Final answer:
Speeches often have an interactive approach, utilizing the first person for personal connection, simple sentences in the active voice for emphasis, and rhetorical devices like repetition and parallelism for impact.
Step-by-step explanation:
One quality you're more likely to find in a speech than in a piece of writing is an interactive approach. In contrast to written pieces, speeches often employ the use of the first person, notably the pronoun 'I', to forge a personal connection between the speaker and the audience. Furthermore, speakers typically utilize simple, declarative sentences in the active voice for clarity and emphasis, keeping the audience's attention focused on their key ideas. To enhance the impact and retention of their message, speakers also incorporate rhetorical devices such as repetition and parallelism. These elements combined make the speech a dynamic and engaging medium of communication that directly addresses and involves the listeners.
