Audiobook QA Expert — Spanish; US; review AI outputs specialty

Overview

Help make the next generation of AI-narrated audio books sound genuinely human. We're building a team of native Spanish speakers who love audio books to help evaluate AI-narrated (text-to-speech) audio books in US / North American Spanish. You'll listen the way a real audiobook fan does - but with a careful, analytical ear - and flag the moments where the narration slips, so the underlying models can be made better.

This is remote, part-time work at roughly 20 hours per week (about 4 hours per day). You can be based anywhere, though we prefer people living in a region where Spanish is natively spoken.

• Listen to AI-narrated audio books in Spanish and assess how natural, accurate, and enjoyable the narration is.
• Spot and log errors in the synthesized speech - skipped, added, or mispronounced words; numbers read incorrectly; abbreviations expanded wrongly; unnatural phrasing or intonation; audio glitches and artifacts.
• Categorize each issue and mark the exact span where it occurs, using our review tooling.
• Report on overall listener satisfaction and where the narration feels natural versus where it breaks the experience.
• Work consistently and carefully across many hours of audio without losing attention to detail.

• Native or near-native fluency in Spanish (US / North American Spanish), and an active, genuine audiobook listener - someone who listens regularly and has real opinions about what makes a good listen.
• Enough working English to report clearly and communicate with the team (you do not need to be bilingual).
• Some experience with annotation, labeling, transcription, proofreading, linguistics, or other detail-oriented review work.
• A sharp, patient ear and the discipline to stay accurate over long listening sessions.
• Reliable availability of about 20 hours per week on a part-time basis.
• Nice to Have:
  Prior experience on AI training-data, model-evaluation, or audio/QA annotation projects.
• A background in language, editing, voice, or audio production.
