Final answer:
Formal language and meticulous word choice impact a speaker's tone by potentially creating a superior, serious, or persuasive tone, each influencing how the audience perceives and reacts to the message conveyed.
Step-by-step explanation:
The effect of formal language and word choice on a speaker's tone can be quite significant. Formal language can convey a sense of professionalism or seriousness to the audience, affecting the perceived credibility and authority of the speaker. This can sometimes create a tone that is seen as superior if the language seems detached or overly formal. On the other hand, the right word choice can also help establish a serious tone when discussing important subjects, indicating the matter should be taken with gravity. Moreover, strategic word choice is essential for creating a persuasive tone, as it can be used to appeal to the audience's emotions and logic, helping to convincingly present an argument or narrative.
