The W3C the Timed Text (TT) Working Group has posted the first public working draft of Timed Text (TT) Authoring Format 1.0 – Distribution Format Exchange Profile (DFXP). According to the abstract,
This document specifies the distribution format exchange profile (DFXP) of the timed text authoring format (TT AF) in terms of a vocabulary and semantics thereof.
The timed text authoring format is a content type that represents timed text media for the purpose of interchange among authoring systems. Timed text is textual information that is intrinsically or extrinsically associated with timing information.
The distribution format exchange profile is intended to be used for the purpose of transcoding or exchanging timed text information among legacy distribution content formats presently in use for subtitling and captioning functions.
The W3C Voice Browser working group has posted Pronunciation Lexicon Specification (PLS) Version 1.0 Requirements. According to the abstrat, "This document is part of a set of requirements studies for voice browsers, and provides details of the requirements for markup used for specifying application specific pronunciation lexicons. Application specific pronunciation lexicons are required in many situations where the default lexicon supplied with a speech recognition or speech synthesis processor does not cover the vocabulary of the application. A pronunciation lexicon is a collection of words or phrases together with their pronunciations specified using an appropriate pronunciation alphabet."
