METHOD FOR BUILDING A DECODING NETWORK, METHOD AND DEVICE FOR SPEECH RECOGNITION, AS WELL AS DATA CARRIER Russian patent published in 2023 - IPC G10L15/18 

FIELD: computer technology for speech recognition.

SUBSTANCE: technical result consists in increasing the accuracy of recognizing the terms of a specific area. The technical result is achieved by forming a network for decoding a specific area based on a language model of a specific area and a universal language model; and combining the area-specific decoding network with the common decoding network to obtain the target decoding network, wherein the formation of the area-specific decoding network based on the area-specific language model and the universal language model includes: performing interpolation on the area-specific language model and the area-specific language model, wherein part interpolated on includes all parts in the domain language model and a part in the universal language model that also occurs in the domain language model; and generating a region-specific decoding network based on the part on which the interpolation has been performed.

EFFECT: accuracy of recognizing the terms of a specific area.
