Communication technology is advancing rapidly. The newer computer voice recognition programmes are still very expensive but are improving quickly. Some other computerized systems may be of help but, before you think of high technology solutions, many much simpler devices and procedures may be better, including such things as:
•  picture or word charts;
•  alphabet charts where you can spell out the words that you want with your fingers or eyes;
•  agreed signals with your partner/family/friends for yes, no and other words, or
•  eye blink systems.
Your  choice  is likely to  be influenced  by your  own  skills, how comfortable you and others feel with a particular system, and the costs (financial and otherwise) that your choice may incur.
If you are buying a computer, get independent advice on which system is the most appropriate  for you. Think about the future also before you buy because computer  systems quickly become outdated! There are currently systems, portable as well as desk-top, that automatically print out your messages and translate your words into speech. Some allow you to use single key strokes, not only to create more complex messages but to control  other  facilities around  the  home.  It is not  possible to give individual advice to you here, because of the rapid changes occurring, as well as because everyone’s abilities and needs are so personal. A range of communication aids can be supplied by the statutory services depending on your circumstances, including your local education  authority, NHS Trusts, GP fund holders, and the Department  of Employment; there are also Communication Aids Centres, in addition to individual professional advice. You should ask your GP, neurologist or occupational or speech therapist for a referral to a specialist centre if possible.
