French to English Art/Literary Journalism

In a cv for someone who's worked a lot in TV and journalism, they say: "Gestion d'une équipe de post-production (réalisateurs post productions, monteurs, chef d'édition, mixeurs, VOICEURS)". No explanation is given for "voiceurs" and they are not mentioned anywhere else in the cv. Are these the actual "voice-over artists" or, more probably, given the other roles listed, could they be the technical people responsible for adding in voice-overs or dubbing at the post-production stage? If so, does anyone know what they are called in English? Internet searches have drawn a blank.
