Texture map for auditory presentation of printed texts

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.
