It's been a whlie since i played the game and made the mod but there should be one input to the side of the others you can input to.
Send it a string input of any of the words on the half-life-vox.com website and it'll play it

What inputs/outputs do I use, there are so many options. I suck at wiring sorry.

The input signals has to be the text you want it to say, and it'll speak any words that are from https://half-life-vox.com/
So e.g. you can wire a wifi receiver set to pick up radio chat to the relay and it'll then respond to stuff you say with your headset

yo whats the commands or do you just put words in??

Hey Luff, glad you like it :3
I don't really know what i'm doing with barotrauma modding, but I think my Content Package thing is wrong and is causing the issue. I had intended for the mod to be in a folder called barotrauma-vox, but i didn't really understand what the XML was doing.
I'm still looking at it and i'll be playing around with trying to fix it proper soon (the folder structure i originally had and the one that exists in the mod when downloaded from the workshop is slightly different).
As for the range of voices - I wrote a script to autogenerate the mod from a collection of audio files, so it should have all of them and if you know of (or wanted to create) a better VOX with more useful words all we need is a folder of ogg files named after their trigger words (e.g. "delta.ogg" to say the word "delta").

For anyone wanting to try the mod out right now, I found the problem, (although i did this three days ago so I might've gotten things mixed up by now). Change the file path to each OGG sound file in Mods\Half-Life VOX\Content\Items: vox.xml to where the sound files actually are. Use the search and replace function in notepad++.

To eeee:
No worries. I also feel like I want to share that I see great potential in an announcing system. I mean, I spent like 6 hours the other day trying to find all the words and sound effects in there. I cross-referenced with videos on the net showing all of the words the VOX could say, and it looks like you've implemented every last one. Just wow..That's amazing work!

I also tried figuring out how this could actually be used on a ship, everything from automated warnings about monsters boarding the ship to having a terminal in the command room that the captain/assistant would type important messages into.

Oops - thanks for the heads up. Quite busy right now but I'll try sort that out when I can.

Hey, I love the concept of this! Found an issue though, if you spawn a vox item, the game tries to pull the corresponding ogg from invalid file paths. (...\Barotrauma\Mods\barotrauma-vox...). "barotrauma-vox does not exist."
The oggs are in "Barotrauma\Mods\Half-Life VOX\Content\Items\Vox"

I love it
