Simple answer: there is no simple answer. Title attribute on what? If
it's on an element that not focussable via keyboard, I believe
screenreaders won't read it out. Even if it's on a link or similar, it
depends on specific screenreader settings. And for sighted (but possibly
colour blind) users that rely on keyboard navigation, title is never (to
my knowledge) exposed (i.e. no browser generates a tooltip or similar if
the user isn't using a mouse).

It depends on context, but in many cases I'd say that assertion is
false. You'd need to give a specific example here for a more authoritive
answer, I think...
