Mandarin Chinese Voice AI Evaluator (Healthcare Conversations)

Mandarin Chinese Voice AI Evaluator (Healthcare Front Desk Conversations)

About the Role

What if your voice could help teach AI how to handle a real phone call to a hospital or clinic? We're looking for native Mandarin Chinese speakers in Singapore to hold natural spoken conversations with an AI healthcare receptionist, then evaluate how well it listens, responds, and takes action.

You'll role-play as a patient using fictional personas we provide, record short conversations, and grade the AI's performance. This is a fully remote, flexible contract role suited to Singapore-based Mandarin speakers with clear speech, sharp attention to detail, and an ear for what sounds natural — whether your Mandarin reflects a Mainland, Taiwanese, or Singaporean background.

• Organization: Alignerr
• Type: Contract (task-based)
• Location: Remote
• Commitment: Flexible, work at your own pace

What You'll Do

• Hold 4 to 5 minute spoken conversations in Mandarin Chinese with an AI front desk assistant, playing a fictional patient
• Say natural trigger phrases to test whether the AI makes the correct function calls — for example, checking a patient record, booking an appointment, or verifying insurance
• Review transcripts and classify how accurately the AI understood you and responded
• Flag issues such as mispronounced words or tones, cutoffs, interruptions, delays, and incorrect function calls, including timestamps
• Test how the AI handles background noise, short replies (好的, 是的, 不用了), long numbers, emotional moments, and sensitive or unsafe requests
• Follow detailed labeling guidelines consistently and submit high-quality work

Who You Are

• Native or near-native Mandarin Chinese speaker with a clear, natural speaking voice
• Detail-oriented, with the patience to review recordings and transcripts closely
• Comfortable role-playing a patient and sounding authentic in spoken Mandarin
• Able to follow multi-step instructions and apply them consistently
• Reliable and self-directed when working independently
• Access to a quiet space, a good microphone, a stable internet connection, and a second device for playing background noise
• Comfortable using web-based tools

Nice to Have

• Experience in voice AI evaluation, data annotation, or QA testing
• Background in healthcare administration, customer service, or call center work
• Sensitivity to tones, regional accents, and natural colloquial Mandarin across Mainland China, Taiwan, or Singapore
• Linguistics or language-focused studies
• Familiarity with medical terminology in Chinese
