    About this role

    Project Overview

    We are sourcing independent Audio Evaluation Specialists for an AI benchmark evaluation project assessing advanced agentic audio models. As AI models increasingly handle complex workflows in this domain—specifically real-world customer support scenarios like flight bookings, financial services, and telecommunications—their accuracy relies entirely on robust, expert-crafted training data. The objective of this project is to autonomously produce high-quality evaluation tasks through simulated interactions, audit conversational AI outputs, and generate clean, reliable datasets to optimize model performance.

    Project Deliverables & Scope

    Operate autonomously to design complex evaluation frameworks and provide structured training data. Expected deliverables include:

    Role-Play Scenario Execution: Creating and executing complex, role-play-based evaluation scenarios that simulate realistic customer service interactions across travel, finance, and technical support domains.

    Model Performance Auditing: Evaluating AI model performance across standardized qualitative and quantitative metrics, focusing strictly on task completion accuracy, conversational naturalness, and audio comprehension.

    Technical Metric Evaluation: Assessing the model's basic computer programming literacy, including its understanding of JSON structures, functions, methods, and ability to reason about structured data within a support context.

    Representative Dataset Generation: Contributing to the development of diverse, high-quality audio datasets that accurately reflect real customer expectations for clarity, efficiency, and natural conversational flow.

    Required Expertise

    To successfully fulfill the deliverables of this project, Contractors must possess deep industry knowledge to craft realistic professional scenarios. Core skillset includes:

    • Demonstrable professional expertise in complex customer support, technical troubleshooting, or conversational AI evaluation.

    • Native or bilingual proficiency in the target language, including fluency across all language skills (reading, listening, writing, and speaking), alongside strong analytical and verbal communication skills to confidently conduct simulated customer support role-plays.

    • Basic computer programming literacy, specifically a comfortable understanding of JSON structures, functions, methods, and simple logic.

    • A meticulous, detail-oriented approach to working with structured prompts, complex evaluation rubrics, and technical guidelines.

    Required Equipment: Access to a high-quality microphone to ensure clean, reliable audio input during voice evaluations.

    We offer a pay range of $6-to-$65 per hour, with the exact rate determined after evaluating your experience, expertise, and geographic location. Final offer amounts may vary from the pay range listed above. As a contractor you’ll supply a secure computer and high‑speed internet; company‑sponsored benefits such as health insurance and PTO do not apply.

    Engagement Type: Freelance / Independent Contractor

    Workplace Type: Remote
