[asterisk-speech-rec] How to enable N-Best decoding?

[Scott Stingel]

Hello-

I'm running the Lumenvox 7.5 engine, the Lumenvox 1.4 connector, and 
Asterisk 1.4.3.   All is well, except that the N-Best feature does not 
seem to work.  As I understand it, this feature allows the recogniser to 
return multiple possibilities for the decoded recognition.

What do I have to do to enable this?   An excerpt from the 
DecodeServerLog.txt file shows these interesting lines before each 
decode.  Perhaps the "NO_OOV" is important?
