Answer:
True.
Step-by-step explanation:
Presentation (speech making) can be defined as an act of talking or speaking formally to an audience in order to explain an idea, piece of work, project, and product with the aid of multimedia resources or samples.
Basically, any speaker who wish to create an effective presentation should endeavor to interact frequently with the audience by holding a conversation.
An interference can be defined as any object, barrier or gesture that affects proper communication or dissemination of informations from the speaker to the recipient or listener. An interference in public speaking is classified into three (3) main categories and these are;
1. Internal interference: these are usually caused as a result of fear, stress or nervousness by the speaker.
2. External interference: these are auditory or visual barriers occurring outside the control of the speaker or listener. Examples are loud sound system, buzzing horns of a car, and noises generally.
3. Speaker-generated interference: these are caused by the speaker and they include mental and physiological obstacles.
Properly channeling your nervousness can boost speech performance such as endeavoring not to speak too quickly, anxiously or harshly.
