Abstract

An elevator control device is provided with: a microphone (6) from which the voice of a passenger in a car (1) is inputted; a storage unit (15) in which, regarding a destination floor designation operation by which the passenger designates a destination floor by voice, a predetermined first keyword indicating the start of the operation and a predetermined second keyword indicating the destination floor are stored; a voice recognition unit (11) which compares the voice inputted from the microphone (6) with the first and second keywords stored in the storage unit (15); and a control unit which registers the designation floor corresponding to the second keyword if the voice recognition unit (11) recognizes the second keyword after recognizing the first keyword when the door (2) of the car (1) is fully opened or fully closed, and the control unit outputs a command for stopping the opening and closing movement of the door (2) of the car (1) until the destination floor designation operation is finished after the voice recognition unit (11) recognized the first keyword.

Description

technical field [0001] The invention relates to an elevator control device for passengers in a car to register a destination floor by voice. Background technique [0002] It is known that in a conventional elevator control device, when a voice spoken by a user is input to a voice input unit such as a microphone installed in a car, the input voice is recognized to identify the destination floor spoken by the user. register. However, in an elevator control device that registers a destination floor by such speech recognition, misrecognition of speech may occur due to the influence of environmental noise in the car or the like. [0003] In contrast, for example, in Patent Document 1, in order to suppress false registration of a call caused by a voice other than the voice spoken by the user for call registration, when the user inputs a start command indicating the start of voice recognition After the voice, the input call registration command is recognized as the destination fl...
