Why label data?

Unlike traditional ASR systems, which are trained by meticulously editing sub-components of a data pipeline, our deep neural network improves with each data set it receives. Continuously train your speech model with the voice of your customers, and it will improve identification of sounds, and subsequently the words in new audio submitted.


Quickly and easily label audio — on-premise or in the cloud.

Upload pre-labeled files or label audio data as needed. Need to label onsite? No sweat. We’ll provide you with state-of-the-art labeling tools so that you can create accurate truth data for training, while keeping your data on-prem.

We couldn’t get these words right using Google, Amazon, or Speechmatics, and are thrilled to finally reach our accuracy goal with Deepgram.”
