AI speech & language data collection

Native Korean speakers. Real conversations. Reliable local operations.

9colors supports global AI companies, research organizations, and language technology teams with Korean participant recruitment, speech data collection, and local project coordination.

From speaker recruitment and studio coordination to recording management and quality checks, 9colors supports Korean speech data projects from start to finish.

What we can support.

Our strength is the local side of the work: finding the right Korean speakers and keeping each project running smoothly on the ground.

    Recruitment of native Korean speakers based on project-specific demographic, linguistic, and participation requirements.

    Korean-language content review, recording checks, and linguistic quality control, subject to project scope and requirements.

    Studio recording sessions

    For projects that need controlled, high-quality audio, we arrange sessions at rented professional recording studios in Korea and coordinate participants on site.

Why work with 9colors?

We are not a technology platform. What we bring is the operational work of connecting real people in Korea to your project, and seeing it through.

Local recruitment expertise

Our experience in Korean participant recruitment and qualitative fieldwork supports projects that need diverse participant profiles.

Human-centered operations

Clear instructions, steady participant communication, and consistent coordination, all in Korean.

Flexible project support

We can discuss pilot projects, small-scale recordings, and larger data collection requirements based on scope, resources, and timelines.

Parent and child speakers

Through the parent community we run ourselves, we can recruit parents and children as speakers, with guardian consent coordinated in Korean.

    Collection and quality checks

    We support the agreed deliverable handover and project completion procedures.

Consent and data use

The purpose of AI training use, participant consent, the scope of recording use, personal data handling, and delivery terms are confirmed for each project according to the contract and your requirements, and participants are informed in Korean before they take part.
