I report on studies of inclusive and exclusive semileptonic b -> c l nu and b -> u l nu decays in 9.7 million BBbar events accumulated with the CLEO detector in symmetric e^+e^- collisions produced in the Cornell Electron Storage Ring (CESR). Various experimental techniques, including the study of spectral moments and the inference of neutrino candidates by exploiting the hermeticity of the CLEO detector, are used in conjunction with theoretical calculations to provide estimates of the CKM matrix elements |Vcb| and |Vub|.
