Further, in each of the following embodiments, the same parts are designated by the same reference numerals, and duplicate explanations are omitted.

[1. Information processing method]
First, the information processing method performed by the information processing apparatus 1 according to the embodiment will be described. FIG. 1 is an explanatory diagram showing an example of an information processing method according to an embodiment.

First, the information processing method performed by the information processing apparatus 1 according to the embodiment will be described. FIG. 1 is an explanatory diagram showing an example of an information processing method according to an embodiment. Here, an information processing method performed when the voice data of the vehicle C1 acquired by using the user terminal 2 is transmitted to the information processing apparatus 1 via the wireless communication network N will be described.

The information processing device 1 is an information processing device such as a server that transmits / receives various information to / from the user terminal 2 via a network N (see FIG. 2) such as the Internet.

The vehicle C1 is a vehicle such as a car or a motorcycle driven by a user. The vehicle C1 has a plurality of sources that generate sounds peculiar to each vehicle, such as an engine, left and right doors, a back hatch, an air conditioner, and a muffler.

Then, the information processing apparatus 1 acquires the measurement data of the sound generated from the vehicle C1 by using the user terminal 2 or the like to which the microphone 3 is connected (step S1).

In the example of FIG. 1, the case where the microphone 3 is connected to the user terminal 2 and the sound generated from the vehicle C1 is measured is shown, but the embodiment is not limited to such an example. For example, the sound generated from the vehicle C1 may be measured using the built-in microphone of the user terminal 2. Further, the sound generated from the vehicle C1 may be measured by using a measuring device other than the user terminal 2.

Next, the information processing apparatus 1 extracts a sound component for each source from the measurement data of the sound generated from the vehicle C1 (step S2). For example, the information processing apparatus 1 uses the sound measurement data of the vehicle C1 to obtain the engine sound component, the left door sound component, the right door sound component, the back hatch sound component, the air conditioner sound component, and the muffler sound. Extract sound components for each source, such as components.

For example, the information processing apparatus 1 extracts the sound component for each source by separating the sound source from the measurement data of the sound generated from the vehicle C1 by using the existing sound source separation technology such as independent component analysis. Can be done.

In steps S1 and S2, the sound components of each source may be extracted by separating the combined sounds from a plurality of sources into sound sources, or the sounds from only individual sources may be extracted. May be extracted as it is to extract the sound component of the source.

In the latter case, "Register the engine starter sound", "Register the opening / closing sound of the right door", "Register the air conditioning operation sound of the air conditioner", and "Back hatch" in the user terminal 2 etc. By executing the guidance such as "Please register the piston slide sound of", the information processing apparatus 1 can appropriately acquire the sound from each source.

Next, the information processing apparatus 1 identifies the vehicle C1 as a unique vehicle C2 (not shown) based on the extracted sound components for each source (step S3). For example, the information processing apparatus 1 allows the vehicle C1 to compare the sound component data for each source registered in the vehicle database 121 (see FIG. 3), which will be described later, with the extracted sound component for each source. Among the vehicles corresponding to the vehicle ID registered in the vehicle database 121, it is specified that the vehicle is a unique vehicle C2.

For example, even if the vehicle type is the same, the sound component of the source is often different for each unique vehicle C2. For example, when the left and right doors are slide doors that automatically open and close, the opening / closing time of the slide doors and the driving sound of the drive motor often differ for each vehicle. Further, even in the same vehicle model, the type of the motor that drives the radiator of the engine and the fan of the air conditioner is often different, and in this case, the sound components generated from the engine and the air conditioner are different.

In this way, in the embodiment, the sound components of different sources for each vehicle are extracted as the characteristics that each vehicle has, and by combining the extracted characteristics, "this one is in the same vehicle model". Thus, the vehicle C1 can be specified as one unique vehicle C2.

Next, the information processing apparatus 1 determines the state of the source by comparing the sound component data for each source in the identified unique vehicle C2 with the sound component for each source extracted from the measurement data. Detect (step S4).

For example, if there is a difference between the sound component data for each source in the specified unique vehicle C2 and the sound component for each source extracted from the measurement data, the information processing apparatus 1 has different sound components. It is estimated that the state is different from the time when the source is registered in the vehicle database 121.

Then, the information processing apparatus 1 compares the current sound components of the sources having different sound components with the sound component data of the parts registered in the component database 122 (see FIG. 4) described later. Then, when the current sound component of the source and the normal sound component data of the component registered in the component database 122 match, the information processing apparatus 1 replaces the component of the corresponding source with another component. It can be detected that it has been done.

Further, when the current sound component of the source and the sound component data at the time of abnormality in the component registered in the component database 122 match, the information processing apparatus 1 has a problem with the component of the corresponding source. Can be detected.

Next, the information processing device 1 outputs the specified unique vehicle C2 information to the user terminal 2 or the like (step S5). For example, the information processing device 1 is stored in the vehicle database 121 such as "Vehicle C1 is a vehicle type X (model is Y) registered in 20XX years, and the previous owner is Mr. Z" in the user terminal 2. Various information of the specified unique vehicle C2 can be displayed based on the vehicle history data.

Further, the information processing apparatus 1 can output the information regarding the detected source state to the user terminal 2 or the like together with the information of the specified unique vehicle C2. For example, in the information processing device 1, parts are replaced from the unique vehicle C2 in which the vehicle C1 is specified, such as "The motor of the right sliding door of the vehicle C1 is replaced" in the user terminal 2. Can be displayed.

Further, the information processing apparatus 1 can display to the user terminal 2 that a component has a defect in the vehicle C1 such as "The vehicle C1 has a defect in the radiator fan motor." ..

As described above, in the embodiment, the vehicle C1 can be specified as a unique vehicle C2 based on the sound generated by the vehicle C1. As a result, the user can know the vehicle history of the vehicle C1 so far. Therefore, according to the embodiment, effective services are provided when the service is provided based on the vehicle history of the vehicle C1 in the automobile insurance service, the used car buying and selling service, the vehicle inspection service, the crime prevention service, and the like. can do.

For example, in the embodiment, since it is possible to detect that the parts have been replaced, it is possible to easily know that the vehicle C1 has a repair history in the used car trading service. Therefore, according to the embodiment, the price of the vehicle C1 can be determined based on the repair history.

Further, in the embodiment, since it is possible to easily know that there is a defect in the component of the vehicle C1 in the vehicle inspection service, it is possible to carry out the inspection and maintenance of the vehicle C1 based on the defect information.
