Looking for a vocal effect

[Thyrai]

Hey guys, I'll probably end up kicking myself at how easy this probably is; but I'm having a bit of a time replicating a certain vocal effect. My best guess is some sort of chorus/layering technique, but here's what it sounds like.

At about 3:41


At about the 2:48 Mark


Thanks!

a vocoder/ a bitspeek effect put on low depth would do it.
