We are looking for Sonic Audit Specialist - Hindi candidates for a project delivered through Mercor.
What you'll do
- Audit AI training data in Hindi.
- Listen to a recording of human or agent speech, read the transcription an annotator produced, and judge whether it accurately captures what the speaker actually said.
- Apply a fixed set of error codes, assign a pass or fail verdict, and write a short rationale explaining the decision.
- Review audio that has already been segmented at the word level by an automated system.
- Verify that the start and end timestamps match where the word actually begins and ends, and that the reference transcription matches the spoken form.
- Correct the boundary, split a segment, merge two, add a missing one, or remove one that contains no word.
- Tag every applicable error code and explain in plain language why the task passed or failed.
- Call out critical errors first so the reason for a failure is obvious to the reader.
What you need
- Native or near-native command of Hindi as spoken in India.
- Strong English reading and writing skills.
- Ability to apply a written standard consistently across hundreds of judgments.
- Careful listening skills, including distinguishing similar sounds, identifying word boundaries in continuous speech, and differentiating genuine acoustic ambiguity from clear annotator error.
Nice to have
- Prior transcription, subtitling, localization, linguistic annotation, or QA experience.
- Prior AI data annotation or model evaluation work.
- A phonetics or linguistics background.
- Experience with audio editing or waveform tools.
