Synthesis attack is similar to replay attack in that it also involves the recording of voice samples from a legitimate client. However, these samples are used to build a model of the client’s voice, which can in turn be used by a text-to-speech synthesizer to produce speech that is similar to the voice of the client. The text-to-speech synthesizer could then be controlled by an attacker, for example, by using the keyboard of a notebook computer, to produce any words or sentences that may be requested by the authentication system in the client’s voice in order to achieve false authentication.
