I've heard people say:
Dee'aw for Dior, which the French pronounce D'yor, one syllable
Fay'leeceetay Perpetch'way for Félicité Perpétue, pronounced Fe'licitay Per'petoo (a rose variety)
Mrs Chollymon'dowlay for Mrs Cholmondeley, pronounced Chum'ley (a clematis variety, but a forgivable mistake unless you are my irritating Esstay Lawday-wearing exMIL)
Far'zate for Phase Eight, and last but not least, I give you
Fokes'wahrgon for Volkswagen (yes, once again my not-to-be-outdone exMIL, bless her)
