Answer:
Microphone-free delivery, Casual presentation tools, and Minimal or no visual aids are the technologies.
Step-by-step explanation:
Microphone-free delivery: In a small setting, where the audience is close and intimate, speaking without a microphone can create a more personal and informal atmosphere. However, for larger audiences, it would be challenging for everyone to hear the speaker clearly without amplification.
Casual presentation tools: Informal speeches to smaller audiences may benefit from the use of casual or interactive presentation tools, such as whiteboards, flip charts, or handheld props. These can facilitate engagement and create a more conversational setting. However, in larger settings, such tools may not be visible or easily accessible to everyone, diminishing their effectiveness.
Minimal or no visual aids: In informal settings, where the focus is on direct interaction and conversation, the use of minimal or no visual aids may be appropriate. This allows for a more spontaneous and flexible presentation. However, in larger audiences, visual aids become crucial for ensuring that all participants can follow along and understand the speaker's points.
