The role
We are hiring native and near-native Mandarin Chinese speakers to audit AI training data in their own language, not to produce it.
You will work across two Amazon Sonic audit collections:
Multilingual Transcription Audit. You 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. You apply a fixed set of error codes, assign a pass or fail verdict, and write a short rationale explaining the decision.
Forced Alignment Audit. You review audio that has already been segmented at the word level by an automated system. For each segment you verify that the start and end timestamps match where the word actually begins and ends, and that the reference transcription matches the spoken form. Where the machine got it wrong, you correct the boundary, split a segment, merge two, add a missing one, or remove one that contains no word.
Both collections run at 5.00 audit hours per task. Every judgment carries a written reason, so this is careful listening work rather than volume work.
Who we are looking for
Native or near-native command of Mandarin Chinese as spoken in mainland China. 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. This is a hard requirement.
Strong English reading and writing. All conventions, error codes, and audit rationale are written in English, so you need to read a detailed rulebook and write clear feedback in it.
Disciplined rubric application. The work rewards people who apply a written standard consistently across hundreds of judgments rather than relying on instinct. Prior transcription, subtitling, localization, linguistic annotation, or QA experience is a strong signal.
Careful listening. You can 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.
Helpful but not required: prior AI data annotation or model evaluation work, a phonetics or linguistics background, and experience with audio editing or waveform tools.
What the work looks like
You listen, judge, and submit. Where you find an error you tag every applicable error code, not just the first one, and you explain in plain language why the task passed or failed. Critical errors are called out first so the reason for a failure is obvious to the reader.
You will complete a short calibration phase before production work begins.
Requirements
- Must be eligible to work in one of: Remote, China
- Fluent proficiency in English (Written & Verbal)
- Reliable high-speed internet connection
How long hiring takes
Across the AI training platforms we refer candidates to, the median gap between referral and hire is about 30 days. It varies by platform and role, so treat it as a rough guide for this one.

Common questions
Is Mercor for freelancers or full-time contractors?
Mercor places you with one client for a defined engagement, like 'Python Tutor for 3 months', rather than having you grab small tasks from a shared queue. Most roles function as steady contract work, not one-off gigs.
Does Mercor's application require an on-camera interview?
Yes, every applicant records a video interview with an AI interviewer that asks questions about your resume. Clients review that recording to judge communication skills before matching, so there's no way to apply without going on camera.
What does asynchronous AI training work mean in practice?
No set hours, no check-ins, no meetings. You log in when you want, pick up an available task, complete it, and submit; nobody is waiting on you in real time. That's different from remote employment, where you're expected online during business hours. The tradeoff: you're competing with others for available tasks, so an empty queue means there's simply nothing to do until more work is released.
What does Languages work look like for a Sonic Audit Specialist - Chinese?
Tasks here are scoped to Languages, not generic labeling. As a Sonic Audit Specialist - Chinese, expect to draw on real domain judgment (evaluating outputs, correcting errors, or providing expert reasoning specific to Languages) rather than following a one-size-fits-all rubric. If you don't have hands-on Languages background, this is likely not the right listing to start with.
What specific skills does this listing call for?
Chinese, English, Mandarin, and Multilingual are named directly in the listing. If you don't have hands-on experience with these, expect the screening process to test for them directly rather than accepting adjacent experience as a substitute.
How much does this specific role pay?
This listing is posted at $22/task, a per-task rate. Pay can change between when we last checked the listing and when you apply, so confirm the current number on the platform's own application page before committing time.
Do I need to be fluent in Chinese, English, or Mandarin?
Yes. This role specifically requires Chinese, English, or Mandarin proficiency, on top of the English most AI training work assumes by default. If Chinese is not a language you're fluent in, this is not the right role. Filter for your native language to find better-matched listings.
How does per-task pay translate to an hourly rate?
It doesn't directly, that's the catch. Each task has a listed price and an estimated completion time, but your actual effective rate depends on how fast you work. If a task is estimated at 20 minutes and pays $8, that is $24/hr for a fast worker and $12/hr for a slow one. Track your actual time on the first few tasks before treating the listed rate as your real hourly income.
What happens when I click Apply on this listing?
You'll be taken to Mercor's external site to complete your application there. This listing links through a referral, but the process is identical to applying directly; the link just routes you correctly. Create an account on their site and follow their onboarding steps.
Can I apply from outside China?
This specific role is open only to people based in China. If you are somewhere else, applying is unlikely to lead to an offer even if you pass the assessment, because the restriction is usually about where the work can legally be contracted rather than your skills. Read the full description for any tax-residency or right-to-work caveats before you apply.
How soon will I start working after applying to Mercor?
Not immediately. Mercor is a talent marketplace, not a task queue, so applying puts you in a pool of candidates. You start working only once a specific client, like a major AI lab, selects your profile, and that matching process can take weeks.
