The benefits of AsTeR , which is based on AFL, cannot be
experienced by reading a printed document such as this; rather, one
has to listen to AsTeR in action. Suffice it to say that
AsTeR has made it possible for the author to read current technical
material, on his own, that otherwise would not have been available for
years (if at all). Further, he can tune the renderings
(see c:rules_and_styles) to his liking and can even browse the
document. Thus, AFL represents a gigantic step forward in providing
the tools necessary to render technical documents in audio.
Several further points can be made.
- AFL provides for audio renderings the same power that TeX
provides for visual renderings. AFL has made it possible for us to
experiment easily and quickly with different audio renderings of
mathematical notations. In this regard, we are limited only by our
own ability to think of new ways of rendering mathematics clearly
and succinctly; the language itself is not the limitation.
- As a result of its focus on multiple components,
AFL is an extensible tool for writing high-level programs for
producing multimodal renderings of information.
While it is not trivial to design and implement a new audio component,
it also need not be a long and
laborious affair. Based on the author's experience, we guess that
it would take him less than a week to add a new component that is based on
a different speech synthesizer or sound component.
