How Fuzzr built voice-powered advertising workflows with ElevenLabs

Fuzzr, a Brazilian audio production company specializing in advertising content for the retail industry, used ElevenLabs' ElevenAPI platform, including Voice Cloning, to build a production pipeline that generates large volumes of advertising audio without sacrificing voice quality or actor consent. The company's platform supports agencies and brands producing radio commercials, promotional sound-truck campaigns, and digital audio at scale. As demand for personalized advertising audio grew, Fuzzr needed voice infrastructure that could handle high production volumes while preserving the identity and rights of professional voice talent.

The problem: scaling voiceover production without losing quality or rights

Producing advertising audio traditionally requires voice actors, studio sessions, editing, mixing, and mastering. For large retail campaigns, a single customer may require hundreds of voiceovers every month, and even small script revisions often mean scheduling new recording sessions. This created operational bottlenecks that limited how much work Fuzzr could take on.

Synthetic voices offered a faster alternative, but were not suitable for every project. Many brands rely on professional voice actors to represent their identity, which made voice quality, consistency, consent, and rights management non-negotiable requirements for any solution Fuzzr adopted.

Voice cloning that preserves actor identity and consent

Fuzzr built its production platform using ElevenLabs' Voice Cloning technology and APIs, integrating high-quality voice generation directly into its existing production pipeline. This allows advertising audio to be created using licensed voices from professional voice actors, with each voice created from recordings provided with consent and appropriate compensation. As a result, voice actors remain at the center of the production process while their voices can be used across more projects and formats than a traditional recording schedule would allow.

Voice cloning also lets approved voices generate content in additional languages, expanding what Fuzzr can produce for a given actor's voice without requiring new recording sessions.

Professional-grade audio quality, built for production at scale

The resulting workflow enables Fuzzr's production teams to process large batches of requests automatically. Scripts can be generated, voices synthesized, audio mixed, and final files prepared through a single production flow, reducing the manual steps that previously slowed down delivery on high-volume retail campaigns.

Our partnership with ElevenLabs has been crucial in enabling us to build proprietary audio tools at scale, with professional-grade quality and an engine that gives us confidence in delivery, quality, and compliance.

Natural Portuguese speech for the Brazilian market

ElevenLabs' support for natural Portuguese speech allows Fuzzr to maintain voice quality while producing content specifically for the Brazilian market, where accurate intonation and pronunciation are essential for advertising audio to sound credible to local audiences.

Extending voice infrastructure to conversational, customer-facing tools

The same infrastructure also supports customer-facing experiences such as Spot Bot, which allows users to generate advertising audio through conversational interactions on WhatsApp. This extends ElevenLabs' voice generation beyond internal production tooling into a direct interface for Fuzzr's customers.

Results

By integrating ElevenLabs into its production workflow, Fuzzr added AI voice generation to its advertising platform while continuing to work with licensed professional voices. The company now uses ElevenLabs' infrastructure to support high-volume production, reduce the need for repeated recording sessions following script revisions, and automate key stages of its audio production pipeline.

Today, ElevenLabs powers the voice layer behind Fuzzr's production platform, supporting the creation of thousands of advertising audio assets for the Brazilian market while preserving voice quality, operational consistency, and the use of authorized professional voices.
