASR系统利用这样的上下文。我们的方法，我们重新命名为上下文监听、旁听和拼写(CLAS)，联合优化了ASR组件以及上下文N-图的嵌入。在推理过程中，CLAS系统可以呈现上下文短语，其中可能包含在训练过程中看不到的词汇表外(OOV)术语。我们将我们所提出的系统与一种更传统的上下文化方法进行了比较，该方法在波束搜索过程中对内部训练的LAS和上下文n-gram模型进行了浅融合。在许多任务中，我们发现提出的CLAS系统比基线方法的相对WER多达68%，表明联合优化优于单独训练的组件。索引术语：语音识别，序列到序列模型，听，参加和拼写，LAS，注意，嵌入式语音识别。

英文摘要：
  In automatic speech recognition (ASR) what a user says depends on the particular context she is in. Typically, this context is represented as a set of word n-grams. In this work, we present a novel, all-neural, end-to-end (E2E) ASR sys- tem that utilizes such context. Our approach, which we re- fer to as Contextual Listen, Attend and Spell (CLAS) jointly- optimizes the ASR components along with embeddings of the context n-grams. During inference, the CLAS system can be presented with context phrases which might contain out-of- vocabulary (OOV) terms not seen during training. We com- pare our proposed system to a more traditional contextualiza- tion approach, which performs shallow-fusion between inde- pendently trained LAS and contextual n-gram models during beam search. Across a number of tasks, we find that the pro- posed CLAS system outperforms the baseline method by as much as 68% relative WER, indicating the advantage of joint optimization over individually trained components. Index Terms: speech recognition, sequence-to-sequence models, listen attend and spell, LAS, attention, embedded speech recognition.
