Abstract: We extend previous computations of the second order QCD corrections tosemileptonic b \to c inclusive transitions, to the case where the chargedlepton in the final state is massive. This allows accurate description of b \toc \tau \bar u \tau decays. We review techniques used in the computation ofO\alpha s^2 corrections to inclusive semileptonic b \to c transitions andpresent extensive numerical studies of O\alpha s^2 QCD corrections to b \to cl \bar u l decays, for l =e, \tau.
