AI Evaluator and Data Annotator evaluating Portuguese AI text and speech for quality, clarity, and naturalness.
BrazilIn my independent project work, I evaluate AI-generated text and speech for relevance, coherence, and adherence to instructions. I compare model responses, document quality judgments with evidence, and review Portuguese grammar, clarity, and tone.
I also assess text-to-speech pronunciation and naturalness, and review voice interactions for timing and continuity. My completed bachelor’s degree in Library Science supports my work in information organization, classification, and research.
