Bigmouth is an audio production studio based in Glasgow and London, working with storytellers across the world - from indie developers to AAA studios, animation producers, and content creators.

Founded with a deep love for character, story, and sound, we’ve grown from a small team of specialists into a trusted partner for games, animation, advertising, and branded content.

Whether we’re casting voices, directing performances, designing sound, or mixing for final delivery, our mission is simple - to help creators tell unforgettable stories through sound that moves, connects, and resonates.

We’re proudly independent, quietly ambitious, and always driven by one thing: the story.
