   <hidden TTP97-24  |V_cb| from semileptonic B decays with two-loop QCD accuracy  > Recent progress in calculating ${\cal O}(\alpha _s ^2)$ corrections
 to inclusive and exclusive semileptonic $b \to c$ transitions
 is  reviewed. The impact of these corrections on the $|V_{cb}|$\
 determination from both inclusive  and exclusive $B$ decays is
 discussed.
