English-Speaking JSON & Coding Experts for Audio Evaluations
TLDR
Evaluate AI-generated responses in live conversational scenarios, checking language quality, technical accuracy, JSON structure, and session artifacts.
Tasks include:
- Participating in live, real-time conversational scenarios with AI systems
- Reviewing and labeling conversation transcripts
- Evaluating AI-generated responses using structured rubrics and providing written justifications
- Assessing responses for language quality, customer experience, technical accuracy, formatting, and JSON structure
- Capturing required session artifacts, including recordings, Session IDs, and tool-call/console logs - Environment preparation and tool verification before each session
Experts should speak naturally and spontaneously, as if responding in real time, without pre-planned, written, or scripted responses - the client is evaluating natural voice cadence.
To be considered for this project, experts are required to pass a basic computational concepts assessment (JSON structures, function, general reasoning, and language proficiency), which takes about 15 minutes to complete, and will not be compensated. If the expert passes the assessment, they will be provided with further onboarding steps.
“Operator” requirements:
- Strong spoken-language proficiency: C1/C2-level fluency (CEFR) in the target evaluation language, verified through a speaking/listening assessment, not just a resume claim.
- Technical literacy: JSON fluency required - reading, validating, troubleshooting, and identifying structural/formatting issues
- Audio setup: capable of producing clear audio quality with no background noise
Ideal experts will have strong attention to detail, strong written communication skills, and the ability to evaluate both the customer experience and the technical correctness of a response. A solid understanding of JSON is especially important, including the ability to read, validate, troubleshoot, and identify structural or formatting issues.
