Commercials regularly feature foreign accents. This paper aims to investigate whether the use of foreign accents in radio commercials is more effective for congruent than incongruent products, and whether foreign-accented commercials are evaluated differently than non-accented commercials. In an experiment, a group of 228 Dutch participants rated non-accented and accented commercials for four different products in a between-subject design. The products were either congruent or incongruent with the foreign accent in the commercial (e.g. a German-accented commercial for sausage vs. olive oil). Foreign-accented commercials for congruent products were assessed more positively on a number of variables than foreign-accented commercials for incongruent products. Foreign-accented commercials were rated more negatively than commercials without a foreign accent.
