Although I have been largely responsible to raising this issue, my time is mostly occupied with work on HTML. Perhaps its worth my summarising the points I am aware of: The need is for a way to encode phonemic and prosodic information for irregular words and phrases that are unlikely to appear in dictionaries, e.g. people's names. I envisage dictionaries for different languages, being selected upon the basis of the the HTML Cougar LANG attribute which uses RFC 1766. The encoding should be easy enough for people to make a reasonable job of their own names without needing to be experts in digital speech. This suggests the use of ASCII encodings based up on letter sequences that suggest the intended pronunciation. Note that this introduces cultural biases, so that we may need to think about multiple "input" syntaxes, and a common back-end syntax as is being developed by the W3C HTML-Math working group. The encoding should however be capable in expert hands of more faithful/subtle behaviour. In addition, it shouldn't adversely effect the ability to run speech synthesisers fast, since people are used to doing this to scan texts quickly. The advent of software based speech synthesisers will largely obviate some of the difficulties with today's hardware-based systems. This gives us greater freedom to choose the kinds of features we want, without the constraints imposed by a policy of lowest common denominator for different hardware-based implementations.
