Speech Completion
From: NASA Tech Briefs Insider - 01/20/2009

Speech completion is a speech interface function that helps a user enter a
word or phrase by completing a phrase fragment uttered by the user. Using a
filled pause, the technology enables a user to effortlessly invoke the
speech completion function, which helps the user recall uncertain phrases
and saves labor when the input phrase is long. When a user hesitates by
lengthening a vowel during a phrase, the system immediately displays
completion candidates whose beginnings acoustically resemble the uttered
fragment, so that the user can select the correct one.
