About AI Training And Audio Evaluation

AI training is the human side of building artificial intelligence. People review, compare, label, and improve examples so AI systems can better understand language and produce useful results. In audio projects, human evaluators help models recognize high-quality speech and natural-sounding output.

  • Listen to and compare real or generated audio examples
  • Provide consistent human judgments using project guidelines
  • Contribute to the development of speech and language AI

The Role

As a Latin American Spanish Audio Preference Evaluator, you will listen to two audio recordings and select which option is better according to the project criteria. Your evaluations may focus on pronunciation, clarity, fluency, naturalness, accent appropriateness, and overall audio quality.

This is an intermediate-level contractor role for native or fluent Latin American Spanish speakers. The project is expected to run for 3 to 6 months, with a commitment of less than 20 hours per week.
