The work

You will review 30- to 90-second field recordings with quality headphones in a quiet workspace. Your work will turn what you hear into clear, structured information for AI training.

You will also compare recordings, evaluate AI-generated descriptions, and explain your decisions in concise written notes.

• Identify instruments, tempo, musical key, background sounds, crowd reactions, and scene details.
• Record timestamps for background events and other audio details using dropdowns, timestamps, and structured notes.
• Compare paired recordings of the same song from different locations and identify what stayed consistent or changed.
• Mark AI-generated audio descriptions as correct, incorrect, or invented, with a short explanation for each judgment.
• Take part in a paid onboarding and calibration session and a short weekly sync.

About AI training work

AI training work is the human side of building artificial intelligence. People review audio, text, images, and model responses so AI systems can learn from accurate examples, and specialized experience matters when the task requires careful subject knowledge.
