One of the features of an excellent presentation is the deliberate way the expression and effect of the speaker’s various roles are used. In presentation situations, the audience often expects the speaker to play the role of the expert, whose proficiency in the field is expressed through the presentation. Body language and a clear, matter-of-fact voice indicate that it’s an expert who is speaking. The effect is consequently factually convincing – but can get monotonous and bore listeners.
If the speaker’s aim is to inspire and impress their audience, this role will not suffice, and they will have to expand their repertoire to include other roles, such as that of a storyteller who makes specific contact with their audience, or a host who welcomes their guests and invites them to listen and reflect.
The role repertoire is applied based on the public-speaking structure in which content-based objectives are translated into presentation phases. This structuring is aided by a “stage-direction plan”.
