Audiobook QA Expert - European Portuguese (Remote)
Listing checked September 15, 2026 · pay as published by Mercor
Overview
Mercor needs native European Portuguese speakers to review AI-narrated audiobooks and judge how human the text-to-speech output sounds. You will listen with a fan's ear and an analyst's discipline, catching places where the narration stumbles so the models behind it can improve. The work is remote and part-time at about 20 hours per week, or around 4 hours per day. Candidates can live anywhere, though the team prefers people based in a region where European Portuguese is spoken natively.
What You'll Do5
- 1Review AI-generated audiobook narration in European Portuguese and rate how natural, accurate, and enjoyable each section feels.
- 2Catch and log speech errors such as skipped or added words, wrong pronunciations, misread numbers, abbreviations given the wrong expansion, odd intonation, and audio glitches.
- 3Assign a category to each issue and mark the exact time range where it occurs inside the review tool.
- 4Report on overall listener satisfaction and identify where the narration sounds human versus where it breaks the experience.
- 5Stay accurate across long listening sessions while keeping a part-time schedule of about 20 hours per week.
Requirements8
- 1Native or near-native fluency in European Portuguese.
- 2An active audiobook habit and real opinions about what makes a good listen.
- 3Working English for written reports and team communication.
- 4Experience with annotation, labeling, transcription, proofreading, linguistics, or another detail-heavy review task.
- 5A sharp, patient ear and the discipline to remain precise over many hours of audio.
- 6Availability for about 20 hours per week, about 4 hours each day.
- 7Nice to have: prior work on AI training data, model evaluation, or audio/QA annotation.
- 8Nice to have: a background in language, editing, voice, or audio production.
Who Should Apply
The ideal candidate is a native European Portuguese speaker who listens to audiobooks on a regular basis and can point to specific moments where a narrator succeeds or fails. Working English matters for reports, and some background in annotation, transcription, proofreading, linguistics, or similar review work will help you start strong. People who have touched AI training data, model evaluation, or audio QA projects often have an easier time with the review tooling and error categories. This role does not fit someone seeking full-time hours, unable to commit about 20 hours each week, or someone who treats audio as passive background noise. Applications tend to score lower when they show no real audiobook listening habit, no examples of detail-oriented review work, or fluency in Brazilian Portuguese rather than European Portuguese.
Salary Insight
The posted rate is $15.00 to $20.00 per hour. For remote part-time annotation and QA work, that range sits in a common band for language review projects, and the higher end often goes to candidates with prior model-evaluation or audio-annotation experience. No other compensation details appear in the source.
