for more detailed information.

Known Bugs and Limitations
| Bug |
Description |
5144
|
DTMF recognitions produce
incorrect values in the utterance property of the shadow variable and the application.lastresult$ variable.
Currently, utterance is set to a string of the form DTMF-1
DTMF-2 DTMF-pound. The VoiceXML 2.0 specification requires that the
value be set to a simple string of digits and symbols such as "12#".
The specification also requires that the termchar be removed from the
end of the utterance string, which currently is not done.

|
The numeric scale of the
confidence property of shadow variables and application.lastresult$
now
correspond with the VoiceXML confidencelevel
property. The confidencelevel property uses an exponential
scale to map the VoiceXML property values 0.0-1.0 to the Nuance values
1-100. However, the confidence properties of shadow
variables and application.lastresult$ use a linear mapping.
