What You'll Do: Listen to AI-narrated Spanish audiobooks and assess naturalness, accuracy, and overall listener experience. Identify and log speech synthesis errors — including mispronunciations, skipped or added words, incorrect number reading, improper abbreviation expansion, unnatural intonation, and audio artifacts. Categorize each issue and mark the precise timestamp or span using dedicated review tooling. Provide overall satisfaction ratings and qualitative feedback on where narration feels natural versus where it disrupts the listening experience. Maintain consistent attention to detail across extended listening sessions. Who We're Looking For Native or near-native fluency in US / North American Spanish, with a genuine passion for audiobooks. Working proficiency in English sufficient for reporting and team communication. Prior experience in annotation, transcription, proofreading, linguistics, or similar detail-oriented review work. A patient, sharp ear and the discipline to stay accurate over long sessions. Reliable availability of approximately 20 hours per week on a part-time basis.

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 Spanish is natively spoken are strongly preferred.
