Welcome to VSI São Paulo: Vox Mundi

A history of excellence

With over twenty years of industry experience, we have a long history of providing localisation services in Portuguese for one of the world’s key dubbing territories – Brazil.

Acquired by the VSI Group in 2021, after years of collaboration as a trusted partner, VSI Vox Mundi has brought a wealth of knowledge and experience in serving this major Latin American market. Based in São Paulo, we have a global yet local approach, that has won the confidence of clients throughout the entertainment industry, in streaming and broadcast TV, theatrical production and distribution.

Known for our high quality, large capacity and exceptional client service, we offer a variety of localisation solutions, including sound design, mixing, subtitling and access services, but our core strengths lie in expert lip-sync dubbing and voice-over.

Our teams’ tireless work ethic and innovative problem-solving skills are complemented by their knowledge and understanding of the industry and the vibrant but often challenging LatAm market. This is what makes us unique to our clients, with whom we’ve maintained long-standing relationships over the years based on our commitment to delivering quality.

As one of the largest Brazilian dubbing operations, with 14 recording/mixing rooms, you can trust us to get the job done.

Our services


Exceptional dubbing goes unnoticed. It’s an art. An exercise in precision. A creative and technical challenge that can make or break a project in any market. And it’s a challenge we relish.


The best translations sound authentic – as if they were first written in that language. The secret is a deep appreciation for local culture. And we know how far that can take you.

Audio Post-Production

Seeing isn’t the only way of believing: great sound can move people in ways that no other format can match. It’s an art that we've been perfecting for over 33 years.


Telling a story in a new language is a difficult task, especially if it’s in the form of subtitles. There’s a lot to consider: accuracy, timing, relevance and emotion. For us, it’s business as usual.

Access Services

We don’t all experience entertainment the same way: over 2 billion people are hearing or visually impaired. We make every moment meaningful – for everyone.

Our extensive facility in São Paulo, covering 1000 square metres, houses 8 recording and 6 mixing rooms, as well as several HD edit suites, making it one of the largest and best-known studios in Brazil.
