Job description

The role

We are seeking Fluent Spanish Speakers to act as evaluators. AI models are now learning to communicate with human-like nuance, and we need fluent speakers to ensure these models understand the cultural and emotional depth of the Spanish language.

You will be assessing how well an AI model captures human emotions, intonations, and sentiments in the US. This is a fast-paced project where your ear for detail directly influences how AI understands human feeling.

Researchers looking for your skills tend to pay up to $18/hr. You must be prepared to complete paid tasks that require one hour of uninterrupted work, though many are shorter.

What you’ll bring

• Fluency in Spanish: you must be a fluent Spanish speaker.
• Linguistic Nuance: an ability to distinguish subtle shifts in sentiment and vocal delivery.
• Communication: fluent English skills for instruction following and reporting.
• Soft Skills: high emotional intelligence; backgrounds in acting, therapy, or linguistics are a plus.
• Technical Setup: access to a quiet environment and high-quality audio equipment (headphones/speakers).

What you’ll be doing in the role

• Audio Localization: reviewing Spanish audio clips generated by or for AI models.
• Sentiment Analysis: assessing the model’s ability to convey specific emotions, intonations, and feelings.
• Quality Control: identifying where the AI's "tone" feels unnatural or culturally mismatched.
• Audio Assessment: listening to AI-generated or processed audio to verify "human-like" quality.
• Contextual Review: Identifying if the intonation matches the specific Indian cultural context of the conversation.
