Giving a voice to people

Predictable logo


Who’s it for?

Predictable is designed for people who are literate but have lost the ability to speak. Possibly due to cerebral palsy, motor neurone disease, laryngectomy, stroke, apraxia or brain injury.

What do they do?

Start typing on Predictable and it will predict what you want to say and read out the sentence for you - it gives a voice to people who don’t have one. Predictable is a multi-award winning app and the market leader in its category. It’s also available in 10 different languages!

Head Tracking

Use your head to control Predictable

Predictable now features head tracking which allows you to control the app with your head movements. It is easy and quick to set up and simple to use.

Advanced Word Prediction

Type faster with advanced word prediction

Predictable learns how you speak and gets quicker and more accurate in predicting your sentences. These predictions are shown in a bubble above your text. They quickly become personalised based on the things you say, making constructing sentences faster and easier.

It also has an autocomplete function that lets you add words rather than typing them.

Use your own voice

Record sentences to keep a part of your own voice

With Predictable you can record yourself speaking the things you say a lot or the things that are really important to you, and save them in your phrase bank.

Predictable also enables you to create a synthetic voice that sounds like you, with just a laptop and microphone. This comes via the ModelTalker System, developed by Nemours Speech Research Laboratory.

Quick phrase selection

Keep your favourite phrases within easy reach

Predictable makes it easy to group phrases into categories. Full sentences, paragraphs or longer can be stored and accessed in just a few taps, and if you've banked any messages then the audio files can be saved as a phrase.

The new layout in Predictable 5 enables you to set up phrases to be displayed in either a list or a grid format, depending on your personal preference; and we've added a phrase search button, which gives you extra quick access to your saved phrases and your recent speech history.

Avoid interruptions

Prepared messages can be automatically played to hold the floor

Predictable can automatically speak prepared sentences while you type your message. This lets people know you're speaking and helps prevent interruptions. You can save as many of these messages as you like and Predictable will rotate through them so that you don’t repeat yourself. They can also be played at the touch of a button.

Cloud Backup

Save your account setting in the cloud

You will never accidently lose your account settings as they are all backed up to the cloud. This also means that you can use your login details to quickly access your personalised account from any platform (including Android, iOS and Windows).

5 Keyboards

Choose the keyboard that suits you best

5 inbuilt keyboards are available, including one that splits the alphabet up into 10 keys, providing you with a large target area. As well as this, a huge range of external third party keyboards can be used including the popular SwiftKey keyboard and Phonics keyboard.

Use without a keyboard

Type words either with a switch or by touching anywhere on the screen

You don’t need to be able to use a keyboard to type out each word. Predictable can be controlled by a switch that enables you to easily scroll through all of the options on screen. Alternatively, you can also tap anywhere on the tablet screen when the section you want to click on is highlighted.

"Predictable®’s advanced word prediction was exactly the type of feature we were looking for to increase Joe’s speed with communicating."




"A stroke means a big change in every part of life. This was also the case for Julia: talking, moving & nothing was easy anymore, a lot of things she had to learn again. Predictable allowed her to communicate through this tough time."




"Gordon got in contact with the Therapy Box team when he was diagnosed with ALS. He tried Predictable and thereafter decided to purchase the app. He wrote the poem to the team to show his thanks."
