Priscila de Cassia I.
Brazilian Portuguese | Audio QA, Review & Speech Evaluation
Hi! I’m Priscila — a native Brazilian Portuguese speaker from Brazil, fluent in English (IELTS 7.5), currently based in South Africa. I work with audio and language-focused AI projects, including audio data labeling, speech evaluation, and quality review. My work involves listening to recorded audio, assessing pronunciation, fluency, clarity, and natural speech, and following detailed evaluation guidelines. I also work as a Portuguese speech coach, where I review recorded submissions and provide feedback on pronunciation and natural speech patterns. This has given me a strong ear for detail and consistency in audio evaluation tasks. I’m reliable, detail-oriented, and comfortable working with structured workflows once I learn the criteria. I enjoy this type of work and value clear communication and long-term collaboration.
