摘要翻译：
在机器唇读中，关于用于识别的正确类别的争论和研究仍在继续。在本文中，我们使用一种结构化的方法来设计说话人相关的视素类，这种方法能够创建一组音素到视素的映射，其中每个视素都有不同数量的视素，从2到45不等。Viseme类是基于在音素识别过程中被混淆的拼接音素映射到Viseme组。利用这些映射，结合LiLIR数据集，我们展示了在说话人相关的机器唇读中改变viseme映射大小的效果，并用单词识别的正确性来衡量，从而证明用音素分类器进行单词识别不仅是可能的，而且往往比用viseme分类器进行单词识别更好。此外，在音素和音素之间有中间单位，这是更好的。

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：
In machine lip-reading there is continued debate and research around the correct classes to be used for recognition. In this paper we use a structured approach for devising speaker-dependent viseme classes, which enables the creation of a set of phoneme-to-viseme maps where each has a different quantity of visemes ranging from two to 45. Viseme classes are based upon the mapping of articulated phonemes, which have been confused during phoneme recognition, into viseme groups. Using these maps, with the LiLIR dataset, we show the effect of changing the viseme map size in speaker-dependent machine lip-reading, measured by word recognition correctness and so demonstrate that word recognition with phoneme classifiers is not just possible, but often better than word recognition with viseme classifiers. Furthermore, there are intermediate units between visemes and phonemes which are better still.
