Some options for controlling pauses in Text-To-Speech (TTS)
Jul 10, 2021
There was an article posted a while back that talked about how to add pauses in Storyline's text-to-speech. It mentioned adding punctuation, but it missed the option to add line breaks, and didn't cover the difference in pauses caused by different characters.
What I found was that commas add the shortest pause. Periods are a little longer. Line breaks are almost double the pause of a comma. In case you're wondering, you can't add pause characters together to lengthen the pauses but I'd like to add that as a feature request.
Here's a test you can run to try it for yourself:
Cut the text below between the ----- markers and paste it into the TTS editor. Play the audio by previewing the slide. You will definitely hear the difference.
Do not edit the text unless your cut-and-paste removes the line breaks. Make sure there are two line breaks per number in the final test. Technically looking like this:
With no pause characters, I sound like this: one two three four five
With commas as pause characters, I sound like this: one, two, three, four, five,
With periods as pause characters, I sound like this: one. two. three. four. five.
With line breaks as pause characters, I sound like this:
Hope this takes some of the mystery out of TTS. I've also included a .story file for convenience, if that helps.
