•If you want to use the OSR 1.x confidence score scale, set the attribute

swirec_backward_compatible_confidence_scores to 1.1 in the OSR server user configuration file. Refer to the Scansoft OSR 2.x reference manual for further information.

•If you want to use the OSR 2.x confidence score but you want to increase the recognition rate, try decreasing the confidencelevel property in the /vs/data/vxml/defaults.xml file on the Avaya Interactive Response system, then restart the voice system.

Speech recognition not working

If Avaya speech recognition is not working, the cause may be:

•Incorrect or incomplete administration of the Natural Language Speech Recognition feature or proxy speech server on the IR system

•Disconnection or malfunction of the proxy speech server

•Inadequate LAN or proxy speech server resources (for example, CPU usage at or above 80 percent)

The procedures in this section explain what to do when speech recognition is not working at all. PROXY alarms and messages contain repair procedures for a variety of speech recognition problems.

Speech not playing

Speech may not play for a variety of reasons, including the following:

•The voice response application does not contain, or fails to find, the required phrase.

•The required voice response application is not assigned to the channel.

•A proxy server providing Text-to-Speech service is disconnected or experiencing intermittent problems.

Checking the voice response application and system administration

To check the application and the administration settings:

1.If a particular phrase of recorded speech is not playing, check to see that it is recorded and record it, if necessary.

2.Go to the Display Equipment screen (Configuration Management > Voice Equipment > Display Equipment) and check to see if the correct service is assigned to the channel or channels.

3.If the correct service is not assigned, go to the Channel Services screen (Configuration Management > Voice Equipment > Voice Services > Channel Services) and make the required changes.
