IEC 62665:2015(E)本国际标准规定: -用于生成纹理图的文本编码方案， -用于打印的纹理图的物理形状和尺寸， -纹理贴图打印的附加功能和 -纹理图解码和解码文本的听觉呈现。这些规范使视障人士和非视障人士之间能够交换文件和出版物。第二版取消并取代了2012年出版的第一版，构成技术修订。与上一版相比，该版本包括以下重大技术变化。两种不同的控制码由不同的术语描述:“用于文本的控制码”和“用于语音的控制码”。Pack处理和LZSS处理在它们的附加子条款中示出。添加了头文件“Speechio.h”的示例。在附加附录D中示出了纠错编码的示例。

IEC 62665:2015(E) this International Standard specifies:
- a text encoding scheme to generate a texture map,
- a physical shape and dimension of the texture map for printing,
- additional features for texture map printing and
- a texture map decoding and an auditory presentation of decoded texts. These specifications enable the interchange of documents and publications between visually impaired and non-impaired people. This second edition cancels and replaces the first edition published in 2012 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition. Two different control codes are described by the different terms: "control codes for text" and "control codes for speech". Pack processing and LZSS processing are shown in their additional subclauses. An example of the header file "Speechio.h" is added. An example of error correction encoding is shown in additional Annex D.
