Electronic device and method for controlling same

A method performed by an electronic device, the method comprising:

• obtaining, by the electronic device, first audio data including a user voice;
• obtaining, by the electronic device, second audio data through acoustic augmentation on the first audio data;
• obtaining, by the electronic device, a first section corresponding to audio data between time points at which a user speech is included among the first audio data and a second section of the second audio data corresponding to the first section;
• calculating, by the electronic device, a plurality of first scores corresponding to each of a plurality of estimation candidates based on the first audio data corresponding to the first section;
• calculating, by the electronic device, a plurality of second scores corresponding to each of the plurality of estimation candidates based on the second audio data corresponding to the second section;
• and
• determining, by the electronic device, one estimation candidate among the plurality of estimation candidates as character data based on the plurality of first scores and the plurality of second scores.

One or more non-transitory computer-readable storage media storing one or more computer programs including computer-executable instructions that, when executed by one or more processors of an electronic device individually or collectively, cause the electronic device to perform operations, the operations comprising:

• obtaining, by the electronic device, first audio data including a user voice;
• performing, by the electronic device, acoustic augmentation on the first audio data to obtain second audio data;
• obtaining, by the electronic device, a first section corresponding to audio data between time points at which a user speech is included among the first audio data and a second section of the second audio data corresponding to the first section;
• calculating, by the electronic device, a plurality of first scores corresponding to each of a plurality of estimation candidates based on the first audio data corresponding to the first section;
• calculating, by the electronic device, a plurality of second scores corresponding to each of the plurality of estimation candidates based on the second audio data corresponding to the second section;
• and
• determining, by the electronic device, one estimation candidate among the plurality of estimation candidates as character data based on the plurality of first scores and the plurality of second scores.
