Narrators in back-to-school ads often speak faster than normal for several reasons:
1. Time constraints: Back-to-school ads often have to fit a lot of information into a short amount of time. Speaking quickly allows the narrator to convey more information in a shorter period of time.
2. Attention-grabbing: Fast-talking narrators can be more attention-grabbing than slow-talking ones. By speaking quickly and energetically, the narrator can engage the audience and hold their attention.
3. Conveying excitement: Back-to-school ads are often designed to create a sense of excitement and anticipation for the upcoming school year. Speaking quickly can convey a sense of energy and excitement, which can be contagious for the viewers.
4. Memorable: When a narrator speaks quickly, it can make the ad more memorable for viewers. People tend to remember information that is presented in an unusual or distinctive way, and a fast-talking narrator can make the ad stand out in the viewer's mind.
Overall, fast-talking narrators in back-to-school ads are a common tactic used to make the ad more engaging, memorable, and to fit more information into a shorter period of time. However, it is important for advertisers to strike a balance between speaking quickly and being comprehensible so that viewers can still understand and retain the information being presented.
