We consider some extensions of the relation which has been obtained by Nambu and Luri\'e between an elastic process and the accompanying soft pion emission process under the assumption of approximate γ₅ invariance. In particular, a generalized formula is found which enables one to describe the electropion production e+N→N+e+π and the neutrino-pion production ν+N→N+e+π at the threshold of Nπ system in terms of the vector (Hofstadter) and the axial-vector form factors. Explicit forms of the cross sections are given.
