Speech recognition such as command and control speech recognition generally use a context free grammar to constrain the decoding process. Word or subword background model are constructed to repopulate dynamic hypothesis space, especially when word spareness is at issue. The background models can be later used in speech recognition. During speech recognition, background and conventional context free grammar decoding are used to measure confidence. The discussion above is merely provided for general background information and is not intended to be used as an aid in determining the scope of the claimed subject matter.

A field emission device (10) includes a base (12), a conductive paste (16), and at least one carbon nanotube yarn (14). The at least one carbon nanotube yarn is attached to the base using the conductive paste. This avoids separation of the at least one carbon nanotube yarn from the base by electric field force in a strong electric field. A method for making the field emission device includes the steps of: (a) providing a base; (b) attaching at least one carbon nanotube yarn to the base using conductive paste; and (c) sintering the conductive paste to obtain the field emission device with the carbon nanotube yarn firmly attached to the base.
