Appealing to an audience: Speech rate

Let's start with rhythm and speech rate, since these are very fundamental qualities that we change a lot as we move through different contexts. This chart shows your vowel duration in the three contexts, which is a quick and easy way to calculate how fast you're talking. The longer each sound is, the more time you are taking to say it, so the slower you are talking.

We might also look at the variability of vowel duration, which we can see in how spread out the shapes above are. This variability tells us how much your speed changes over time. Often changes in speed are heard as more energetic or dynamic. Here is a graph over time of the vowel duration in the different guises, which shows when in time each stressed vowel started (on the x axis), and how long it was (on the y axis). Words that are especially high up are those you emphasized by making their stressed vowels longer. You can also see if you were faster overall in one version than the other, by seeing when the last words for each fall on the x-axis time scale.
