In the area of adaptive software the linux arternatives are not very strong and convincing.
Write type looks like a promising application though.
It combines auditive support and wordprediction when typing and is in this way very useful for visually impaired or dyslectic people.
Lets hope it will take off and develop well
More info: WriteType is an application designed specifically for students who have difficulty typing. As you type, WriteType will offer suggestions for words. It also has TTS (text-to-speech) abilities to read text back to the author. WriteType is Free Software available under the GPL. It has only undergone small-scale field testing so far, and should therefore be considered beta.
How about internationalizing the app by adding the option to change dictionaries (and voice)?
It would just require different word lists. As it is right now, TTS (via eSpeak), spellcheck, and the interface can be easily internationalized. In fact, there is a (currently useless) option in the config file to specify the language. Word completion would would take only a little bit of code, but would require a list of words in the desired language. If you (or anyone) is interested in submitting a translation, I would be more than happy to fully make translations available.
Tried to isntall this in Arch and wnet well with sudo python2 setup.py install
But when running it got an error; aspell-en was not installed.
To use a different locale, word prediction list interface and espeak voice, use writetype -l nl_NL
