HazardsMind:
You can maybe look into EasyVR.
I also found this. Would have to order from China, though. Looks like a neat module:

I will check out the EasyVR.
Looking at RTC modules, they all seem to be missing the one most useful feature: an alarm interrupt output. Maybe the newer RTC chips don't have that feature anymore. Hmm... I may have to design my own (not very difficult.)
