A call registration device for an elevator which performs a call registration by voice recognition using a voice input section which receives the input of a voice uttered by a user of the elevator, comprising: a voice recognition section which stores beforehand voice data of a predetermined call registration command representing a destination floor or direction of the call registration and voice data of a predetermined start command which is used for starting voice recognition of a call registration command, and which is different from the call registration command and does not include the call registration command, wherein the voice recognition section also performs the voice recognition by judging whether or not a voice inputted to the voice input section matches either the voice data of the stored call registration command or the voice data of the start command; a call registration control section which, in the case where the voice inputted to the voice input section was judged to match the voice data of the call registration command, outputs to an elevator control device a call registration request to the destination floor or direction represented by the relevant matched call registration command with; a start command changing part which changes, according to predetermined condition [which includes at least a point as to whether or not a present time belongs to a time division of the day determined beforehand], the start command which becomes effective among the start commands stored by the voice recognition section, wherein in the case where the voice recognition section judges that the voice inputted to the voice input section matched the voice data of the start command made effective by the start command changing part, the voice recognition section starts the voice recognition as to whether or not the voice inputted to the voice input section matches the voice data of the call registration command. a voice recognition section which stores beforehand voice data of a predetermined call registration command representing a destination floor or direction of the call registration and voice data of a predetermined start command which is used for starting voice recognition of a call registration command, and which is different from the call registration command and does not include the call registration command, wherein the voice recognition section also performs the voice recognition by judging whether or not a voice inputted to the voice input section matches either the voice data of the stored call registration command or the voice data of the start command; a call registration control section which, in the case where the voice inputted to the voice input section was judged to match the voice data of the call registration command, outputs to an elevator control device a call registration request to the destination floor or direction represented by the relevant matched call registration command with; a start command changing part which changes, according to predetermined condition [which includes at least a point as to whether or not a present time belongs to a time division of the day determined beforehand], the start command which becomes effective among the start commands stored by the voice recognition section, wherein in the case where the voice recognition section judges that the voice inputted to the voice input section matched the voice data of the start command made effective by the start command changing part, the voice recognition section starts the voice recognition as to whether or not the voice inputted to the voice input section matches the voice data of the call registration command.
