QCD sum rules are used to calculate the couplings of heavy-light quark
pseudoscalar and vector mesons ($D, D^*$ and $B, B^*$) with soft pions, both
for finite and infinitely heavy quark mass. The couplings are also computed in
the framework of a QCD relativistic potential model; in this approach the
relativistic corrections due to the light quark are relevant.
