Japanese Voice AI Evaluator (Healthcare Conversations)

Japanese 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 Japanese speakers in the Osaka area 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 for people with clear speech, sharp attention to detail, and an ear for what sounds natural in Japanese clinical settings — including the regional speech patterns of the Kansai area.

• 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 Japanese 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 mispronunciations (including kanji readings and pitch accent), cutoffs, interruptions, delays, and incorrect function calls, including timestamps

• Test how the AI handles background noise, short replies (「はい」「いいえ」「大丈夫です」), 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 Japanese 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 a clinical phone context

• 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 command of polite and honorific speech (敬語) as used in medical and service conversations

• Awareness of regional speech variation — including Kansai-area Japanese — and how it interacts with standard clinical register

• Linguistics or language-focused studies

• Familiarity with medical terminology in Japanese
