This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Spanish Audio Specialist - Freelance AI Trainer Project based in Brazil.

Join a specialized AI training project focused on assessing and benchmarking advanced agentic audio models against leading systems.

You will create realistic role-play scenarios that simulate customer support interactions across travel, financial services, telecommunications, and technical support.

Your work will help build diverse datasets used to evaluate conversational audio agents in real-world situations.

You will assess model performance across conversational, technical, and audio-specific criteria, including accuracy, naturalness, comprehension, and contextual understanding.

The role combines strong Spanish language expertise with clear verbal communication and an interest in structured, technology-driven evaluation.

You will work with prompts, evaluation rubrics, technical guidelines, and audio recording tools in a flexible remote environment.

This is an opportunity to contribute directly to the improvement of next-generation AI systems designed for customer-facing interactions.

Accountabilities:

• Create and execute role-play-based evaluation scenarios that realistically simulate customer service conversations across flight bookings and travel support, financial services, telecommunications, and technical support.
• Contribute to the creation of diverse and representative datasets used to assess and benchmark conversational audio agents.
• Evaluate model performance using standardized qualitative and quantitative criteria, including task completion accuracy, efficiency, conversational naturalness, tone, flow, coherence, and response quality.
• Assess audio comprehension, instruction adherence, contextual understanding, and the ability of models to handle realistic customer support scenarios.
• Apply evaluation rubrics consistently and ensure assessments reflect real customer expectations for clarity, efficiency, accuracy, and natural conversational flow.
• Use basic programming literacy to understand JSON structures, functions, methods, structured data, and simple logical relationships.
• Communicate technical observations clearly when evaluating support-style problem-solving and documenting model behavior.

Requirements:

• Strong fluency in English, combined with excellent verbal communication skills in simulated customer support environments.
• Professional-level Spanish proficiency across reading, listening, writing, and speaking.
• Strong ability to communicate naturally, clearly, and effectively in Spanish during realistic conversational scenarios.

• Strong attention to detail and the ability to evaluate conversational quality, contextual understanding, and technical responses consistently.
• Access to a high-quality microphone capable of providing clean and reliable audio input during evaluations.
• Access to a secure computer capable of running audio recording software and opening large technical documents.
• Ability to work independently while following detailed technical guidelines and evaluation standards.

Benefits:

• Compensation of $11 to $30.65 per hour, with the exact rate determined based on experience, expertise, and geographic location.
• Flexible remote contract work that can be performed from India.
• Opportunity to contribute to the evaluation and improvement of advanced agentic audio and conversational AI systems.
• Exposure to real-world AI benchmarking, customer support simulations, structured evaluation frameworks, and conversational technology.
• Contractor flexibility within a project-based environment.
• As a contractor, you will provide your own secure computer and high-speed internet.
• Company-sponsored benefits such as health insurance and paid time off are not provided for this contract role.
