There are a number of ways to help people with each of these common writing problems.
Speech Recognition
Speech Recognition allows you to speak into a microphone and have the computer or tablet convert your spoken words into text that can be saved into a document, for example into Microsoft Word or other programs on the computer or tablet. For someone who has trouble with spelling, or just getting his or her thoughts on paper this is very useful. It is also useful for those who have trouble with keyboarding. Dragon Naturally Speaking is the best known speech recognition program in the world for computers running Microsoft Windows, and they also make a version of their program called Dragon Dictate for Macintosh computers. Window’s computers (Vista, 7, and 8) also come with a free speech recognition program in the control panel however it is not as accurate as Dragon but works well for some peoples needs. There is a Dragon Dictation App for the iPad that also works very well and it is free. Dragon Naturally Speaking comes in a Home Version which works with Microsoft Word and a Preferred Version which costs more but works with a larger variety programs.Here is a good 2-minute video about Dragon Speech Recognition from Youtube (2 Minutes)
