New Neural Text to Speech Voices from Amazon Polly
Storyline 360 uses standard voices from Amazon Polly for it's text to speech functionality. I imagine they use their API for this. This has been great for prototyping sides and getting the timing ri...
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 enhanced feature we’ve included:
Unlock new possibilities for text-to-speech audio. Use speech synthesis markup language (SSML) to adjust the speaking rate, modify pronunciation, emphasize words, add pauses, and more.
To take advantage of this update, launch the Articulate 360 desktop app on your computer, and click the Update button next to Storyline 360. You'll find our step-by-step instructions here!
We spends thousands of dollars each year on professional narrators for our major elearning projects. Our clients like the results so using professionals is well worth our investment. However, for smaller learning activities, using professional narrators is not practical nor cost-effective.
So I was excited to discover neural voices. Although still not perfect, these voices are now good enough for use in some projects. One of our current projects is targeted at learners for whom English is not their first language. Research we did indicates that these learners prefer to learn by "listening" rather than by "reading. So as a result, I am using neural voices to narrate some of the lessons.
Here is a sample micro-learning lesson that we built using SL3 and neural voices.
Since I use StoryLine 3 (and not 360), the text-to-speech feature is not currently available to us. Fortunately, I was able to find a very affordable cloud-based service that allows me to easily create narration using a variety of neural and other voices. Once the conversion is done, I simply download them for insertion into StoryLine and other programs.
For other StoryLine 3 users who may be interested in trying out this service, you can find out more information here. (I am not a big fan of all of the hype and sales approach at this website / vendor. However, I have subscribed to the service and the bottom line is that is works!)
I hope that this information may be useful with your elearning projects. Thanks.

UPDATE: I just discovered that I can further improve the quality of the neural voice output by running the audio file through a program called Auphonic Leveler. I have used this software for years with my narrations. It does a great job in "leveling" the audio volume and cleaning up the noise. It does involve an extra step, but I believe it is well worth the effort.
