Granted, however, <acronym> is closer to <abbr> than <span> is.  While
semanticly different, I venture to guess most people have a hard time
explaining the difference.

Again, in principle there is no disagreement, however in the context of the
original question the comment/question specifically related to the
appearance of the tool tip, which *can* add accessibility to users with
cognitive disabilities by visually defining (every time) the meaning of the
abbreviated text (or acronym as the case may be), as well as making the
definition available to speech technology if required.  And by cognitive
disability I am not just referring to those with severe limitations;  I deal
with numerous Canadian Federal instituions which regularly use acroymns in
every day speech - they make total sense to civil servants but mean
virtually nothing to those outside of government.  Agencies in particular:
CCRA, PWGSC, TBS... do these mean anything to you? ("Canada Customs and
Revenue Agency", "Public Works and Governments Services Canada", "Treasury
Board Secritariat" respectively).  The "tool tip" would aid non governmental
users by "explaining" terms or acronyms to the non-initiated - improving
accessibility.

Exactly my point.  This word in particular can be both an acroymn and an
abbreviation according to the *common* interpretation of the two terms.  Now
play it out against the current crop of user agents and ask, which of the
two tag elements is better supported today?  And do the average end users
really know or care about the semantic differences between abbreviation and
acronym?

As for the question you pose:

  <acronym title="United Nations International Children's Emergency Fund"
style="speak: normal;">UNICEF</acronym>
  <acronym title="Hyper Text Markup Language" style="speak:
spell-out;">HTML</acronym>

After all, if the speach browser *really* is doing what the standards
expect, then this too should work <grin>.

Excellant advice and again, no argument here.

Cheers.
