I was expecting Taxman to post this and perhaps he can elaborate.
Npcs seem to have no problems 'hearing' you when you talk when concealed.
I confirmed the same thing. Using same scripts as 095.
[17:24] taxman: speech events was changed in 096? i cant see this in core-changes but merchants can hear me while i'm concealed
[17:24] OldnGrey: do the merchants have any privileges?
[17:24] taxman: invul
[17:26] OldnGrey: interesting, happens to me too!
[17:29] taxman: I'm still concealed but can buy anything
[17:29] * taxman going to add another IF to prevent this
[17:29] taxman: heh
[17:30] taxman: oops
[17:30] taxman: gambler can see me in conceal
[17:30] taxman: spy
[17:30] taxman: EnableEvents(EVID_ENTEREDAREA + EVID_LEFTAREA, HALT_THRESHOLD);
[17:31] taxman: he got this event
[17:31] taxman: conceal seems broken
[17:34] taxman: was go to gambler in stealth
[17:34] taxman: he can see me too
[17:34] OldnGrey: were you cmdlevel or player>
[17:34] taxman: tester
[17:36] taxman: why npc got EVID_ENTEREDAREA if mobile who coming is invisible for him? Its wrong i think
[17:41] taxman: our scripts was started from 094 distro long time ago and rewrited almost totally
