Korean Voice AI Evaluator – Native Speakers Wanted

Korean 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 Korean speakers based in the United States to hold natural spoken conversations with an AI healthcare receptionist, then evaluate how well it listens, responds, and takes action.

With one of the largest Korean-speaking diaspora communities in the world, the US is home to a wealth of native-fluency talent perfectly suited to this role. You'll role-play as a patient using fictional personas we provide, record short conversations, and grade the AI's performance — all from home, on your own schedule.

• 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 Korean 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 checking insurance

• Review transcripts and classify how accurately the AI understood you and responded

• Flag issues such as mispronunciations, cutoffs, interruptions, delays, and incorrect function calls, including timestamps

• Test how the AI handles background noise, short replies ("네," "아니요," "괜찮아요"), 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 Korean 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

• 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

• Strong sense of Korean speech levels and politeness (존댓말) in service conversations, and of how Korean numbers are read aloud (native vs. Sino-Korean)

• Linguistics or language-focused studies

• Familiarity with medical terminology in Korean
