Bose-Einstein correlations of pions are calculated in the presence of both statistical and coherent pion production. An isotopic spin conservation is taken into account for the coherent component. Additional contributions due to the isospin effect in pion correlation functions are found. Moreover, the experimental data of two-particle Bose-Einstein correlations for neutral pions are analyzed in this scheme.
