Always love the reviews but I rarely comment, and just don't take the time to read all responses... so, don't know if this has been addressed.

Page is using a talk box, not a vocoder. A vocoder can be a pretty complicated device. Talk box... not so much. A talk box can give a similar result in sound as a vocoder, but it's still a very different kind of tool. Google them to learn more or ask your favorite music tech geek.

And thanks for the review!
