Lightwriter SL50

The new Lightwriter SL50 has been designed to be the best dedicated text-to-speech device for literate users who are unable to communicate effectively through speech.

With a Lightwriter you can participate in social interactions while at work or during leisure time, even in noisy, sunny outdoor or poorly lit environments.

Every part of the Lightwriter SL50 has been designed specifically for purpose. From the dual screens and loud clear speakers, to the user interface and word prediction - everything is focused on delivering your speech as effectively as possible. So, no more compromises, no more distractions, just clear, fast effective communication at the press of a button. Just start typing and off you go.

The Lightwriter SL50 is available in selected languages:
Finnish, Danish, English, Dutch, French, Spanish, Italian and German.



Communication is part of life, nobody should be excluded. The SL50 is designed to be efficient and is always ready to talk - just press any key and you’re ready to go. The menu is relevant and simple making it fast to use - no distracting apps or screen loading times, so you can just get on with communicating. Designed with dual screens for face-to-face engagement, meaning you can communicate naturally with eye contact, gestures and body language.


The SL50 is designed for everyday life. Whilst out and about, you can stay in touch with everyone - connect to your mobile phone using Bluetooth and make phone calls through your Lightwriter, using a combination of the synthesised speech and your own voice. Or access your phone book and send a text message easily (for Android only) to let your family know where you are. If you are meeting friends in a busy café, the loud clear outfacing speakers ensure you can still be heard, and the outfacing screen confirms what you’ve said. If you decide to sit outside it’s not a problem with an adjustable screen that will still be clear in daylight, and backlit keys should the day turn to into night.


The Lightwriter is small, portable and robust. You can take it everywhere as it is designed to withstand the bumps and knocks of everyday life. Long battery life means you can use your Lightwriter as much as you want all day every day.


You can set up your SL50 just the way you need it. It can be used in many different ways to suit your situation, even if it is constantly changing. You can choose from a selection of keyguards, and adjust key sensitivity settings to support your needs. Whether you like to have a clean, basic menu setup or if you like to get stuck into all the settings, the menu can be configured to only show what you need. Change the size of text and screen brightness, adjust volumes and sounds, choose your own voice and make it totally personal to you.

A comprehensive dictionary is pre-loaded into your SL50. Its adaptive technology will learn new words and predictions as you type and become more responsive as time goes on, making it faster to find the words you need. You can upload and download your own dictionary, blacklist words you don’t need to use, and even change the way you pronounce certain words. If you need keyboard scanning, this is also ready to go and can be set up to function the way you need it, with one or two switches. You can also use a combination of scanning and keyboard presses if your energy and dexterity changes throughout the day, or throughout the years.
