3. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 3 Speech Confidence Threshold  Configured on each VUI directory handler  Values range from 0 to 100 (default is 10)  Lower values will return more name matches  Higher values will return less name matches  Tune lower if the list consistently does not include the user’s target  Tune higher if the list consistently includes many extraneous names

4. © 2006 Cisco Systems, Inc. All rights reserved.Cisco ConfidentialPresentation_ID 4 Name Matches  User speaks a name  System may return 1 or more name matches  If the highest scoring match is a name, then no extension matches will be returned  The list is sorted by confidence score
