ELECTRONIC DEVICE, METHOD FOR ADAPTING ACOUSTIC MODEL THEREOF, AND VOICE RECOGNITION SYSTEM

摘要

An electronic device, a method for adapting an acoustic model thereof, and a voice recognition system are provided. According to one embodiment of the present invention, the electronic device comprises: a voice input unit for receiving a voice signal of a user; a storage unit for storing, therein, a transformer having a plurality of transformation parameters and an acoustic model having a parameter transformed by the transformer; and a control unit for generating a hypothesis from the received voice signal by using the acoustic model, estimating, by using the hypothesis, an optimal transformer having an optimal transformation parameter on which a voice feature of the user is reflected, and updating the plurality of transformation parameters of the transformer stored in the storage unit by combining the estimated optimal transformer with the transformer.
