Title: Speech recognizing method
Inventor: TAKAHASHI KATSUNORI
IPC: G10L15/06
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To properly classify the constitution of a word dictionary and to efficiently recognize a speech by relating a word which represents a group as a main word and other words as synonyms for the main word and recognizing even a synonym inputted as an input speech similarly as the main word which is inputted. SOLUTION: To give flexibility so that the word dictionary is easy for a user to speak and usable even for other on-vehicle equipment, the word dictionary is classified by categories of 'of which on-vehicle device (unit)', 'what (purpose)', and 'how (operation)' and words having the same meanings in the respective categories are grouped. For, e.g. an air-conditioner, if words 'air-con', 'cooler', 'heater', 'ir-conditioner' and 'air-conditioning'... are registered as an 'air-conditioner' group, then even when the word 'cooler', 'heter'... or the like is inputted, the group is recognized similar to the case when the word 'air-conditioner' is inputted.

Abstract: PROBLEM TO BE SOLVED: To enhance printing speed without sacrifice of print accuracy by arranging a plurality of print heads in the printing direction while shifting each print head sequentially in the printing direction by an amount corresponding to a plurality of intervals of ink nozzle thereby constituting a set of ink jet heads. SOLUTION: A print head 1 comprises a large number of ink nozzles 5 opening linearly in the print window thereof wherein a plurality of print heads, e.g. three print heads 1a-1c, are arranged in the printing direction as a set of an ink jet head A.
