Final answer:
The claim that practiced speeches are less natural is false. Repeated practice enhances fluency, reduces verbal fillers, and allows for better control of gestures and expressions, leading to a more natural and effective presentation. Option number b is correct.
Step-by-step explanation:
The statement "Practicing your speech repeatedly will worsen your presentation and make it less natural" is false. In fact, repeatedly practicing your speech is one of the most effective ways to improve fluency, which refers to the flow of speech. Fluency is crucial as it is not about the speed of talking, but about how smooth and coherent your speech delivery is. Proper practice helps you avoid awkward pauses, maintain your train of thought, and also keep fluency glitches such as verbal fillers—like 'um', 'ah', and 'like'—to a minimum. These verbal fillers can detract from your speech's effectiveness and potentially your credibility.
Beyond fluency, gesturing and facial expressions are important aspects of your presentation. They can significantly enhance your message by demonstrating emotion, emphasizing points, and engaging the audience. Effective use of these physical delivery variables can make your presentation more dynamic and engaging, whereas excessive or inappropriate gestures might be distracting or convey mixed messages. Therefore, practicing your speech and being self-aware are key to mastering both vocal and physical delivery, making your presentation more natural and impactful.
