This is a neat way to use ReVoxer audio; and we **should**kri wrote: Maybe you could even include a feature for this into ReVoxer itself. This would probably be a feature to be added when the core important stuff is set. For example, you could put something akin to a link in the text where you have the presence of a note. When one clicks on the  or * that marks a note, it would pause the recording and pop up a little text box with the footnote so you can read it.
have a way to handle footnotes in some way, since they
appear in all sorts of books. Thanks for raising the issue.
However I am not convinced whether this could be better
handled by ReVoxer than by html or xml. Orchestrating
nonlinear content, as in the example of footnotes, could
be better handled by standard document markup; however
this remains to be confirmed with evidence (i.e. till we have
a prototype). More importantly there will be all sorts of text
rendering issues that we need to deal with if we make it a
ReVoxer a standalone book reader; people will want rich
content with images, video and other media in their books,
and we will have difficulty in having ReVoxer handle all these
in one package.
My point is, ReVoxer has to be flexible and extensible enough to be
used by other applications (like web pages and xml documents). Once
we achieve such flexibility, we will be able to to harness functionalities
that those applications provide; like footnotes as you said and many
others that we cannot think of or imagine now.
