Speech recognition systems are either speaker dependent or speaker
independent or a combination of both. In a speaker dependent
system the speaker must provide a speech pattern for every word in the
vocabulary by training the software, which, considering the size of an
English speaker�s vocabulary, would be a long and lengthy process. In speaker
independent systems, the software comes with a preexisting vocabulary with
speech patterns already provided; yet, differences in speaker dialects
and ranges of vocabulary (often determined by the application of the software�doctors
and lawyers use a quite different vocabulary subset of the English language
than an average user conversing by email) normally require modifications
of the vocabulary. Generally, the speech recognition systems today
use a common of both, allowing the user to modify a preexisting vocabulary
as needed to match the characteristics of the users voice and to add vocabulary
for the users particular needs.
