摘要翻译：
建模单元的选择是自动语音识别(ASR)任务的关键。传统的ASR系统通常选择上下文相关状态（CD状态）或上下文相关音素（CD音素）作为建模单元。然而，它受到了序列到序列的基于注意力的模型的挑战，这些模型将声学、发音和语言模型集成到一个单一的神经网络中。在英语ASR任务中，以往的尝试已经表明，基于顺序对顺序的注意模型，字形的建模单位优于音素的建模单位。在本文中，我们使用基于注意的序列到序列模型，利用Transformer对汉语ASR任务中的单元进行建模。研究了五个建模单元，包括与语境无关的音素、音节、词、子词和字符。在科大数据集上的实验表明，无词库建模单元在字符错误率(CER)方面优于与词库相关的建模单元。在五个建模单元中，基于字符的模型表现最好，在没有手工设计的词典和额外的语言模型集成的情况下，在科大数据集上建立了一个新的最先进的CER$26.64%$的CER，相对于现有的最先进的CER$28.0%$的CER$4.8%$的相对改进，而基于CTC-注意力的联合编码器-解码器网络的CER$28.0%$。

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：
  The choice of modeling units is critical to automatic speech recognition (ASR) tasks. Conventional ASR systems typically choose context-dependent states (CD-states) or context-dependent phonemes (CD-phonemes) as their modeling units. However, it has been challenged by sequence-to-sequence attention-based models, which integrate an acoustic, pronunciation and language model into a single neural network. On English ASR tasks, previous attempts have already shown that the modeling unit of graphemes can outperform that of phonemes by sequence-to-sequence attention-based model.   In this paper, we are concerned with modeling units on Mandarin Chinese ASR tasks using sequence-to-sequence attention-based models with the Transformer. Five modeling units are explored including context-independent phonemes (CI-phonemes), syllables, words, sub-words and characters. Experiments on HKUST datasets demonstrate that the lexicon free modeling units can outperform lexicon related modeling units in terms of character error rate (CER). Among five modeling units, character based model performs best and establishes a new state-of-the-art CER of $26.64\%$ on HKUST datasets without a hand-designed lexicon and an extra language model integration, which corresponds to a $4.8\%$ relative improvement over the existing best CER of $28.0\%$ by the joint CTC-attention based encoder-decoder network.
