Audiobook QA Expert – European Portuguese | $15–20/hr | Remote (Portugal Preferred)

Join a growing team helping shape the future of AI-narrated audiobooks. We're looking for native European Portuguese speakers who are passionate about audiobooks and have a sharp, analytical ear to evaluate and improve AI text-to-speech narration. This is a part-time, remote role at approximately 20 hours per week.

What You'll Do

- Listen to AI-narrated audiobooks in European Portuguese and assess naturalness, accuracy, and overall listening quality.

- Identify and log speech errors — including mispronunciations, skipped or added words, incorrect number readings, wrongly expanded abbreviations, unnatural phrasing, and audio artifacts.

- Categorize each issue and mark the exact timestamp or span using our internal review tooling.

- Provide overall listener satisfaction feedback, noting where narration feels natural and where it disrupts the experience.

- Maintain consistent attention to detail across extended listening sessions.

Who We're Looking For

- Native or near-native fluency in European Portuguese with a genuine habit of listening to audiobooks.

- Working proficiency in English sufficient for reporting and team communication.

- Prior experience in annotation, labeling, transcription, proofreading, or other detail-oriented review work.

- Patient, disciplined, and capable of sustaining accuracy over long listening sessions.

- Reliable availability of approximately 20 hours per week.

Nice to Have

- Experience with AI training data, model evaluation, or audio/QA annotation projects.

- Background in linguistics, editing, voice acting, or audio production.

This is a remote, part-time contractor role. Candidates based in regions where European Portuguese is natively spoken are strongly preferred.
