I'm afraid G3ronimo is right. There is no automated way to extract vocals from a song once they've been mixed into a stereo track. You could try a couple of tricks though (however, none of them guaranteed):

1. If you have the exact same song without vocals, you could mix them together so that they cancel each other out except for the vocals. You'd have to invert one of the songs (phase shift 180). Of course, if the song contains passages that are exactly the same except one has vocals and the other doesn't, then you could try the same there by doing some cut'n'paste. In theory this should work, but you'd probably end up with some artifacts in the vocals anyway.

2. In Adobe Audition there is an effect called "Center channel extractor". Since vocals are often left in the center (while instruments are panned out into the stereo field), you could perhaps get a satisfactory result processing the file with this effect (or a similar one). In combination with a stereo expander (which pushes sounds that are panned even a bit left or right even further left or right) it might be possible to get something worthwile out of the vocals.

3. Most vocals fall into the range of 100-2.5kHz (roughly speaking). Using an EQ you could remove everything outside this range and be left with only the sounds that fall into the same range as the voice. By itself this probably won't do enough, but in combination with 2. it might do the trick.

As with most things music, experimenting really is the only way to go here. Try different settings and see when it gets better. Personally, I'd start with the center channel extractor and stereo expanding to see what I'm left with. I'd try both expanding then extracting the center, and only extracting the center. After that I'd try using a multiband compressor to see if I can't raise the vocals over the other noise. Then I'd start EQ:ing to see if I can cut away more stuff that isn't needed. Adobe Audition has some fine noise reduction tools that I'd try also.

In the end though, you'll have a tough time getting a quality result.
