We assess the reactions of Generation Z consumers to hard and soft sell vocal styles in two countries (France and New Zealand) to understand whether the association of warmth and competence personality traits differs across countries. Results reveal commonalities and differences that advertisers should take into consideration when designing advertising vocal strategies. In both countries, the soft sell vocal style conveyed significantly more warmth than the hard sell style. Our study also reveals differences between countries with French participants having a clear preference for soft sell voices, which they rated very high in both warmth and competence, whereas participants from New Zealand found the hard sell voices significantly more competent than French participants did.
