20 Claims

1. An electronic device comprising:

a processor; and

a memory operatively connected to the processor,

wherein the memory stores instructions that, when executed, cause the processor to:

receive a voice input of a user,

extract a feature from the voice input of the user,

select an acoustic model through comparison with the extracted feature, and

perform fine-tuning on the selected acoustic model based on an utterance-induced value, so that the selected acoustic model learns the feature of the voice input, and

wherein the utterance-induced value includes a threshold value for determining a similarity between an utterance-induced text and an obtained text.
