Using memory during a speech can also affect how the orator influences the audience. When the speaker addresses the audiences relying solely on their memory, they build a certain amount of ethos within the relationship. Memoria in relation to ethos during a speech situation can be described as a certain amount trustworthiness felt between the audience, as well as a level of similarity, authority, or expertise that the orator has over the audience. Unlike ancient Greece, in today's society, it is much more acceptable for politicians and for people of authority to use aids when delivering addresses. Although it could be viewed as an aid to use notes or teleprompters, greater importance is placed on actually conveying the information to the audience in a clear and concise manner.
