How to set |
Shown in precedence order (see Rules of parameter precedence): Set in the browser, using the Vendor-Specific-Parameters header in a RECOGNIZE or SET-PARAMS method. In a parameter grammar. In a grammar using a <meta> tag (see the text on recognition-time parameters in Parameters set in grammar files). In Management Station set on the Nuance recognition service. If not using Management Station, set in a Recognizer configuration file (User-nrsxx.xml). |
|
Usage |
Useful when an application saves waveforms for some purpose, or does a playback of collected audio to the caller. Does not affect waveforms saved to the Recognizer’s call logs. |
|
Performance |
Significantly increases the size of the returned result and may affect performance on systems where Nuance speech products and Nuance Speech Server are on separate hosts. |
Browsers usually set this parameter in a RECOGNIZE request, and the parameter automatically reverts to the previous value after the recognition event. (The SET-PARAMS method defines the value for the duration of the session, or until another SET-PARAMS call.)
This property generates the following MRCP header:
Vendor-Specific-Parameters: swirec_return_waveform=”1”
Sample definition in a grammar file:
<meta name="swirec_return_waveform" content="1"/>
