Fecha de publicación: 15/12/2022 Fuente: WIPO (eseential oils OR extracts) This device for an online conference has a voice recognition unit (2013), a voice analysis unit (2014), an issue extraction unit (2015), and a display control unit (2016). The voice recognition unit converts a first voice collected from a terminal in an online conference into first text, and converts a second voice into a second text. The voice analysis unit disassembles the first text and the second text into word units. When a first co-occurrence matrix for a first word extracted from the first text and a second co-occurrence matrix for a second word extracted from the second text are similar, the issue extraction unit extracts the first word and the second word as a current issue in the online meeting. The display control unit synthesizes the extracted first word and second word into a screen for the online conference, and displays the screen for the online conference in which the first word and the second word are synthesized on the terminal.
