The confidence score range for MRCP is not the same as the range for VXML2
Problem
MRCP returns a confidence score in the range 0 - 100 whereas VXML2 expects a score in the range 0 - 1.
Resolving the problem
A new parameter has been added for use in /var/dirTalk/DTBE/dtj.ini:
wvr.use.vxml2.confidencerange
This controls whether, in a system using MRCP, the confidence scores are returned to the VXML2 application in the range 0 - 100 or 0 - 1.
To use the range 0 - 1 set the parameter to true:
wvr.use.vxml2.confidencerange=true
To use the range 0 - 100 set the parameter to false:
wvr.use.vxml2.confidencerange=false
The default value for the parameter is false.
