Which form of supporting material can provide a personal touch to a speech?

Anecdotes are a powerful form of supporting material that can add a personal touch to a speech. They consist of short, often personal stories that illustrate a point or provide context. When speakers share anecdotes, they create a connection with their audience, making complex topics more relatable and engaging. Anecdotes can evoke emotions, which helps to enhance the overall effectiveness of the speech and keep the audience interested.

In contrast, statistics, expert opinions, and graphs, while useful for providing factual evidence, often lack the personal element that anecdotes bring to a narrative. These forms of supporting material typically focus on data or authoritative voices rather than personal experiences, which may not resonate on a personal level with the audience. This personal engagement is what makes anecdotes particularly valuable in oral communication.
