Yes, although now they seem to be taking a more psychological approach with exceptance to let it work itself out but there are so many techniques that I am sure they speak of those techniques thus starting the cycle they need them on this or that like it may never just come out otherwise when I think acceptance may lead it to become like any other word over time.  No unique technique among sounds imo, just better to have a one size fits all one or 2 fallback...I did it all my life from my college years and on and entirely reshaped my stutter and my relationship to it.
