Adding more computer voices to Text-to-Speech

Sep 07, 2018


I'd like to know if there's a way to add custom computer voices to A360 text-to speech, besides what is already available.

I'm looking for more natural voices and I've found a few I'd like to use.

Thanks for your help, cheers

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!

I would consider adding the functionality to import other voices instead. There are so many companies working on audio processing, it's not worth locking them out of your system and waste your resources on creating voices customers can buy from a 3rd party vendor.
I mean it as sincere recommendation.

Dear Anthony,

I don't mean to be mistrustful, but your question does not sound much like a real question, but I feel like you're challenging my statement.
If my feeling is wrong, I will be happy to share with you some details of my implementation plan; but if I'm right, I hope you'll understand if I don't reply to your inquiry.

Hi, Simone! I sincerely was interested in finding out the voices that you had found that were more human like. While I do find the voices included with Storyline better than some I’ve found, I have searched for others without much success. The Google Wavenet Voices are pretty good, but there is not an easy way to integrate the API with Storyline. My question was motivated by wanting to find out a potential source for better voices.

Hi Anthony,

I see, so please accept my apologies for getting your question wrong.
On my side, the feedback I have about the A360 embedded voices is not very enthusiastic; I admit there are a couple of good voices (I'm still using the free trial, maybe the full version has more), but still the audience's feedback says they sound artificial.
So I'm working on 2 possible solutions: 1) find some more natural computer voices and 2) creating a computer voice out of one of our trainers' real voice (some companies claim they can do it);
but either solution is pointless if I cannot import the new voices in A360; that's the reason for my question to this forum.

Hi PS,

This feature has not been added to the built-in functionality of the software at this time.

Here is the feature for text-to-speech that is included with Storyline 360:

Converting Text to Speech

You are welcome to share your thoughts and use-case with our team directly here.

I wanted to share some information about how we manage these feature requests as that may be helpful.

As my team are heavy users of Storyline - we would really appreciate having more voice choices as well as more human sounding choices presented. If that isn't possible, the ability to import other voices from other sources is most welcome. Given the digital age, the text to speech functionality is one of the largest selling points for my team. Thank you for your consideration.

Hello Paul,

I appreciate you sharing the thoughts of your reviewers!

We're currently monitoring requests for additional editing options with the text-to-speech feature, including humanizing the voices, and I've added your comments to the report. Here's a look into our process:

You're in the right place to hear any new news now that you're subscribed to this thread!

Yeah, this is a hard thing to create in a full elearning tool. Most of the high quality, natural voices are standalone options, as that is their focus. We use Amazon Polly (neural setting) for our TTS. I haven't used TextAloud in a while, but remember those being very high quality voices for the price. And while TTS in SL360 is a great feature, it's not one I rely on.

Dear A360 support team,

Too much talking and no progresses.
Like many requests, this about enhancing the text-to-speech features (more voices, better quality, possibility to vary the speech speed,...) is being a lot discussed and analyzed, but no improvements so far. I've posted my first comment about better voices 2 years ago and this is still being discussed.
What your users need is known as "a little less conversation, a little more action"

I'm interested in this as well. Importing TTS voices would be huge.

My boss is willing to pay $5/month to get a more natural sounding voiceover for our courses. He is also aware that I have to download/import the audio files and manually create the subtitles-- and it is still more important that the voice doesn't sound robotic.

I think this is going to be an ongoing problem as we all learn online post-pandemic.

Stacey I actually discovered that using the voice generator feature with articulate, even if the voices were more natural, it’s not worth it. Because for pronunciations you have to change the way words are spelled, but that also changes the closed captioning. It is A huge hassle to adjust those back-and-forth. It’s easier just to use a third-party tool for the voiceover and the automated captions in articulate. I use speechelo, it’s a one time fee of $29, and the main voice Joey is very natural!

Hello, Everyone!  

I'm happy to share that we have released a new update for Storyline 360 (v3.80.30988.0.).

In this update, we included an enhancement for:

  • Support for NTTS or Neural Voices

Please update to the latest version of Storyline 360 to see this improvement. Here's how:

Update Authoring Apps

If you have any questions, please let us know in this thread or privately in a support case.

Have a great day!

While this is a good step forward I am not convinced I can use it yet.

There are no options to customise pace, intonation, inflection, or build up a custom dictionary for business or industry unique/specific words.

Using those customisations in Azure Neural Voices generates an even better "real life" audio at the moment.
