Abstract: With the development of technology related to the 4th Industrial Revolution such as smart phone and internet of the things, more convenient financial services with biometric authentication are emerging one after another. Voice authentication is cheaper and easier to introduce than other biometrics authentication methods because it can provide the biometrics authentication function with only the microphone installed in the smart phone. Voice authentication is a very good authentication method because it is possible to apply the speaker presentation method such as sentence presentation in terms of security. Especially, since, it is very difficult to restore human voice to a common speaker, speech recognition is a highly secure biometric authentication method. In this study, we used sound color marker that express intuitively the voice components to see, if it is possible to distinguish between real voice and recorded voice. As a result of the experiment in Chapter 3, we could distinguish the real voice from the recorded voice by analyzing the similarity of the sound color marking and it was confirmed that the voice is very secure from the recorded voice and the processed voice.
