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:

  1. .5
  2. .4
  3. .3

If strictconfidencelevel is set and minconf is .45, then our nbest list will be:

  1. .5

Whereas if strictconfidencelevel is not set, the nbest list will be:

  1. .5
  2. .4
  3. .3

Supported for MRCPv1 browsers. (Ignored for MRCPv2 browsers.)
