How it works

We access our crowd of more than 110 million users of native speakers to collect, transcribe, and annotate voice data in your chosen language.

Every recording is validated and transcribed verbatim or non-verbatim using multiple humans to ensure highest quality.

Recordings are further classified depending on customer demand, such as background noise level, recording equipment, age groups, and we can collect other meta data.
The outcome is that you will get data delivered from up to hundreds of thousands of unique speakers at an unprecedented speed and reasonable price.

Thanks to our technology and massive crowd, our data has the highest variety and variance on the market.

We normally provide transcribed recordings in the range of 2s - 60s long depending on customer needs.
