Description of the Related Art In general, a car navigation system is equipped with a ROM such as a CD storing audio information covering all over the country in Japan as a storage medium. For this reason, the voice information service can be performed anywhere in the whole country by performing the voice reproduction process according to the situation at the time of the route guidance of the vehicle using the voice information stored in the storage medium at the time of the route guidance of the vehicle. This voice information service generally provides voice guidance such as straight ahead, left turn, right turn, and the like and guidance for travel guidance when a vehicle traveling on a guided travel route is moving toward the next node (for example, an intersection). This is audio information such as how a building to be represented appears. For this reason, the driver can have a sense of security about the route guidance, and can drive the vehicle while looking closely at the front of the vehicle without carefully watching the navigation display on the display. Further, it is advantageous from the following viewpoints. (1) It is possible to prevent the vehicle from deviating from the guidance traveling route. (2) The vehicle can run safely. (3) The focus adjustment for aligning the host vehicle with the guidance traveling path is facilitated, and the response time required for the adjustment can be reduced.

M must have a sufficiently large memory capacity. For example, the ratio of voice guidance in a storage medium is much larger than that of map information. In one example, it is necessary to use one CD for map information and nine CDs for voice information. There is. For this reason, the space occupied by the storage medium in this kind of car navigation device becomes large, and there is a problem that it is not possible to cope with a demand for further downsizing the car navigation device. In addition, there is a problem in that the car navigation device cannot use the voice information service unless all of the voice information covering all over the country in Japan is stored in advance in the storage medium when the vehicle is shipped. Conventionally, the voice information service has been used exclusively for a car navigation device. However, there has been a problem that it cannot be used for other purposes.
For example, it provides general audio information services such as weather forecasts that are not directly related to vehicle driving, restaurant menus on the way to the destination, and stories told to children. The conventional car navigation system could not cope with the demand for the car navigation system.

サービスの質の向上に貢献できる。According to a first aspect of the present invention, there is provided a voice information service apparatus for connecting a voice database to a voice database via a network such as the Internet. An information processing unit capable of downloading audio information from an audio database via a storage unit, wherein the information processing unit stores the downloaded audio information and a vehicle using the audio information stored in the storage unit. A sound reproducing unit that executes a sound reproducing process for a sound information service in response to a passenger request. According to the first aspect of the present invention, a voice information service device according to the present invention captures voice information from a voice database by connecting to a voice database via a network by an interface unit, and converts the captured voice information into information. Downloaded by the processing unit and stored in the storage unit,
Using the stored audio information, the audio reproduction unit executes the audio reproduction process, and performs the audio information service using the obtained audio. According to this configuration, for example, in the case of providing a voice information service according to the situation at the time of vehicle route guidance in Japan, instead of storing all voice information covering all over the country in Japan in a ROM such as a CD, This can be dealt with by downloading audio information from an audio database as needed and storing it in a storage unit. Therefore, for example, if the car navigation device has the structure to which the present invention is applied, the memory capacity required for providing the voice information service can be significantly reduced, and the demand for further miniaturization can be dealt with, and the cost can be reduced. Can be achieved. Furthermore, since the voice information service can be used without storing the voice information in the storage medium in advance when the vehicle is shipped, the trouble of shipping the vehicle can be saved, and the information can be easily updated. Become. In addition, since a voice database that can store a large amount of voice information by compressing it etc. will be used as an information source, it will not be directly related to the running of the vehicle. General audio information such as a restaurant menu existing on the way or a story to be told to a child can be fetched from an audio database as needed, thereby contributing to an improvement in the quality of audio information services.

となる。The voice reproducing unit 5 selects a voice information service relating to the running of the vehicle and a general voice information service not directly related to the running of the vehicle in response to a request from the vehicle occupant. Since the selected voice information service can be provided after the processing, it is possible to cope with a case where the voice information service relating to the traveling of the vehicle is particularly required at the time of route guidance and a case where the voice information service relating to the traveling of the vehicle is not required. In the former case, in addition to the voice information service for each part of the route guidance on the map, it covers road congestion conditions and tolls for toll facilities for vehicles that are likely to be used by vehicle occupants. Since the voice reproduction process for providing the voice information service is performed, when the vehicle traveling on the guidance traveling route is moving toward, for example, an intersection in front of Kameido Station, the voice notification is first "500 m ahead, in front of Kameido Station. Is to the left, and then turn left at Kameido station square intersection,
"We will go straight down Shimogamibashi Higashizume." During this straight line, it will be "One kilometer ahead, Keiyo Road Funabashi tollgate", followed by "The fee is 1500 yen". As a result, the driver can immediately respond to the toll facility, and the road congestion status and the like on the guidance driving route are appropriately sounded, so that the driver can visually recognize the response to selecting the detour route. You can get it instantly without relying too much.
In the latter case, general audio information such as weather forecasts that are not directly related to the driving of the vehicle, menus of restaurants existing on the way to the destination, and stories told to children. Service available. In particular, if the selection of the detailed menu is accepted and the audio reproduction processing for providing the audio information service for the corresponding detailed menu is executed, the weather information of a plurality of regions not directly related to the driving of the vehicle can be obtained. Forecasts, menus of various restaurants existing on the way to the destination, and multiple stories to be told to children can be individually selected by menu selection, so the general voice information service has been enhanced. It will be.
