1088.0. "Speech recognition systems" by BBRDGE::LOVELL (� l'eau; c'est l'heure) Tue Feb 15 1994 00:30

	An interesting article appears in this month's PC
	Magazine (UK edition) reviewing the IBM Personal
	Dictation System (retailing at �415).

	After 20-30 minutes of training, you can dictate
	at 90 words per minute with 85-95% recognition of
	commonly used English speech.  Special dictionaries
	are available for specific professions (e.g. medical, 
	insurance, journlism).  Also the article claims that
	the technology is language independent except for 
	largely tonal based languages (e.g. Indo-Asian
	languages).

	The system gets a thumbs up by the reviewer - certainly
	positions IBM as having excellent researchers and
	an organisation that takes ideas and turns them into
	products at affordable prices.  This set me wondering -
	where is Digital with speech recognition?  Surely
	a few spare Alpha/AXP cycles could help with a software
	only implementation of speech recognition?

	Lastly, the IBM system is not perfect.  Below is the
	first verse of a famous poem by Lewis Carroll as 
	"recognised" by the system.  Can anyone reverse-
	reconise it?  

	'Twould be nice to see it in the original "English" if
	someone remembers it exactly.

    Let's try...
    
    "Twas brillig and the slyvie toths did gyre and gimbal in the wabe. 
    All mimsey were the borogroves and in the mome wrath grabe."
    
    Strange, this fouled up in the spell checker :-(
1088.2Maybe the spell checker was right.PASTIS::MONAHANhumanity is a trojan horseTue Feb 15 1994 01:342
    	I'm not surprised! It's "slithy" not "slyvie" and the mome raths
    outgrabe.
1088.3REGENT::BROOMHEADDon't panic -- yet.Tue Feb 15 1994 09:593
    It's "slithy toves", not "toths".

I spent a year using bits of Jabberwocky as "pass-phrases". This 15 character
minimum length monthly change is a pest!

    Hey M Monahan, I caught you!  The spelling checker was right twice, you
    deleted your first version of .2 and corrected the spelling of "slithy"!
    Cheater!

    	OK, I'll admit I changed it, but I didn't use any form of spelling
    checker - just went off to the WC, and while pondering there remembered
    what I had done wrong.

    Hmm, such a boring, straight response in .6.  Of course, it would be
    quite some spell checker that would catch non-words like "slithy" ...
    and it would be quite some speech recognizer that would catch non-words
    like "slithy" ... OK, now we can wonder what the speech recognizer
    would come up with in the WC :-)

    This IBM speech recognizer isn't the first on the market, certainly.  A
    colleague in my group uses a PeeCee application called Dragon Dictate. 
    And in fact IBM does have a technology-sharing agreement with Dragon; I
    wonder how much of this new product is Dragon's technology.
    
    Dragon is rather more epxensive; its original version cost about $1500,
    and the current model is still pricey.  It's a combined hardware/
    software product, using a special audio input card.  The IBM unit's
    price does seem attractive.
    
    Dragon does not have the kind of vocabulary limitation that the IBM
    unit seems to have, judging from the "special dictionaries" info.  It
    is provided with a vocabulary of about 80,000 words and can store in
    the hundreds of thousands.  Initial training is on the order of 20
    minutes.
    
    Speed of Dragon is easily as good as IBM's.  On paper.  (I timed my
    colleague saying a short paragraph.)  In the real world, both systems
    will be slower because you must constantly correct misinterpreted words
    or the system will learn the erroneous versions and consider them to be
    correct.  My colleague says real-world speed is more on the order ot
    15-25 words per minute for Dragon, and I'll bet IBM isn't any better.
    
    Does the IBM model work with Windows?  Dragon doesn't - if you run
    Windows, it goes away.  But it comes back when you exit from Windows.
1088.9JIT081::DIAMOND$ SET MIDNIGHTWed Feb 16 1994 18:164
    Surely the equivalent of a spelling checker would instruct the
    dictator to open the mouth wider or reposition the tongue or
    just plain speak up, etc., instead of placidly accepting
    corrections to misinterpretations :-)

    	If such a thing existed it could be valuable for teaching various
    types of handicapped people.
1088.11DECWET::GETSINGERWe ARE the GovernmentThu Feb 17 1994 09:051
    Didn't Henry Higgins work on this for a while?
1088.12BBRDGE::LOVELL� l'eau; c'est l'heureFri Feb 18 1994 05:2615
	Nope it doesn't work (well) with Windows.  That was one of the
	reviewer's gripes.

	Regarding correction - I believe there are two ways - one is simply
	editing with no feedback, the other calls up the training
	sequence and prompts you through that particular difficult
	word so that it is better prepared in the future either by
	being tuned to the speaker or by having augmented a personal
	dictionary.

	Dragon seems to be a fundamental technology component in this 
	business.  I believe that my Microsoft Sound card which provides 
	a voice menu command system has a Dragon chipset, although it has 
	extremely limited word recognition capability.

.8    >wonder how much of this new product is Dragon's technology.

    As I understand it, IBM is competing with itself... Personal
    Dictation System is IBM's own technology. IBM also resells
    DragonDictate under the name VoiceType. The audio card that
    DragonDictate uses is from IBM. (And to answer the earlier question
    about where Digital is with this technology, we resell DragonDictate
    too.)
    
    Further discussion probably belongs in
