S Voice is on 188.8.131.52 but it hasn't received an update for a little while now. That is the latest version though.
As for freezing/disabling apps, yes, when an update appears, you get a prompt to download. You have two choices:
1/ Download, install then disable again (until another update comes along and repeat the process)
2/ Uninstall the app via root and don't worry about it again.
