AudioStack Adds Gradium to Voice Roster
AudioStack, an agentic audio production platform for media and advertising, announced it has added Gradium to its roster of voice providers. The partnership expands AudioStack's multi-model voice orchestration, bringing Gradium's regional and language-specific voice models (English and French, including French Canadian) into AudioStack's production pipeline. AudioStack CEO Alexis van de Wyer and Gradium CEO Neil Zeghidour both commented on the strategic fit: AudioStack seeks partners with regional depth to improve ad creative relevance and scale, while Gradium gains a new channel into AudioStack's agentic production tools and customers. AudioStack said the roster will continue to grow to provide continuity, global reach, and regional voice expertise across voice, music, and sound.
Platform-level partnership expands voice model variety and regional language support for audio ad creative production, aiding advertisers, agencies and publishers that scale audio creative — but it is a vendor-level update rather than a major platform or policy change.
