Description

  The present invention relates to a voice recording and reproducing system and a voice recording and reproducing method.

  At call centers and offices, the contents of calls made by the customer and the operator at the other end of the call are recorded to prepare for future problems and to review the contents. The voice recording data can be voice-recognized and converted into text data, so that the computer system can search, display and print, and can be more effectively utilized as business data.

  The contents of customer inquiries received at the call center include information such as customer requests and complaints, and a wide variety of useful information that provides hints for improving products and services and improving customer satisfaction. It is included.

  Therefore, the conversation of the contents of the inquiry from the customer to the call center is made into a database in the form of voice data or text data in which the voice content is transcribed, so that the database can be shared among related departments. Create a database of inquiries to improve business and customer response.

  However, the conversation content between the customer and the operator often includes confidential information such as personal information of the customer. Therefore, if the voice of the conversation between the customer and the operator and the text in which the contents of the conversation voice between the customer and the operator are transcribed are shared as they are by the related departments, there is a possibility that the confidential information of the customer may be leaked.

  Therefore, when the voice of the conversation is recorded, it is necessary to prevent the leakage of the secret information such as the personal information of the customer. Patent Document 1 describes a system capable of preventing leakage of secret information.

  Specifically, in Patent Document 1, the voice recognition device performs voice recognition of the voice input from the call recording device, and outputs the text of the recognition result to the detection device. The keyword storage device stores in advance a keyword corresponding to the secret information and an appearance pattern of the secret information. The detection device detects the position where the keyword and the appearance pattern stored in the keyword storage device appear in the text of the recognition result input from the voice recognition device, and outputs the position information of the appearance position. The replacement device uses the position information input from the detection device to delete or substitute the voice of the corresponding part of the voice recorded by the call recording device with another voice data.

  An embodiment is a system for recording customer-operator calls in an office or call center. Call information (call start time, call end time, call identification ID, extension number, etc.) and recording information (call start time, call end time, recorded file) are managed by a database as an index for searching recorded data.

  Depending on the contents of the conversation, personal information (such as a credit number or a password number) may be included in the recorded file that has been called. If you want to provide recorded files for information sharing and education purposes to related departments, you can share them with related departments using the audio publishing function. However, it is necessary to limit the users who share the recording file in terms of information leakage. In addition, in deletion of personal information in the recording file, it is necessary to mask the audio data of the corresponding portion using a general voice processing tool.

  Here, as a technique for masking personal information in a recording file, generally, there is a method of downloading the recording file to a personal computer (PC) or the like and editing it with a voice processing tool. However, in this method, since the recording file is brought out of the system, there is a possibility of information leakage from there.

  As a technique of masking personal information during recording, there is a method of deleting personal information by detecting by keyword using voice recognition or stopping recording by operation of a telephone. However, in this method, only a masked recording file in which a part of the recording file recorded during the call is masked remains, and the original recording file in which all the contents of the call are recorded does not remain.

  In the embodiment, the original recording file is not changed, and mask editing can be performed by the user's operation, and a plurality of mask information can be defined in one recording file. In this way, it is possible to reproduce a recorded file having a different mask for each user. As described above, a plurality of pieces of mask information corresponding to the user sharing the recording file are defined, the recording file is processed based on the mask information at the time of reproduction, and the processed recording file is reproduced for each user.
