Besides, the speakers reasoning which factor might affect a person impression of the arguments in a radio speech

One factor that might affect a person's impression of the arguments in a radio speech is their prior knowledge or understanding of the topic being discussed. If the listener is already familiar with the subject matter and has a well-informed perspective, they may be more critical of the arguments presented if they detect any inaccuracies or inconsistencies. On the other hand, if the listener has little knowledge or understanding of the topic, they may be more inclined to accept the arguments presented without questioning them. Other factors that could impact a person's impression include their personal biases, beliefs, and values, as well as the overall credibility and trustworthiness of the speaker. Factors such as the speaker's tone of voice, charisma, and delivery style might also influence how the arguments are perceived.
