- Abstract
- There are many ways in which a person can identify a person. Biometric authentication uses a wide variety of methods, including fingerprint, voice, face, iris, the lines of the palm, and vein distribution. Of the various authentication methods, the voice authentication method is a very effective authentication method in terms of security, convenience, and economy. Because voice signals contain a lot of information, the results of differentiating personality will vary depending on how bandwidth-limited is done. In this study, the identification rate difference according to the bandwidth-limited of the voice signal was confirmed by using a sound color marker that expresses the voice signal into seven colors. As a result of the experiment, it was possible to identify the same person or others in various cases of bandwidth-limited voice signal only by comparison of sound color marker. Also, it can be seen that, even if the bandwidth is limited to various forms, all of them have individual characteristics. As a result, the sound color marker reflects the bandwidth-limited individual characteristics, so that even if bandwidth-limited, identification of the same person or other person is possible. ?
