server.mrcp1.osrspeechrecog.result.mediatype
Specifies the media type of the recognition result returned to the application.
Value |
Media type DEFAULT: application/x-vnd.speechworks.emma+xml;strictconfidencelevel=1 |
How to set |
If using the Management Station, set on the Speech Server service. If not using Management Station, set in an NSS configuration file (user-NSSxx.txt). |
Usage |
Rarely changed from default. Applicable for Nuance Recognizer. Not applicable for Dragon Voice recognition. |
The default value returns NLSML (Natural Language Semantic Markup Language) results. For EMMA (Extensible MultiModal Annotation markup language) results, use:
application/x-vnd.nuance.emma+xml;epmetrics=1;strictconfidencelevel=1
When strictconfidencelevel is present, Nuance Recognizer returns only results that have a confidence level that is higher than Confidence-Threshold. When strictconfidencelevel is not present, Recognizer returns all recognition results. To disable it, remove the string "strictconfidencelevel=1" from the parameter value.
Note: If it is present, the parameter must always have the value "1".
For example, let’s say our nbest list + confidence is:
- .5
- .4
- .3
If strictconfidencelevel is set and minconf is .45, then our nbest list will be:
- .5
Whereas if strictconfidencelevel is not set, the nbest list will be:
- .5
- .4
- .3
