Figure E-0-1 - Voice Quality Task Status Window for a POLQA Test

When generating the output report, Nomad always scores the data using the Scoring Model

specified in the test definition. For example, a test defined with the POLQA scoring model will be

scored using POLQA. Three options exist to score the same data using the other scoring model:

 Re-score Files – On the Data → Complete tab, right-click on the file of interest and select

Re-score Files. The scoring method not used on the previous pass will be used.

 Batch Scoring – This option scores multiple .WAV files using PESQ, POLQA or both. The

output of this utility is a delimited text file that may be viewed in raw form, opened in Excel

or parsed with a script. This utility can be used to score previously unprocessed files or for

re-scoring. Access the Batch Scoring utility from the Data → Utilities tab.

 Offline Scoring – Retrieve and score uplink .WAV files from the Audio Server using either

PESQ or POLQA with this utility. Access the Offline Scoring utility from the Data →

Utilities tab.
