Yes , I've looked into that possibility (using phrases).

Humans remember a lot more than that when learning any language.

What I didn't do was to explain how the input device works and maybe
that is why you think you'll have to remember numbers. The Idea is
to have a glove with 12 contacts, 3 in each finger, and a common the
thumb, then the words are permutations of 4 "contact" lenth. I made
the first prototype with alumine paper on a glove, but I am planning
(tomorrow) to get conductive polycarbonate gome to make better more
flexible glove. BTW, I found how to make 16 contact by putting contacts 
on the nail side of the finger as well then the number of possible
permutations are 65,535.

1. Imputing full lenth words using a keyboard will never be fast
enough for real time speaking (combinations of 4 finger tips
contacts are really fast) With a couple of minutes of practice , two
deaf people at a rehabilitation center were quickly getting a couple
of phrases ready, and they looked very exited BTW.

2. The device is not only intended for people with speaking
disabilities but also for people with very limited mobility,
an standard keyboard will require your both hands.

3. using less keys for writing is already proven to be faster than
an standard keyboard as you can see in "taquigrafia" (sorry only
know the word in Spanish), is the typewriters they use in court that
only has 14 keys.

4. Using a glove will give you the freedom to use your hands while
the pda can be into a pocket.

The SL5500 (can only get it used) cost between 7,000 and 10,000 yen
in sofmap mobiles in Akiba. A database of 65,000 words was 11MB
filesize using sqlite. I made a test with an existing dictionary and
a couple of randomly generated fields. ( needs to make more tests to
find out if the SL5500 can handle festival (CMUflite), sqlite and python on
real-time, but I am very convinced it will.
  

Back to the "remember 20,000": there is a big difference between
remembering numbers and moving your fingers to convert thoughts into
words, the motor-memory is a very efficient system that does not
required the same type of memory than remember telephonic numbers ,
much like the way a pianist can play a song by hart without having
to remember the exact combinations of keys that are required
(explained by a doctor of the rehabilitation center). something here 
http://www.thebrain.mcgill.ca/flash/i/i_07/i_07_p/i_07_p_tra/i_07_p_tra.htm. 

Some studies also shown that motor-memory when used for communication
porpoise will make your brain storage and read from a different
part of of the brain also you'll skip certain processes that are necessary 
the remembering other type of things. , like in sign language:
http://faculty.washington.edu/chudler/sign.html

I have seen some Pakistani kids using a very particular way of
counting with their fingers and they move their fingers very, very
fast making really quick calculations (just a comment).

I believe that learning 20,000 combinations is not a big issue as
in "taquigrafia" people normally learn it as adults and they
certainly are required to have a very extensive vocabulary for use
in court, maybe a lot bigger than 20,000.


Then there is the practical factor that gave me a reason to start
this. I gave this toy to some kids in the rehabilitation center and
they WANT IT, they were so exited and the doctors as well.

Anyways, I cant for sure said that this will be a success untill a
lot more testing is done and more people try this out. So I believe
it is worth the try and that gives me a lot of enthusiasm to go ahead
even if it wont be feasible after all.

Hope all this makes sense, I have problems explaining this in
English, but hope it is somehow understandable :). I will send some
pictures sometime soon.


BTW, I also got a lot off feedback of-list, thanks a lot.
