Document Type and Number:
WIPO Patent Application WO/2024/029152
Kind Code:
A1
Abstract:
This delimiter insertion device comprises: a word-spacing time acquisition unit that acquires a word-spacing time, which is the length of time until the next word is uttered, for each word included in uttered speech; and a delimiter insertion unit that, on the basis of a delimiter insertion model and the word-spacing time, inserts a delimiter into target text, which is text obtained through speech recognition of the uttered speech. The delimiter insertion model outputs delimiter inference information indicating a delimiter in response to input of a delimiter removal sentence. The delimiter insertion unit inserts a delimiter into the target text on the basis of the delimiter inference information obtained by inputting the target text into the delimiter insertion model.
