Audiobook QA Reviewer - Brazilian Portuguese
Listing checked September 15, 2026 · pay as published by Mercor
Overview
Mercor builds a team of native Brazilian Portuguese speakers to judge AI-narrated audiobooks. You will listen to text-to-speech narration and mark where pronunciation, pacing, or audio quality fails. The role runs remote for about 20 hours each week, about 4 hours per day. Candidates based in Brazil get preference, though the work is open to any location.
What You'll Do5
- 1Review AI-narrated audiobooks in Brazilian Portuguese and rate how natural, accurate, and engaging each one sounds.
- 2Identify speech errors such as skipped words, added words, mispronunciations, wrong number reading, bad abbreviation expansion, odd intonation, and audio artifacts.
- 3Label every issue by category and mark the exact audio segment where it happens using the review platform.
- 4Document listener satisfaction and note which passages feel human versus which ones disrupt the experience.
- 5Sustain focus across long listening sessions while keeping error reports consistent.
Requirements8
- 1Native or near-native command of Brazilian Portuguese.
- 2Active audiobook listener with real opinions about narration quality.
- 3Working English for clear reports and team communication. You do not need to be bilingual.
- 4Experience in annotation, labeling, transcription, proofreading, linguistics, or similar review work.
- 5Sharp, patient ear and discipline to stay accurate over extended audio review.
- 6Availability around 20 hours per week on a part-time basis.
- 7Prior work on AI training data, model evaluation, or audio QA annotation.
- 8Background in language, editing, voice, or audio production.
Who Should Apply
The right person listens to audiobooks in Brazilian Portuguese as a habit and can explain why a narrator sounds off. You have some annotation, transcription, proofreading, or linguistics background and can write clear English reports about audio issues. This role fits someone who can commit about 20 hours per week and keep focus through hours of listening. The job does not suit people who want full-time hours, lack native-level Brazilian Portuguese, or dislike repetitive review tasks. Candidates often lose fit when they cannot point to specific audio QA or annotation work, or when they call themselves audiobook fans without showing analytical listening habits.
Salary Insight
Pay ranges from $15.00 to $20.00 per hour. That band matches entry-level to junior annotation and QA work, though native language skill and audio review experience can push candidates toward the upper end. This hourly range sits near typical pay for part-time language and audio annotation projects, with the top of the band often reserved for reviewers who bring prior AI data or audio QA experience.
