12. A speech recognition method comprising:
-
starting a synthesis of recorded speech to prompt a user to communicate a user choice, wherein an element in a recognition set corresponds to the user choice; receiving a user speech input signal providing information regarding the user choice; detecting an initial portion of the user speech input signal; selectively altering the synthesis of recorded speech in response to detecting the initial portion of the user speech input signal; and recognizing the user choice, wherein the recognizing includes determining the element in the recognition set which corresponds to the user choice. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
