simple definition.
I don't see the definition as simple; it is short, but not simple.
Apparently, <acronym> could not mean just "the word is spoken". We are
not supposed to use it for any word, are we? Instead, the implied idea
is probably that <acronym> indicates that the word has originally been
formed as an abbreviation (of initial letters of words). The question
is: why would it be relevant to indicate such a thing in markup?
In almost all cases, it would be distracting if a screen reader spoke
the "expansion" of an acronym. Being an acronym means that the
expression is now a word.
"Abbreviation" is a broad and vague concept, and an abbreviation may be
spoken in different ways: letter by letter, or by pronouncing the
unabbreviated word(s), or as a word (as an acronym). Sometimes even by
pronouncing something completely different, as in reading "e.g." as "for
example".
An issue though, (automatic) translation. for example
<abbr title="United Nations"
lang="en">UN</abbr>
would have to become in French once translated.
<acronym title="Organization des Nations Unies"
lang="fr">ONU</acronym>
And what about e.g. CEN, which might be treated as an acronym, or spoken
using the names of letters (or, in extravagant situations, using the
words from which the abbreviation was once formed)?
<acronym> is unnecessary and confusing. Even <abbr> is problematic,
since it has often been interpreted so that the title="..." attribute
should be read in its stead - even though the attribute was introduced
into HTML as an advisory title, not as a pronunciation instruction.
The issue of telling the suggested spoken form of some written text
should be kept separate from any existing markup features. I know that
some software reads title="..." attributes, but it's normally just an
option, and it conflicts with other uses of the attribute. Authors may
wish to use title="..." just to show a visible tooltip, and they do that
a lot.
