Eleven Voices, One Message: Regionalized AI Radio Spots for the New EWE DSL Tariffs

Background and Challenge

EWE TEL and osnatel faced the task of promoting their DSL products strategically across different regions. This required an authentic Northern German tone that would both activate existing customers and attract new ones. The particular challenge lay in the large number of regional variants needed while production resources remained limited – traditional studio recording would have exceeded budgets and severely restricted flexibility.

Approach and Realization

The solution was an innovative, scalable approach: We first developed a radio pilot spot as a blueprint for the entire campaign. Using Wondercraft, we deployed AI voice technology that generated individual voices with regional accents. With CapCut, we handled the professional editing and final processing of the audio files. This resulted in eleven regionally adapted spot variants. In areas with fiber optic infrastructure, we adjusted the product focus accordingly and specifically promoted fiber connections. The AI-powered production enabled rapid, flexible implementation completely independent of studio availability while achieving highly personalized audience targeting.

Results

The campaign succeeded with an attention-grabbing radio spot that created clear regional recognition. Each target region received individually tailored messages, made even more precise through product-based differentiation. The AI-supported production delivered significant time and resource savings while establishing a scalable model for future regional audio campaigns. EWE TEL and osnatel benefited from positive responses to the authentic regional connection and targeted approach to their audiences.
