HCS requires a registered voiceattack just as a fyi.
I bought HCS Eli coz I thought it might be fun to have a cranky ship computer. But I rarely use it. Not because it's bad but because of voiceattack....Nothing voice controlled works well for me. I must have a difficult accent or my mic is crap (though that wouldn't apply to my car and my phone and my android tv and...). The end result is frustation.
I also didn't realise that Eli does not come with the background info (stories of the nebula and such) so quite possibly I'd be better of with verity/astra.
EDDI works well but I found it too verbose after a while (was a good 8 months ago so maybe it changed since). EDD is a nice balance and easy to customise (I turn off the edsm announcements else it rabbits on forever each jump).
I recall someone doing a voice for the npc interactions but I forget where I saw that.....will come back.
Edit... Found it;
