Nonperturbative corrections up to [ital m][sub [ital b]][sup [minus]2] to the heavy lepton energy distributions are investigated in the inclusive semileptonic weak decays of heavy flavors in QCD. In the case of [ital B]-meson decays, for [ital b][r arrow][ital u][tau][bar [nu]] transitions they decrease the decay rate by 6% of its perturbative value, while for [ital b][r arrow][ital c][tau][bar [nu]] they decrease it by 10%.
