server.mrcp2.osrspeechrecog.mrcpdefaults.
VSP.server.osrspeechrecog.result.mediatype
VSP.server.osrspeechrecog.result.mediatype
Specifies the media type of the recognition result returned to the application.
Value |
MIME media type supported. DEFAULT: application/x-vnd.speechworks.emma+xml;strictconfidencelevel=1;mrcpv=2.06 Note: strictconfidencelevel is not supported for Dragon Voice recognition. |
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 used. |
The default value returns NLSML (Natural Language Semantic Markup Language) results. In addition to the default, this parameter accepts the following values:
Accepted value | Description |
---|---|
application/x-vnd.nuance.emma+xml |
Uses the EMMA format. |
application/x-vnd.speechworks.emma+xml |
Uses the NLSML format. |
application/x-vnd.speechworks.recresult+xml |
Uses the SpeechWorks format. |
application/x-vnd.speechworks.wordlattice+xml |
Uses the wordlattice format for getting raw recognition results. |
Note: When you use the flag mrcpv=2.06 the returned confidence scores are floating point numbers between 0 and 1 (up to 2 decimal values). Without the flag, the scores are between 0 and 100.
The strictconfidencelevel flag always has the value "1". When you specify it, Recognizer returns only results with a confidence level that is higher than Confidence-Threshold. When you remove the flag (by removing the string "strictconfidencelevel=1"), Recognizer returns all recognition results.
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
