Neico pretty much nailed what I was in the process of writing.
At least back in the EP1 code base there was still code to handle the
original HL1 method of moving the player model mouths based on the
amplitude of the input audio. It basically moved a controller bone alone a
defined axis based on the volume making the jaw "flap". It's in the code
base for the HL1:Source port.
I used it myself and got the mouths of HL2 player models to move based on
the in-game voice volume so the code is still "valid".
I'd start looking there at the code that controls the jaw and look at where
to pull the amplitude out (a normalised value).
