This paper discusses the results of research work performed to change the speaker’s voice profile and edit the voice message in an unauthorized way. The results of conducted research work confirm that the intentional voice modeling in telephone lines can result in gaining or losing trust in the subscriber, thus gaining or losing access to confidential messages in an unauthorized way. The analysis of security regarding the trust in voice identity leads to developing new, unconventional protection methods: using hidden identification in the form of watermarking tokens and the tests of susceptibility to impersonation of the key corporation personnel and government officials.
