摘要翻译：
纯视觉语音识别依赖于许多难以控制的因素，例如：照明；身份；动议；情感和表达。但有些因素，如视频分辨率是可控的，因此目前还没有系统的研究分辨率对唇读的影响。在这里，我们使用一个新的数据集Rosetta Raven数据来训练和测试识别器，从而测量视频分辨率对识别精度的影响。我们的结论是，与通常的做法相反，自动唇读的分辨率不需要那么高。然而，当下唇底部和上唇顶部之间的距离在静止状态下小于四个像素时，自动唇读不太可能可靠地工作。

英文摘要：
  Visual-only speech recognition is dependent upon a number of factors that can be difficult to control, such as: lighting; identity; motion; emotion and expression. But some factors, such as video resolution are controllable, so it is surprising that there is not yet a systematic study of the effect of resolution on lip-reading. Here we use a new data set, the Rosetta Raven data, to train and test recognizers so we can measure the affect of video resolution on recognition accuracy. We conclude that, contrary to common practice, resolution need not be that great for automatic lip-reading. However it is highly unlikely that automatic lip-reading can work reliably when the distance between the bottom of the lower lip and the top of the upper lip is less than four pixels at rest.
