Provided is a signal generation processing device that achieves audio synthesis processing or image signal generation processing capable of obtaining high-quality audio signals or image signals while maintaining the speed of audio synthesis processing or image signal generation processing. In the signal generation processing device, the first sub-model unit to the N-th sub-model unit each performs training processing for training models included in the first sub-model unit to the Nth sub-model unit using noise levels included in different noise level ranges to obtain trained models. In other words, the signal generation processing device performs processing for each sub-model unit in parallel, thus allowing for performing the training processing at high speed. Further, during prediction processing, the signal generation processing device appropriately selects the sub-model units to be used and performs processing with the selected sub-models, thus allowing for performing audio synthesis processing and image generation processing with high accuracy.

An object of the present invention is to continuously estimate the position with high accuracy while the moving body is traveling. A position estimation device is installed in a moving body, and includes a position estimation unit configured to estimate a position of a subject moving body being the moving body in which the position estimation device is installed using any of positioning means of satellite positioning using a positioning satellite or radio wave positioning using wireless communication, and a positioning means selection unit configured to switch the positioning means the position estimation unit uses for estimation of the position of the subject moving body based on a traveling environment or a peripheral environment of the subject moving body.

[Problem] With conventional technology, it is impossible to appropriately support spoken dialog that is carried out in multiple languages. [Solution] A spoken dialog device includes: a receiving unit that detects a voice section from a start point to an end point of an input speech that is spoken in any of two or more different languages, and acquires speech data corresponding to the voice section; a language identifier acquisition unit that acquires a language identifier that identifies a language in which the input speech was spoken; a speech recognition unit that generates a text resulting from speech recognition, based on the input speech and the language identifier; a dialog control unit to which a text resulting from speech recognition and a language identifier are input, and that generates a different output sentence depending on a language identifier, while maintaining dialog history even when the language identifier is different from the previous language identifier; a speech synthesizing unit that generates a speech waveform based on the output sentence and the language identifier; and a speech output unit that outputs a speech that is based on a speech waveform generated by the speech synthesizing unit. With such a spoken dialog device, it is possible to appropriately support spoken dialog that is carried out in multiple languages.

In order to solve a conventional problem that, after a series of dialog between a user and a spoken dialog device has progressed to some extent, that user or another user cannot see or recognize a previous dialog status, a cross-lingual spoken dialog system is provided wherein, in a case in which an instruction from a user terminal is received by a pairing server, dialog information stored in a storage medium is transmitted to the user terminal. Accordingly, even after a series of dialog between a user and the spoken dialog device has progressed to some extent, that user or another user can see or recognize a previous dialog status.

A ferrule is positioned on a ceramic package by a ferrule support member and is fixed between the ferrule support member and the ceramic package by an adhesive. On the side in the vicinity of one end of the ferrule, a groove is formed around the ferrule as an adherence enhancement.
