I personally don't think it's that important, there are less and less
reasons to use consoles at all today (except special cases like booting,
some breakdown situations, etc.). Just when one needs to use console,
it's important to be able to get the speech output some way. But this
should be manageable using the methods similar to what you've outlined.

Not necessarily. It can probably be solved by starting new Speech
Dispatcher (user specific) instance right after new PulseAudio instance
is started. By first testing it seems such a setup works. I just
needed to know whether this is the right/recommended way of doing

Such a feature might be useful, but it's probably not very important for
Thank you for answer and clarification.
