About The Open Voice Factory

The Open Voice Factory lets you make free communication grids. You can see one running here.

To make your own, you download a PowerPoint template, make some changes, and when you upload it, you’ll get a working communication grid. All for free.

The grids run on any platform, from tablets to laptops to phones, without installation or complex setup.

Everything we make is free. That’s free as in ‘don’t pay for it’ and free as in speech. All of our code is freely available on github here and anyone can change or repurpose without having to ask us first. We’re supported by the volunteers who write the code, create the templates and help out all over.

How it works

The Open Voice Factory creates grids in the Open Board Format, which is used it a lot of assistive technology. We wrote our own viewer for it, and you can click here to play around with it. You can also download the Open Board Format file to use in another system.

Create your own.

If you’d like some help getting started, you can download a simple starting template of CK12 or CK20 and look at our help files.

The Open Voice Factory is simple. There are NO usernames, NO passwords. Just upload a template and you’ll be given a special link that you can always use to get back to the communication device you created.

You can try it out right now by going to our upload page and making a start by watching our 60 second getting started video.


The Open Voice Factory relies on volunteers to do things like test, convert, spot errors, and write documentation. We want to thank all of these people who’ve already made a contribution to either this or the CommuniKate project. We really couldn’t have done it without out you.
