About the role

AI Trainer - Spanish (Task-Based, Remote, Flexible)

Prolific Academic Ltd's standard text

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 Opportunity

We are looking for fluent Spnaihs speakers to help train the next generation of AI models - through real conversation. You'll join live video calls with other Spanish-speaking participants, chatting naturally about everyday topics while your conversation is used to help AI models better understand how people actually speak.

This is a genuinely interesting way to shape how AI understands human conversation, one call at a time - your natural way of speaking directly helps these models learn to communicate more like a real person.

This is a task based AI Training job that allows participants to choose their schedule and how much they work - there's no fixed schedule and no minimum hours requirement. Once you have joined the talent pool, you will be asked to complete a short assessment on your language skills. Passing this assessment also opens the door to similar paid projects in future.

Tasks

  • Video Conversations: Have live, natural conversations in Spanish with other participants over video call.
  • Natural Dialogue: Discuss everyday topics and let the conversation flow as it would with anyone else - no scripts, no performance.
  • Data Contribution: Your conversations are recorded and used to help AI models learn natural speech patterns, tone, and cultural nuance.

Tasks are posted individually - you'll see task details, time estimate and pay before deciding whether to take one on.

What You’ll Bring

  • Fluency in Spanish: you must be a fully fluent Spanish speaker.
  • Communication: fluent English for instructions and reporting.
  • A natural conversationalist: comfortable chatting easily and holding a flowing conversation over video call with someone new.
  • Technical Setup: a quiet environment and good-quality headphones/microphone, essential for clear audio and accurate data collection.
  • Soft Skills: friendly, easygoing, and comfortable talking with new people; backgrounds in teaching, interpreting, customer service, or linguistics are a plus.

Why Prolific is a great platform to join as a Participant

Joining our platform as a Prolific participant will give you the chance to influence the AI models of the future using your language expertise. Once you pass our assessment, you can join Prolific in just 15 minutes, and start enjoying competitive pay rates, flexible hours, and the ability to work from home.
