Text to speech speed

Hello Guys, i think Articulate Storyline needs to improve the text to speech features, so that we are able to adjust the speed of the narrator. because all the narrators (voices), are really too fast, and in order to make it some how slower, we have to add punch of commas; which make the sound very annoying but understandable. 

It will also be great , to make the narration speed in a slider (from 1 to 10)not drop-down list (slow, medium, fast).

Just spent some time mucking around with the Storyline 360 TST and the following seems to be true. I used Salli's voice, but it looked to be the same on other voices.

It's not perfect, but something to work with. These should immediately follow text. They haven't been tested extensively:

  • Comma [,] = 1/4 sec silence (works even if not followed by a space)
  • Period [.] = 1/2 sec silence (must be followed by a space)
  • Period [.], [Return] = 3/4 sec silence
  • Period [.], [Return], [Return] = 5/8 sec silence
  • Period [.], [Return], Caret [^], Asterisk [*], Open Bracket [(], [Return] = 1 1/8 sec silence

Anyone come up with any other combinations?



Thank you for these tips. I'd l had tried the carriage returns, but not the caret, asterisk  or open bracket.

Hi SL guys, any update on this request? Beside playing trick to generate a slower audio file, what is truly needed is the possibility for the learners to modify the audio speed WHILE they watch the course. Of course the side needs are to keep the closed captions AND the screen actions synced with the new pace. Are you planning to implement this feature next?

BTW, just read it's not yet on top of your roadmap. Well, it should be, because being able to vary the speech speed is the very first question I'm getting from my learners since we went broad with our courses.
