AudioStack Expands Multi-Model Voice Orchestration, Welcoming Gradium as Latest Roster Partner
by on 24th Aug 2026 in News

AudioStack, the agentic audio production platform for media and advertising, announced Gradium has been added to its roster of voice providers. The addition reflects AudioStack's ongoing investment in providing the largest and most complementary selection of voices, languages, and accents, orchestrating every major voice, music, and sound provider on one platform, so brands, agencies, publishers, and platforms always have the right voice for the job, whatever the brief, to produce audio at scale across markets.
"Content and ad creative performance is directly correlated to the quality and the relevance of the media being produced," said Alexis van de Wyer, CEO at AudioStack. "To ensure our agentic platform delivers such quality and contextual relevance, we’re deliberate about who we bring onto the platform. Gradium's depth of offering meets that bar, and that's exactly the kind of partner we want as we keep expanding the network powering our customers' audio production."
"We were impressed by Gradium's range and consistency, offering high-quality regional accents, such as Australian, alongside French-language depth that includes French Canadian voices, which have already helped AudioStack support customers in that market. Finding the best partners globally, with the regional expertise to back it up, has been a key priority as we grow the breadth of models available on the platform." Alexis added.
For Gradium, the partnership opens a new channel into AudioStack's agentic production tools and the customers building on them.
"We're proud to bring Gradium's voice models into a platform where craft and scale come together. AudioStack customers can now pull voices with native regional depth straight into their production pipeline, whether the brief calls for Dublin English, Bavarian German, or anything in between. An ad that sounds local performs like one, and that's the gap this closes," said Neil Zeghidour, CEO at Gradium.
Looking ahead, AudioStack said Gradium's addition fits squarely into where the platform is headed next.
"Our vision is to enable and empower any media organisations to produce great-sounding audio at scale," said Alexis van de Wyer. "Gradium fits well into that vision, and we're excited about what we'll build together as we push further into that space."
Gradium's voices are live now on AudioStack in English and French, including French Canadian, with more languages to come.
Welcoming Gradium to the platform, AudioStack said the roster will keep growing in the same direction: continuity, global reach, and partners — across voice, music, and sound — with the regional depth to match.
