Slideshows are, more often than not, accompanied by a great deal of speaking, so it’s no surprise that you might sometimes need to pause the audio during the presentation. PowerPoint allows you to do so with the click of a button.
Unless your presentation is intended for viewing without a speaker (like a slideshow full of images for an audience to observe during a wedding), there will likely be a point when you need to pause the audio to answer questions, speak longer on a subject than intended, and so on. Luckily, pausing audio is extremely simple.
