Self-Supervised Learning: The science behind the magic.

At Speechmatics, we’ve pioneered a self-supervised learning approach to building our speech model. 

Speech models live and die by the data used to train them. Typically ASR models are trained only on labeled data, which drastically limits the available training data (as well as increasing its costs). In this case, labeled data is audio data that has been transcribed by a human – essentially creating a ‘ground truth’. This clearly limits the availability of labeled data, and when it comes to the nuances of speech and voice data, this is not ideal. When it comes to voice data, the more the better, since high accuracy can only be achieved by the models being trained on as wide a variety of voices as possible.

Unlabeled speech data on the other hand is abundant, but does not contain any additional information, and therefore is seen by most to be much harder to use to train speech models. Speechmatics are not most companies though, and we’ve achieved several breakthroughs that allow us to use unlabeled data and give us access to a far greater training dataset (over 1 million hours of multi-lingual data). This means more voices, more accents, more dialects, more noisy audio. 

When trained with self-supervised learning, our models can autonomously learn to spot salient patterns in the large quantities of unlabeled data. 

Just as children learn to speak a language by being exposed to a world of voices and conversation, our models also learn by the power of exposure with self-supervised learning. By finding hidden patterns present in unlabeled data, self-supervised learning allows us to efficiently learn to understand speech without needing massive amounts of time-consuming, costly and limited labeled data. 

This breadth of sources for training data ensure we achieve a high level of accuracy across all of our languages, which in turn increases the accuracy of any translation made using them.
