AudioStack Adds Inworld to its Voice Roster

AudioStack, the agentic audio production platform for media and advertising, today announced Inworld as its newest voice partner, bringing the platform's total roster of voice, music, and sound providers to nineteen. The addition gives customers a wider set of regional and demographic options to draw on from within a single, model-agnostic platform.

“Inworld is exactly the kind of partner that makes this platform better, not just bigger. Strong regional coverage, real range across ages — that's the kind of depth we're building toward,” said Erik Barraud, CPO at AudioStack.

“What stood out with Inworld was the UK accent coverage, paired with a genuinely wide age range across their voices, which gives customers a lot more precision when a brief calls for a specific kind of person, not just a specific kind of sound. That precision matters because voice is personal — the right accent and age in context is often what makes a listener feel like a creative is actually speaking to them, not just at them. That's the kind of connection we want every customer to be able to build.”

This is one of the quieter benefits of building with AudioStack: the platform keeps expanding, but nothing changes for customers. There's no new contract to sign, no separate integration to build, and no additional setup required when a new partner joins the roster. Customers get more to work with — never more to manage.

The partnership gives Inworld a direct route into AudioStack's customer base and its agentic production tools.

“Being added as a Voice AI provider puts Inworld voices right where the work happens, and we're glad to be part of it,” said Kylan Gibbs, CEO at Inworld.

Inworld's voices are live now on the AudioStack platform. AudioStack said the roster will keep expanding on the same basis — depth and quality over headline count, with regional and demographic range to match, and zero extra work for customers along the way.
