Multilingual mark-up of text-audio synchronization at a word-by-word level, how HTML5 may assist in-browser solutions

W3C standards and recommendations can be adopted to facilitate multilingual narration by synchronising the presentation of text and audio sources at a word-by-word level. The advent of HTML5 audio within the browser, in particular, is a key enabler. We explore the issues arising in scripting using that standard to allow people on the web to mark-up audio cue-points that correspond to particular words in the text, leading towards a tool that may be useful in multilingual appreciation/learning. This work extends our existing MLW semantic mark-up prototype first presented at the Pisa MLW Workshop.
