Assistive listening devices and systems for active assisted living - Part 1: General
SIST EN IEC 63087-1:2022

This part of IEC 63087 specifies requirements, and the associated methods of measurement, for the electroacoustic performance of personal listening systems. This document specifies requirements for the provision of assistive listening in audio, video and multimedia systems and equipment. The requirements are of different kinds, because of the diversity of the hardware concerned. Existing IEC standards for methods of measurement are normatively referenced if they exist. Methods of measurement and performance requirements are specified in IEC 63087-21. This document does not apply to hearing aids. Also excluded are devices entirely worn on or in the ear, which cannot be measured independently.

Text-to-speech for television - General requirements
SIST EN IEC 62731:2018

IEC 62731:2018(E) specifies the text-to-speech functionality for a (broadcast) receiver with a text-to-speech system. Such a system may be one device, i.e. a receiver with an integrated text-to-speech generator, or may be two devices, i.e. a receiver interfacing with an external text-to-speech device. This document applies only to completely functional stationary (or semi-stationary) digital TV receivers such as set top boxes, integrated digital TVs, recorders and other products whose primary function is to receive TV content. Where this document refers to TV, this will be shorthand for all such receivers. This document does not apply to products that are capable of receiving TV as a secondary function (e.g. PCs or game consoles with digital television receivers). It also does not apply to sub-assemblies (e.g. PC tuner cards). This edition includes the following significant technical changes with respect to the previous edition: a) in 6.2, the levels of announcement quality were revised as well as considerations for ways in which device users can provide service providers with feedback on incorrectly announced terms. b) in 6.3, the following TV functionality was added: the TV can receive updated words, associated conversions and updated conversion rules for the TTS engine via a network connection.

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.
