Data collection feature

Type of feature

Data Collection is a base feature.

Using this feature

The Data Collection feature provides support for collecting speech samples for application debugging and for building model applications for Natural Language Speech Recognition (NLSR).

To begin data collection, edit the file /vs/sproxy/cfg/OPSR#.cfg to include the entry DataCollection=yes, then stop and start the voice system. Once the voice system starts, data collection will happen for all calls.

Caution:
The data collection files can be very large and the processing involved with data collection can adversely affect performance of the target system. Use data collection only for application debugging, then stop data collection.

To stop data collection, edit the file /vs/sproxy/cfg/OPSR#.cfg in one of the following ways, then stop and start the voice system:

• Change the entry to DataCollection=no
• Delete the DataCollection=yes entry
• Add a # sign at the beginning of the DataCollection=yes line

Use data collection by implementing the following proxy external functions in TAS applications:

• Get data collection files for analysis (getdcPROXY)
• Remove data collection files when they are no longer needed (rmdcPROXY)

For VoiceXML applications, data collection will be turned on for all calls when DataCollection is set to yes. There is no control over data collection for individual calls when using VoiceXML.

For more information about using external functions in TAS applications, see Using TAS script instructions and the IVR Designer for TAS Online Help.
