I’m a bilingual voice actor (Brazilian Portuguese and American English), passionate about using my voice to connect, inspire, and tell stories. I record professional voiceovers for commercials, e-learning, video games, audiobooks, guided meditations and sleep stories, virtual assistants, and corporate narrations. My goal is always to bring authenticity, clarity, and emotion to every project—whether I’m giving voice to a global brand, a video game character, or a training module.
Beyond voiceover work, I also collaborate on audio localization, script adaptation, and studio direction. I enjoy sharing what I’ve learned through workshops and one-on-one mentoring, helping other professionals develop their vocal presence.
My journey with voice began during my training as an actress at EAD/USP, where I fell in love with the power and versatility of the human voice. I was lucky to learn from masters like Mônica Montenegro, Carmina Juarez, and Isabel Setti, who inspired me to explore tone, rhythm, and breath to bring characters to life.
In theater, I became highly attentive to the vocal choices actors made—their truth, technique, and delivery—and developed a sharp ear for distinguishing genuine performances from disconnected ones. Without realizing it, I was already preparing myself for a career in voice acting.
In 2017, I moved to San Francisco to work on a voice project with one of the world’s largest tech companies. That opportunity was a turning point, expanding my professional reach and reaffirming everything I had built up to that moment. Not long after, I decided to make California my permanent home, so I could be closer to work and expand my activities beyond Portuguese. Since then, I’ve been working as a multilingual voice actor, building a career that blends technique, versatility, and passion for voice.

Home Studio
(Equipment & Recording Setup)
I record professional voiceovers from my home studio, delivering broadcast-quality audio for clients anywhere in the world.
Equipment I use:
- DAW: Pro Tools or iZotope RX 8
- Microphones: Sennheiser 416 and Aston Origin
- Interface: Focusrite Scarlett
- Source-Connect
Most projects can be recorded and delivered within 24 hours, and in many cases, same-day turnaround is possible. I send audio in the format you prefer (WAV, AIFF, MP3, etc.) through email, Dropbox, WeTransfer, or Google Drive. Source-Connect is also available for live sessions.
My background in theater, improv, and on-camera work taught me how to create believable characters, adapt quickly, and follow direction with ease—skills that make every recording session smoother.
Voice style: Warm, engaging, balanced resonance, with a smooth and velvety tone.
I’m based in the United States and record in both English (American) and Brazilian Portuguese, either from my professional home studio or in studios in the Bay Area. I’m also available to travel, and can fly to Los Angeles anytime for dubbing or voiceover projects.
