Abstract: To provide a presentation assistance device that can display keywords related to presentation materials and call attention by displaying an alert when words that are forbidden to speak are spoken. A presentation assistance device 1 comprises: a presentation material storage means 3; a keyword storage means 5 which stores a plurality of keywords related to presentation materials; a related word storage means 7 which stores one or a plurality of related words for each of the plurality of keywords; an NG word storage means 9 which stores one or a plurality of NG words for each of the plurality of keywords; a voice recognition means 11; a term determination means 15 which determines whether a voice recognition term corresponds to a related word or an NG word; and a keyword output means 17 which when the voice recognition is a related word, outputs a keyword related to the related word, and when the voice recognition term is an NG word, outputs an alert and a keyword related to the NG word.

Abstract: [Problem] Provided is a presentation support system that makes it possible to give effective presentations, for both presentations by machines and normal presenters. [Solution] The presentation support system included: a display unit 3; a material storage unit 5 that stores a presentation material and a plurality of keywords; an audio storage unit 7; an audio analysis unit 9 that analyzes a term contained in a presentation; a keyword order adjustment unit 11 that analyzes an order of appearance of a plurality of keywords contained in the audio analyzed by the audio analysis unit and changes the order of the plurality of keywords on the basis of the order of appearance; and a display control unit 13 that controls content displayed in the display unit 3.

Abstract: To provide a system that ensures quickly and easily generating an appropriate incorrectly converted dictionary. An incorrect conversion dictionary generating system 1 includes a term input unit 3 to which a term is input, a voice data conversion unit 5 that converts an input term to voice data to obtain input-term voice data, the input term being a term input to the term input unit, a voice data analysis unit 7 that receives the input-term voice data output from the voice data conversion unit, performs a voice analysis to convert the input-term voice data to a term, and obtains a voice analyzed term, and an incorrectly converted term determining unit 9 that receives the input term from the term input unit or the voice data conversion unit, receives the voice analyzed term from the voice data analysis unit, and determines the voice analyzed term as an incorrectly converted term of the input term when the input term does not match the voice analyzed term.

Abstract: To provide a display information management system that greatly reduces the load of a management device when providing presentation screen information and the like created at each terminal, and the like to other terminals. A display information management system (1) includes a terminal device (50) including specific basic software (OS), specific information displaying software for creating a presentation screen operable with the specific basic software, and a database; and a management device (10), where the terminal can associate information of the database and each screen of the presentation, and create the presentation information created with the specific information displaying software with heterogeneous presentation information; and transmit the presentation information and the heterogeneous presentation information to the management device.
