Classification: CPC G | IPC G

Claim 8:
9. A computer program stored in a non-transitory computer readable storage medium, in which when the computer program is executed by one or more processors, the computer program causes the one or more processors to perform operations for voice recognition, the operations comprising:
an operation of receiving a video containing voice information; an operation of generating first text data based on a first language based on the voice information;
an operation of determining reliability of the generated first text data and detecting problem text with the reliability less than a set threshold among the generated first text data;
an operation of detecting a second language corresponding to the detected problem text; and
an operation of generating second text data based on the detected second language;
an operation of determining the presence of subtitles in a part of the video corresponding to the problem text in the video;
when subtitles exist in the part of the video, an operation of obtaining subtitle text of the part of the video based on OCR (Optical Character Recognition); and
an operation of outputting the obtained subtitle text together with the second text data in a part corresponding to the problem text;
wherein the second language is different from the first language,
wherein the operation of determining the reliability of the generated first text data and detecting problem text with the reliability less than a set threshold includes:
an operation of deriving reliability for each of texts in chunk units for the first language and detecting text in chunk units having reliability less than the set threshold as the problem text.
