I would like to suggest that espeak either temporarily disabled on taskcoach startup or reminders are queued and triggered one at a time.
Currently if a user like myself has a dozen reminders they are all spoken at once resulting in an unintelligible cacophony of noise and also results in each espeak process becoming a zombie.
This should be fixed in the daily build, see http://www.fraca7.net/TaskCoach-packages/latest_bugfixes.py
You need revision 5671 or newer.
