The work

You will review Spanish audio clips and model outputs to judge whether speech sounds fluent, natural, and linguistically authentic. Your work will support improvements in how language systems understand and generate Spanish.

  • Rate speech and model outputs using established project guidelines.
  • Write clear English feedback and detailed reasons for each decision.
  • Clarify ambiguous language content with project coordinators when needed.
