When we launched Adthos, we set out to give creators, advertisers, and broadcasters access to the best possible voice for every piece of content they produce. Today, that mission hits a new milestone: the Adthos voice library has grown to over 22,000 voices, making it the largest AI voice library in the world. That’s not just a number. It’s 22,000 options for finding the voice that sounds exactly right for your brand, your audience, and your content.

The road to 22k: how we got here

The Adthos voice library isn’t built from a single source. We’ve integrated with the leading voice technology platforms in the industry — ElevenLabs, Google, and Microsoft — and combined their catalogues into one unified, searchable library. The result is an unmatched range of vocal styles, accents, tones, and languages, all accessible from a single platform. With support for 200+ languages and dialects, Adthos is built for global content production. Whether you’re producing a localised ad campaign, a multilingual podcast, or a news broadcast for international audiences, the right voice is in the library.

What does this mean for you?

Voice is one of the most powerful elements in audio content. The wrong one can undermine even the best script. The right one builds trust, sets tone, and connects with listeners in a way that sticks. For podcasters, that means finding a voice that fits the personality of your show. For advertisers, it means testing and optimising for audience response at scale. For broadcasters, it means maintaining consistency across segments without being tied to a single talent.

With 22,000 voices — and growing — Adthos gives you the range to get it right every time.
