We have computed the radiative corrections to the ..beta.. energy spectrum in the semileptonic decay of charged hyperons. Strong-interaction and intermediate-vector-boson effects on the electromagnetic corrections are retained in general by extending an approach that Sirlin introduced for neutron decay. Our result is quite accurate. It is valid up to corrections no larger than a few tenths of a percent. It is suitable for performing experimental analysis in a model-independent fashion.
