The voice conversion unit 13 outputs text data by converting the recognized voice into text. Illustration of the voice recognition dictionary is omitted. In this way, the voice conversion unit 13 converts the voice data into text data by recognizing the voice shown in the voice data.

The speech recognition dictionary is composed of an acoustic model, a language model and a pronunciation dictionary. The acoustic model is a model for discriminating the character represented by the voice by analyzing the frequency component of the sound or the time change of the sound. For example, the acoustic model quantifies the characteristics of the sound in each character of "hello". The language model is a model for evaluating whether a character string or a word string is appropriate for Japanese, and is a collection of Japanese texts and statistical processing. A pronunciation dictionary is a dictionary for associating words in a language model with an acoustic model. That is, the voice conversion unit 13 analyzes the voice of the voice data based on the acoustic model, and then constructs the word pronunciation using the pronunciation dictionary. Further, the voice conversion unit 13 evaluates the sequence of word pronunciations based on the language model. This enables the voice conversion unit 13 to perform high-precision conversion from voice data to text data.

The voice conversion unit 13 outputs text data to the character analysis unit 14. The character analysis unit 14 performs an analysis process for extracting a word corresponding to a preset management item, which is an item indicating the situation of a defect, from the text data. The character analysis unit 14 outputs the analysis result word to the analysis result storage unit 15.

FIG. 3 is a diagram for explaining analysis of text data in the defect information management system 1 according to the first embodiment. Each item of "defect classification", "defect phenomenon", "defect location" and "detailed content" is an example of preset management items. FIG. 3 shows an example of a word extracted by the character analysis unit 14 when there is a product defect that the screw is loosely tightened at some points of the adjuster.

The character analysis unit 14 learns a word corresponding to each management item in advance, and extracts the word from the text data. In FIG. 3, for example, "work defect" is a word corresponding to "defect classification". The character analysis unit 14 extracts the word corresponding to the management item from the text data, and decomposes the text data into information necessary for managing the status of the defect.

The character analysis unit 14 extracts words related to the management item by performing text mining for each management item. In the first embodiment, the character analysis unit 14 performs text mining by sentiment analysis. Not limited to this, the character analysis unit 14 may perform text mining by correspondence analysis or principal component analysis.

When the analysis result storage unit 15 acquires the analysis result from the character analysis unit 14, the analysis result is stored in the management database 12 by writing the analysis result in the defect status management list 19. As a result, the management server 3 reflects the analysis result in the defect status management list 19.

FIG. 4 is a diagram showing an example of a defect status management list 19 held by the defect information management system 1 according to the first embodiment. Each item of "date and time", "reporter", and "location of defect occurrence" is an item of defect identification information. In the defect status management list 19, information on the date and time when the defect was reported is written in the "date and time" column. The worker name is written in the "reporter" column.

In the defect status management list 19, the analysis result acquired from the character analysis unit 14 is written in each column of "defect classification", "defect phenomenon", "defect location", and "detailed content".

“Image storage destination” indicates a storage location of the management folder 18 in which image data is stored. An address, which is information indicating the storage location, is written in the "image storage destination" field. When the management folder 18 is created, the folder creation management unit 17 writes information indicating the storage location in the defect status management list 19. As a result, the management server 3 reflects the information indicating the storage location of the management folder 18 in the defect status management list 19.

In the first embodiment, the defect information management system 1 stores the voice data transmitted by using the call function of the call application 6 in the management server 3. Further, in the defect information management system 1, the mobile terminal 2 acquires image data by shooting using the shooting function, and stores the image data transmitted by the mobile terminal 2 in the management server 3. The audio data and the image data are stored in the management server 3 by different operations from each other in the mobile terminal 2. Therefore, the defect information management system 1 needs to manage the audio data and the image data in association with each other.

FIG. 5 is a diagram for explaining a process for managing audio data and image data in association with each other in the defect information management system 1 according to the first embodiment. The mobile terminal 2 transmits audio data or image data to the management server 3 at the first access for status reporting. The management server 3 adds the defect identification information obtained by analyzing the data at the first access to the created management folder 18.

The management server 3 analyzes the defect identification information for the audio data or image data received after the first access, and is received in the management folder 18 to which the same defect identification information as the analyzed defect identification information is added. Stores audio data or image data. As a result, the defect information management system 1 manages the audio data and the image data transmitted from the mobile terminal 2 in association with each other by the defect identification information.

In the above description, the management server 3 creates the management folder 18 when the first access is made, but the management folder 18 may be created after the first access.

In step S2, the defect identification information analysis unit 16 analyzes the defect identification information acquired from the input / output interface unit 11. In step S3, the folder creation management unit 17 creates a management folder 18 to which the defect identification information is added.

In step S4, the management database 12 stores the defect status information in the created management folder 18. In step S5, the voice conversion unit 13 converts the voice data stored in the management folder 18 or the voice data acquired from the input / output interface unit 11 into text data. The voice conversion unit 13 outputs text data to the character analysis unit 14.

In step S6, the character analysis unit 14 performs analysis processing of the text data and outputs the analysis result to the analysis result storage unit 15. In step S7, the analysis result storage unit 15 stores the analysis result in the management database 12 by writing the analysis result in the defect status management list 19. As a result, the defect information management system 1 ends the operation according to the procedure shown in FIG.

According to the first embodiment, the defect information management system 1 makes it possible for the management server 3 to acquire defect status information including voice data, so that it is possible to reduce the time and effort required to report the status of the manufacturing site. In addition, the defect information management system 1 converts voice data into text data, and performs analysis processing for extracting words corresponding to management items from the text data. The defect information management system 1 stores the analysis result in the defect status management list 19. As a result, the defect information management system 1 can easily analyze and manage information about defects at the manufacturing site.

Further, according to the first embodiment, it is expected that the number of reports on the situation at the manufacturing site will increase by reducing the burden of the situation report by the worker 4. The defect information management system 1 can acquire a large amount of information about the situation at the manufacturing site, which enables highly accurate analysis of defects. In addition, the defect information management system 1 can facilitate analysis of defects.
