Abstract
Systems and methods are described for converting speech to text. In one aspect, a method for converting speech to text includes generating an initial transcript of an audio or video file. At least one named entity may be extracted from the initial transcript using entity recognition. A subset of nodes of a knowledge graph that include the at least one named entity may be selected, where the subset of nodes of the knowledge graph correspond to a set of named entities. The method may further include encoding the set of named entities to generate a set of entity embeddings. The speech in the audio or video file may then be decoded using the set of entity embeddings to produce a final transcript of the audio file.
