Gradium voices are now live on AudioStack

AudioStack, the agentic audio production platform for media and advertising, has added Gradium to its roster of voice providers. Our voices are live on the platform now, across multiple languages and regional accents.

Orchestrating every voice on one platform

AudioStack turns a brief or raw content into broadcast-ready audio at any scale. It automates every step of production: script generation, voice, music, sound design, mixing, and mastering. Agencies, publishers, and platforms use it via API or console to go from one ad to 10,000 variants, or from a 30-second spot to a 30-minute audiobook.

Adding Gradium reflects AudioStack's ongoing investment in the largest and most complementary selection of voices, languages, and accents, orchestrating every major voice, music, and sound provider in one place so its customers always have the right voice for the brief, whatever the market.

"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."

Regional depth was the deciding factor

"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," Alexis added. "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."

For Gradium, the partnership opens a new channel into AudioStack's agentic production tools and the customers building on them.

"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.

Where this goes next

"Our vision is to enable and empower any media organizations 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."

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.
