Published on the November 12, 2026 in Design & Multimedia

About this project

Open

We are seeking parents, legal guardians, or recording studios in Mexico, Peru, and Costa Rica to facilitate voice recordings of children aged 5 to 15. These recordings are crucial for building a Spanish speech dataset, which will be used to train and evaluate advanced speech recognition systems.

Project Details:
- Each child will read 450 short sentences aloud in Spanish using our dedicated recording platform.
- The recording process is flexible and can be split into multiple short sessions with breaks, allowing for completion over time rather than in a single sitting.
- All recordings must be conducted in a quiet environment, free from background noise or echo, to ensure high audio quality.
- Comprehensive step-by-step instructions and ongoing support will be provided throughout the project.

Requirements for Participants:
- The contract will be established with an adult (parent, legal guardian, or studio representative) who will oversee the recording process.
- The adult must sign a consent form for the child and be present during all recording sessions.
- Participating children must be native speakers of their respective country's Spanish dialect (Mexican, Peruvian, or Costa Rican) and be fluent readers.
- Access to a phone or computer with a stable internet connection is required.
- We aim to achieve an equal representation of boys and girls in the dataset.

Compensation:
- Payment is 15 USD per child upon successful completion and approval of all 450 recorded sentences.
- Studios or families with multiple eligible children are encouraged to participate with each child.
