Sonic Audit Specialist - Japanese

• 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 where the machine got it wrong.
• Tag every applicable error code, not just the first one, 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.
• Complete a short calibration phase before production work begins.

• Native or near-native command of Japanese as spoken in Japan. You were either born and raised in a region where this language and variety is dominant, or you are fully fluent with five or more years of residence in such a region.
• Strong English reading and writing skills.
• Disciplined rubric application. Ability to apply a written standard consistently across hundreds of judgments rather than relying on instinct.
• Careful listening skills. Ability to distinguish similar sounds, identify where one word ends and the next begins in continuous speech, and tell genuine acoustic ambiguity apart from a clear annotator error.

• 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.
