Abstract
Techniques for augmenting automated speech recognition neural networks with scalable vocabularies are described. A cluster is selected from a plurality of clusters of similar sounding words based on a score, the score representing a similarity between an embedding of the cluster and an audio embedding of an utterance generated with an automated speech recognition encoder neural network. A bias factor is calculated based on a similarity between an embedding of a word in the selected cluster and the audio embedding. The audio embedding of the utterance is biased by the bias factor.
