About Prolific

Prolific is not just another player in the AI space. We are building the biggest pool of quality human data in the world. Over 35,000 AI developers, researchers, and organizations use Prolific to gather data from paid study participants with a wide variety of experiences, knowledge, and skills.

The Role

We are seeking fluent Spanish speakers from Spain, Argentina, Chile, Mexico, and Colombia to participate in a high-impact AI training initiative for our client, Hume. Unlike standard data entry, this role focuses on the nuance of human-to-human connection.

You’ll be paired with another participant for live video conversations to help train the next generation of empathic AI. By capturing natural emotions, intonations, and cultural sentiments, you are helping the model understand how humans truly communicate.

What you’ll be doing

Live pairings: You will be matched with another participant for 1-on-1 conversational video calls.
Emotional Authenticity: Engage in natural dialogue to help the AI model understand human feelings, intonations, and sentiment.
Audio-Visual Contribution: Ensure high-quality data capture by using a MacBook or headphones in a quiet environment.
Collaborative Learning: Help the AI understand the regional nuances, slang, and cultural contexts of your specific Spanish dialect through real-world interaction.

What you’ll bring

Fluency in Spanish: You must be a fluent Spanish speaker from one of the specified regions (Spain, Argentina, Chile, Mexico, or Colombia).
Technical Readiness: Access to a MacBook or headphones is mandatory for audio clarity.
Availability: Ability to commit to at least 5 hours of conversation per week.
Reliability: Since you are being paired with a live partner, punctuality and a stable internet connection are mandatory.
Soft Skills: Comfort chatting on camera and the ability to maintain a natural, flowing conversation.

Why join this project? This is a unique opportunity to act as a linguistic and emotional guide for one of the most significant AI projects of 2026. You are providing the "human spark" that makes AI more relatable, empathic, and accurate across the Spanish-speaking world.
