Our Data Powers Your Innovations


Real-world products require real-world data. To properly train your AI, you’ll need data from the environments in which your product or solution will actually be used.


Whether it’s audio of a certain frequency, images under certain lighting, or videos at a particular angle, most machine learning projects require highly specific or varied input data.


Many machine learning projects require huge quantities of data from all around the world, collected on a tight timeline. Remote data collection makes that lofty goal a reality.

Data Collection

Summa Linguae collects a wide variety of data for AI-powered products, including fitness wearables, voice assistants, autonomous vehicles, and more.

Speech Data

How do we collect data?

In-Person Data Collection

Projects with complex requirements—like a specific microphone or camera—are best-suited for in-person data collection.

We travel across the world to collect specialized data in different languages and countries. We’ve recorded data in cars, warehouses, while athletes trained, and even at dinner parties.

If you need a specialized scenario with specific requirements, we can make it happen.

Remote Data Collection

Need lots of data—and fast? Your project is likely best-suited for remote data collection.

We’ve built the technology to quickly gather a wide variety of data from a worldwide database of diverse users from our proprietary mobile app.

Whether you need thousands of speech samples in a particular accent, pictures of receipts in a specific country, or videos of everyday life, Summa Linguae can provide high-quality, thoroughly vetted data to suit the needs of your project.
