We’re hiring freelance AI Data Annotators for Spanish language alignment work.
You'll listen to audio and align spoken words to their exact position in the transcript - correcting boundaries, catching mis-transcriptions, and making sure every word lands where it belongs.
The work is detail-heavy and quiet. If you like careful, focused tasks and have a good ear for language, it's a strong fit.
Fully remote and fully adaptable. No fixed schedule and no minimum weekly commitment. You pick up tasks when they're available and deliver against a deadline - mornings, nights, weekends, whatever works for you.
What you'll be doing:
- Listening to audio and aligning each word in the transcript to where it's actually spoken
- Correcting timing boundaries, missing or extra words,



and transcription errors
- Applying detailed annotation guidelines consistently across large volumes of work
- Flagging unclear audio, edge cases, and anything the guidelines don't cover

What you'll need:
- A laptop or desktop computer. This work can't be done on a phone or tablet.
- Headphones and a quiet environment. You'll be listening closely to short segments of speech, often repeatedly.
- Strong Spanish writing and comprehension. You should be comfortable reading detailed guidelines and picking up on subtle differences in wording.
