Go to the Speech Recognition or DPR Configuration screen (Feature Packages > Speech
and DPR Administration > Administration > Speech Proxy Administration > Speech
Recognition Administration > Speech Recognition or DPR Configuration) and administer a
server.
Speech server not running
For earlier releases of OSR, run the command swisvc -start to restart the speech server
after every Avaya IR system re-start.
Starting with OSR 2.x, you can set OSR service to start automatically after every system
restart. To do so, make the following change on the OSR 2.x server:
1. Locate and open the file c:\Program
Files\SpeechWorks\OpenSpeechRecognizer\confg\SpeechWorks.cfg
2. Change the SWIsvcMonAutoRestart and SWIsvcMonAutoStart lines to be set to 1. Verify
that the lines look like this:
― SWIsvcMonAutoRestart=1
― SWIsvcMonAutoStart=1
3. Save the SpeechWorks.cfg file.
Speech response delayed
Delays in speech response may be caused by:
• Inadequate IR system or LAN resources. Managing the performance of your IR system
helps to prevent delays in speech response.
• Limited recognition resources in a speech recognition application. All remote application
resources might be busy and not available for allocation to other calls. You must wait for
resources to become available or increase the number of resources the system can use.
• Overloaded host communications. If interactions between the host and the IR system are
too busy, the result may be delays in speech response.
• Mismatches between the anticipated number of digits in an ANI or DID pass and the
actual number received (R2MFC protocol only). Use the nms command to specify the
anticipated number of digits.
Speech recognition rejecting many responses
ScanSoft OSR 2.0 uses new confidence scores to obtain the recognition result. Some of the
borderline utterances that would have been accepted in OSR 1.x might be rejected in OSR
2.0.
