A project dedicated to assessing and benchmarking advanced agentic audio models against leading systems. The program’s mission is to evaluate and optimize model performance for real-world customer support use cases. Responsibilities

  • Flight bookings and travel support
  • Financial services

  • Contribute to the development of diverse and representative datasets used to assess conversational audio agents.
  • Evaluate model performance across a standardized set of qualitative and quantitative metrics.
  • Ensure evaluations reflect real customer expectations for clarity, efficiency, and natural conversational flow.

Evaluation Metrics Model performance is assessed using a combination of conversational, technical, and audio-specific criteria, including but not limited to:

  • Task completion accuracy and efficiency
  • Conversational naturalness (tone, flow, and coherence)
  • Audio comprehension and response quality
  • Instruction adherence and contextual understanding
  • Basic computer programming literacy, including:
  • Understanding of JSON structures
  • Familiarity with functions and methods
  • Ability to reason about structured data and simple logic
  • Technical communication clarity when handling support-style problem-solving

Technical & Equipment Requirements

  • Strong verbal communication skills in a simulated customer support context
  • Hindi proficiency including fluency across all language skills: reading, listening, writing, and speaking.
  • Access to a high-quality microphone to ensure clean, reliable audio input during evaluations
  • Comfort working with structured prompts, evaluation rubrics, and technical guidelines
  • Device capable of running audio recording software and opening large technical documentation

We offer a pay range of $11-to- $30.65 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.
