Are you an experienced voice actor eager to shape the future of AI? Large-scale language models and speech technologies are evolving rapidly, moving beyond simple interactions into expressive, human-like communication. With high-quality training data, tomorrow's AI can deliver more natural, accurate, and engaging voice experiences across education, entertainment, accessibility, and beyond. That training data begins with you—your voice expertise will help power the next generation of AI.

We're looking for a highly skilled voice acting professional who can bring nuance, clarity, and authenticity to training data in Portuguese. You'll work with cutting-edge AI tools, record and evaluate speech samples, and provide expert feedback on pronunciation, tone, pacing, emotional expression, and regional variation to strengthen Portuguese voice models.

On a typical day, you will record scripted material in Portuguese, assess AI-generated outputs for linguistic accuracy and naturalness, annotate errors, and collaborate with our team to refine prompts, evaluation methods, and voice design guidelines.

Demonstrated experience in professional voice acting, dubbing, narration, or related performance work in Portuguese is required. Experience in training, coaching, or linguistic annotation is a plus. Clear communication skills and attention to detail are essential. A high-quality recording setup—including a reliable microphone and a quiet environment—is required.

Ready to channel your Portuguese voice expertise into building the AI voices of tomorrow? Apply today and help shape the model that will speak to millions around the world.

We offer a pay range of $6 to $65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you'll supply a secure computer, high-quality microphone and recording setup, and stable internet connection; company-sponsored benefits such as health insurance and PTO do not apply.
