How Dragon works
ThegoalofDragonNaturallySpeakingistomakeiteasiertointeractwithacomputerwithout
usingakeyboardormouse.Tosucceedatthisgoal,theprogrammustbeabletoanalyzean
incomingstreamofsoundsandinterpretthosesoundsascommandsanddictation.This
processofinterpretationiscalledspeechrecognition,anditssuccessismeasuredbythe
percentageofcorrectinterpretations,orrecognition accuracy.
Toachievehighrecognitionaccuracy,DragonNaturallySpeakingreliesonseveralsourcesof
information:
n Acoustic model—amathematicalmodelofthesoundpatternsusedbythespeaker's
language.
n Vocabulary—alistofwordsthattheprogramcanrecognize.Eachwordinthe
Vocabularyhasatextrepresentationandapronunciation.
n Language modelstatisticalinformationassociatedwithaVocabularythatdescribes
thelikelihoodofwordsandsequencesofwordsoccurringintheuser'sspeech.
WhenyoucreateandtrainaUserProfile,youstartwithastandardsetofmodelsandthen
customizethemforthewayyouspeak(acousticmodel)andthewayyouusewords
(Vocabularyandassociatedlanguagemodel).WhenyouuseDragonNaturallySpeaking,the
programusesyourcustomizedUserProfiletoguessthewordsthatyousaid.
Why does the program make mistakes?
Forvariousreasons,DragonNaturallySpeakingdoesnotalwaystypethewordyouwant.
Someofthereasonsinclude:
n ThecorrectwordwasnotintheVocabulary.
n Thewordorphraseyouspokesoundedverysimilartothewordorphrasetheprogram
