More Voices, More Markets: AudioStack Rolls Out ElevenLabs' v4
by on 23rd Oct 2026 in News
AudioStack, the agentic audio production platform for media and advertising, announced it is rolling out support for ElevenLabs' newly launched Eleven v4 and Eleven v4 Turbo models across its platform. The rollout is part of AudioStack's ongoing strategy of orchestrating across every major voice, music, and sound model, so that every brief is automatically matched to whichever model delivers the highest quality for that job.
ElevenLabs' v4 models, announced last month, expand native-language coverage to more than 90 languages, with notable gains in regions including Brazil and Japan, alongside finer-grained control over vocal delivery. AudioStack's agentic production stack, which automates casting, script generation, timing, mixing, and delivery to broadcast spec, will incorporate v4 into its model catalogue on a gradual rollout basis over the coming weeks.
"We're excited to partner with ElevenLabs on the v4 release," said Erik Barraud, chief product officer at AudioStack. "More voices and languages means our orchestration layer has an even stronger set of models to draw on, which lets us expand what we can offer customers and raises the bar for what quality AI audio can sound like across every market we serve."
"We're excited to see partners like AudioStack bring v4 into production workflows quickly," said Angelos Perivolaropoulos, research engineering lead at ElevenLabs. "v4 was built to give creators and businesses alike more expressive and natural voices across more languages than ever. Partnerships like this are exactly how this technology will reach the hands of people scaling real campaigns in markets and industries around the world."
This reflects how AudioStack approaches model partnerships more broadly. By orchestrating across every major voice, music, and sound model, the platform routes each brief to the model that best serves the brand, region, and creative brief at hand. As ElevenLabs continues to evolve its voices and expand into new languages and markets, that standard keeps rising, giving AudioStack's production agents an even stronger set of voices to cast from.
The move reflects AudioStack's broader strategy of expanding the languages, models, and markets its platform can serve at broadcast quality, as demand grows for audio production at scale across advertising, publishing, and real-time voice agent use cases. Customers already using AudioStack's agentic platform, including Azerion and Publicis Groupe, will gain access to v4 as part of this rollout, with no changes required to their existing workflows.
