Wheatly talk...
How To Make Wheatley Talk?
Logic_choreographed_scene with prop_dynamic animations. you're new to hammer aren't you?
Actually im also pretty new, right now trying to find the tutorial making the screen with wheatley talking. I remember i've seen the video on youtube, but now i have to find it again.
Actually, it's very easy
1) create a room not too big not too small, about 500-600 units big.
(note: the room needs to be away from the main room.)
2) then create a prop_dynamic with a Wheatley model, look it up in the green browser (make sure that it's only his head and and part of glados' body, not the whole glades' body)
3) create a logic choreographed scene, now you have options, you have the choice of using a vcd or a wav
Vcd: vcds are Scripts, like when your acting in a play they have lines, valve made these so they can organize sounds easier
Wav: wav files are the sound, they can be customized to have any types of sound, like you can have Wheatley and cave at the same time, vcds can not, to browse and listen to sounds go here: http://theportalwiki.com/wiki/Wheatley_voice_lines
Choose one to use.
4) then make a point_camera in front of Wheatley. Then make a brush with the texture dev/monitor for where you want your Wheatley monitor to be.
Tie it to a func_monitor.
Go into the func_monitor's properties and
Set camera name to your point_camera.
5)Then make a trigger, with the following outputs,
OnTrigger - func_monitor - Enable
OnTrigger - point_camera - SetOn
There, hope this helps.
There are instances for this.

I don't need a model of Wheatley, only voice
I tried to create func_instance with 'instances/choreo/glados_gen_actor.vmf', logic_choreographed_scene with 'scenesnpcsphere03bw_a4_finale01_smash02.vcd', and trigger with output 'OnTrigger, chor1, Start' but it doesn't work
It works only if 'Scene file' value is 'scenesnpcglados...'
Technically you just need a wav file with a logic choreographed scene, if you don't need a Wheatley monitor. Just make a logic choreograpghed scene with the wav file and make a trigger to play its wav
Hi. In my newest map i only used ambient_generic to make him talk 
you can go into your portal 2/portal2 folder and i Think its in "recourses" where you Can find All the Lines and their in-hammer-name.
If you need to make the monitor for wheatley go to instances>monitors and select:
wheatley big screen
Wheatley studio
Place studio outside the map and call it: studio
Place the screen inside the map where you want it and call it: screen
Make a trigger_once with the outputs:
On trigger-screen-(something with deploy)
On trigger-screen-(something with enable)
On trigger-studio-(1 of the 4 options you want)
You can also let the ambient_generic get triggered by the trigger_once. Thats what i do. Remember to flag:
is NOT looped
Play everywhere
And unflag:
Start silent
I guess thats it. Happy experiment ^^
