Claim 0:
1. A voice recognition method based on a neural network, performed by a computing device, the voice recognition method comprising:
receiving a video containing voice information;
generating first text data based on a first language based on the voice information; determining reliability of the generated first text data and detecting problem text with the reliability less than a set threshold;
detecting a second language corresponding to the detected problem text;
generating second text data based on the detected second language,
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, obtaining subtitle text of the part of the video based on OCR (Optical Character Recognition); and
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 determining the reliability of the generated first text data and detecting problem text with the reliability less than a set threshold includes;
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.
