The confidence score range for MRCP is not the same as the range for VXML2


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:


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:

To use the range 0 - 100 set the parameter to false:

The default value for the parameter is false.
