Not just a smooth talker!
In one small package, this Lightwriter SL40 Standard is an exciting new text to speech aid which helps the user to communicate widely. The SL40 has many new and improved features and benefits over the older SL35.
Features and Benefits
- User-friendly, intuitive interface – Easy to use in all functions
- Out-facing daylight-readable display – Encourages conversational interaction in all settings
- NaturalSelection prediction – Faster communication
Your Lightwriter will automatically remember the words and phrases you type and how you use them. As you begin to communicate it will predict what you are most likely to enter next, and will display several options on screen to make conversation and typing quicker and easier. - High-quality Acapela voices – Improved intelligibility with intonation
The SL40 is available with US and UK High Quality Acapela Speech engines.
Listen to samples of Acapela Text-to-Speech voices (MP3):
- US English Female voice (longer sample 39 sec)
- US English Male voice (longer sample 38 sec)
- UK English Female voice (longer sample 22 sec)
- UK English Male voice (longer sample 22 sec)
Please note: Computer simulations of this speech can differ from production by a Lightwriter due to speaker and sound card differences. We strongly recommend that you trial an SL40 before purchasing it so that you can determine whether the speech synthesis meets your needs. - US English Female voice (longer sample 39 sec)
- Trainable Infra-Red Remote (environmental control) – Extending the world of AAC to control basic IR controlled devices in the home
The SL40 has an Infra-Red transmitter built-in which uses infrared to operate different devices around the home, for example appliances (such as televisions and stereos), toys, and some home control systems. Please note that there are some exceptions which will not work with the SL40. - Adjustable keyboard – Suitable for a wide range of users
There are many ways in which you can adapt the SL40 keyboard to suit individual needs.- Changing the Keyguard
Each Lightwriter SL40 is shipped with 3 changeable keyguards, which provide optional barriers of varying depths around the edges of the keys. This can help users to improve their typing accuracy. - Keyboard Layout
The SL40 keyboard setup can be changed to either QWERTY or ABC layouts, depending on user preference. - Key Settings
The time a key must be pressed for to register and the minimum time between pressing keys can both be adjusted in milliseconds. These will again help each individual to improve their typing accuracy.
