摘要翻译：
为了进行机器唇读，我们试图从视觉信号中识别语音。目前的工作经常使用由语言模型支持的viseme分类，并取得了不同程度的成功。最近的一些研究表明，在适当的情况下，音素分类可以优于视素分类。在这项工作中，我们提出了一种新的两遍训练音素分类器的方法，在第一遍使用先前训练过的视素。在新的训练算法下，我们的分类性能比以前的唇读结果有了明显的提高。

英文摘要：
  To undertake machine lip-reading, we try to recognise speech from a visual signal. Current work often uses viseme classification supported by language models with varying degrees of success. A few recent works suggest phoneme classification, in the right circumstances, can outperform viseme classification. In this work we present a novel two-pass method of training phoneme classifiers which uses previously trained visemes in the first pass. With our new training algorithm, we show classification performance which significantly improves on previous lip-reading results.
