The first is a SIRI like assistant available from Cydia. It's called E.S.R.A.
Second is SIRI but I have never tried this so I don't know how well this will work. Use at your own risk.
This one is also available from Cydia.
NOTE: If you are having trouble with finding anything in Cydia it because you may not have the correct sources (repo) added. Hit me up for more info.
