Abstract: This specification describes technologies relating to recognition of text in various media. In general, one aspect of the subject matter described in this specification can be embodied in methods that include receiving an input signal including data representing one or more words and passing the input signal to a text recognition system that generates a recognized text string based on the input signal. The methods may further include receiving the recognized text string from the text recognition system. The methods may further include presenting the recognized text string to a user and receiving a corrected text string based on input from the user. The methods may further include checking if an edit distance between the corrected text string and the recognized text string is below a threshold. If the edit distance is below the threshold, the corrected text string may be passed to the text recognition system for training purposes.

Abstract translation: 本说明书描述了在各种媒体中识别文本的技术。 通常，本说明书中描述的主题的一个方面可以体现在包括接收包括表示一个或多个字的数据的输入信号并将输入信号传递到文本识别系统的方法中，所述文本识别系统基于 输入信号。 所述方法还可以包括从文本识别系统接收所识别的文本串。 所述方法还可以包括将识别的文本串呈现给用户，并且基于来自用户的输入接收经校正的文本串。 所述方法还可以包括检查所述经修正的文本串与所识别的文本串之间的编辑距离是否低于阈值。 如果编辑距离低于阈值，则为了训练目的，校正的文本串可以被传递到文本识别系统。
