If by 'reliably', you mean 'override the users choice of having the
speaker on or off', then I think you need a rethink. :)

There are several utilities about that can do the beeping (and music)
for you, and IIRC even ones that work across platforms.

Suggestion: allow a configurable command to be called, so that users
can choose their own notification method, eg. /usr/bin/play (a part of
'sox').
