Embodiment approach 1

[0031] Generally, elevators are installed in buildings such as buildings. A call registration device is provided in the car or landing of the elevator. A user registers an elevator call using the call registration device. Then, the car of the elevator moves up and down in response to the call registered by the call registration device.

[0032] Here, a voice call registration device for registering an elevator call by voice input has been proposed as one of the call registration devices. This voice call registration device recognizes the voice uttered by the user in the car or at the hall, and registers the call of the elevator. If this voice call registration device is used, even a user with both hands occupied can easily register an elevator call.

[0033] In such a voice call registration device, if the voice uttered by the user is misrecognized, the elevator call desired by the user cannot be registered. Therefore, in the voice call registration device of this embodime...

Embodiment approach 2

[0062] Figure 4 It is a configuration diagram of a voice call registration device and an elevator control unit of an elevator according to Embodiment 2 of the present invention. In addition, the same code|symbol is attached|subjected to the part which is the same as or equivalent to Embodiment 1, and description is abbreviate|omitted.

[0063] The voice call registration device of the second embodiment is a device in which the user information storage unit 15 is added to the voice call registration device of the first embodiment. This user information storage unit 15 has a function of storing the second user tendency information by associating and storing the extracted user information and elevator information every time the user information extraction unit 6 extracts user information.

[0064] That is, in Embodiment 2, the user information storage part 15 learns 2nd user tendency information in conjunction with elevator information. And, the learning result thereof is refl...

Embodiment approach 3

[0070] Figure 4 It is a configuration diagram of a voice call registration device and an elevator control unit of an elevator according to Embodiment 3 of the present invention. In addition, the same code|symbol is attached|subjected to the part which is the same as or equivalent to Embodiment 1 or 2, and description is abbreviate|omitted.

[0071] In the voice call registration device of Embodiment 3, a voice feature extraction unit 16, a voice feature storage unit 17, and an input voice learning unit 18 are provided instead of the information input unit 5, user information extraction unit 6, building information Storage unit 7 .

[0072] The speech feature extraction unit 16 has a function of extracting speech features from the feature quantity data converted by the acoustic analysis unit 4 . The voice characteristics are classified into voices of adults, voices of children, voices of women, voices of men, and the like. That is, in Embodiment 3, the speech characteristic...

Abstract

Provided is a voice call registration device for an elevator, wherein the possibility of selecting an acoustic model that matches the feature of a user when a call for the elevator is registered by a voice input can be increased by an easy method without limiting users. The voice call registration device for the elevator is configured to be provided with a voice input unit which takes in input voice to a voice input device provided in the car or at the platform of the elevator, an acoustic model storage unit which stores a plurality of acoustic models having different acoustic characteristics, a user information extraction unit which extracts user information relating to the feature of a user present in the car or at the platform provided with the voice input device, an elevator information extraction unit which extracts elevator information relating to the elevator state including the position of the car or the platform provided with the voice input device, and an acoustic model selection unit which on the basis of the user information and the elevator information, selects from among the plurality of acoustic models an acoustic model to be used when the call for the elevator is recognized from the input voice.

Description

technical field [0001] The present invention relates to a voice call registration device for an elevator that registers elevator calls by voice input. Background technique [0002] Regarding a voice call registration device for registering an elevator call by voice input, a device having a plurality of voice recognition processing units that perform voice recognition using different recognition methods has been proposed. In this voice call registration device, the accuracy of voice recognition is improved by comprehensively evaluating the recognition results of a plurality of voice recognition processing units, and the response to the user is changed according to the accuracy of voice recognition. Thereby, a user can be provided with a comfortable use environment (for example, refer patent document 1). [0003] However, in the case of using the voice call registration device described in Patent Document 1, voice recognition is performed for all users by the same method. Th...
