Jennifer M.

Brazilian Portuguese Language Specialist | AI Evaluation

I’m a native Brazilian Portuguese speaker with over four years of professional experience in language services, including projects involving both audio and written content. My AI evaluation work includes reviewing Brazilian Portuguese audio and TTS samples, comparing samples, checking transcripts, and identifying inconsistencies between audio and text. I can provide clear, specific feedback when something sounds or reads unnatural, even when the issue is subtle. I also have experience with data annotation. Beyond AI evaluation, I have experience with Brazilian Portuguese transcription, subtitling, localization, proofreading and editing, content review, and English-to-Brazilian Portuguese translation and adaptation. Services: • AI evaluation, including audio and TTS • Transcription • Data annotation • Subtitling • Brazilian Portuguese localization • Proofreading and editing • Content review • English-to-Brazilian Portuguese translation/adaptation
