Can I slow down the audio voice selected in Storyline 360?

Jun 07, 2018

I am using one of the audio voice pre-loaded in Storyline 360 and it seems they are all speaking very fast.  Is there a way to slow their speech?

Hi, everyone!

I have some great news to share. We just released another update for Storyline 360. In Update 83, we've included important fixes and new features!

One of the new features we've included:

Launch the Articulate 360 desktop app on your computer to take advantage of this update, and click the Update button next to Storyline 360. You'll find our step-by-step instructions here.

Please let me know if you need additional help!

I want to add a point. I am developing technical training in the US for world wide use. Because I have training on servers located in Germany, euro privacy laws apply. As a result company policy is not to use any live human voices so that's out.  I am getting feedback on the Articulate 360 TTS used in my modules like this on received today from our office in India.

"Slow down narrative especially in later part as it will be easier for people to follow and digest, especially those who are not well versed with use of English."

For people who speak English as a second language, most of my learners,  it is a real problem I need to solve.

Can we get some idea as to when this persistent request might be addressed?

Hi! Was this ever integrated into the SL360 updates? I want to use text-to-speech but common feedback from learners is that the voice is too fast.

I have used punctuation to slow down the speech between sentences and added silence spaces between points. Unfortunately, when a conversation is mid-point the speech is too fast.

Over a year for me as well. It’s brought up every meeting that we have, by customers, to review material that uses storyline txt-to-speech.
