Native-language data collection
Text and speech produced by native speakers, including regional dialects and natural code-switching.
Multilingual AI Data
Multilingual data from native speakers, not machine translation
Models that work well in English often break on dialects, code-switching and cultural context. One6 works with native speakers to collect, transcribe, localize and evaluate data so your model behaves correctly for the people who will actually use it.
What we deliver
Transcription and translation
Human transcription and translation that preserves meaning, tone and domain terminology.
Localization review
Checks that content, prompts and model output read naturally and appropriately in each target market.
Multilingual model evaluation
Native speakers rate and correct model responses for fluency, accuracy and cultural fit.
Common use cases
- Extending an LLM or assistant to new languages
- Testing model quality in markets before launch
- Building speech datasets for lower-resource languages
- Reviewing machine-translated training data
How a project works
- 01
Scope
A short call to understand your model, data requirements, quality bar and timeline.
- 02
Pilot
A small first batch so you can review real output before committing to volume.
- 03
Scale
Once the pilot meets the agreed bar, we staff up and deliver in regular batches with ongoing QA.
Frequently asked questions
Which languages do you support?
Coverage depends on the project's language and dialect requirements. Tell us the languages you need and we'll confirm availability and contributor profiles during scoping.
Are contributors native speakers?
Yes — language work is staffed with native or near-native speakers of the target language and, where relevant, the specific regional variety.
