Abstract

Disclosed is a user interface in which a touch screen input is used, in a system with speech recognition, to switch between an Information Entry mode, in which, for example, dictation can occur with the system being used as a word processor, and a Command and Control mode, in which pre-determined code words are uttered to elicit certain system functions.

User Interface with Speech Recognition and Touch Screen Inputs

      Disclosed is a user interface in which a touch screen input is
used, in a system with speech recognition, to switch between an
Information Entry mode, in which, for example, dictation can occur
with the system being used as a word processor, and a Command and
Control mode, in which pre-determined code words are uttered to
elicit certain system functions.

      Speech recognition systems conventionally use code words for
this purpose.  When the system is operating in the Information Entry
mode, the user utters a particular code word to switch into the
Command and Control mode.  Another code word switches back to the
Information Entry mode.  However, unwanted switching from the
Information Entry mode occurs when the particular code word is
uttered by someone in range of the microphone of the system, or when
the particular code word is included in information being dictated.

      With the presently disclosed interface, the user touches any
point on the active surface of touch enabled display to switch from
the Information Entry Mode to the Command and Control mode.  The
interface is previously programmed by the user to operate either as a
toggle, with the screen being touched briefly to switch in either
direction between modes, or as a pushbutton, with the screen being
touched continuously to hold the system in the Command and Control
mode.

      A command word such as "mute" is used t...
