In CRS 3.5, occasionally TTS prompts respond slowly

Core Issue

The issue usually occurs when the Nuance Speech Server, the Cisco Customer Response Applications (CRA) server, the Gateway or the network is operating under a heavy load.

Resolution

To resolve this issue, perform these steps:

  1. Identify and correct any network problems.      
  2. If you are using VoiceXML, you can work around this problem by performing these steps:      
    1. Reduce the complexity of the grammars used in the VoiceXML application.         
    2. Remove the reference to Document Type Definition (DTD) in the VoiceXML application.         
    3. Use local .wav, grammar and VoiceXML files instead of files on another server.
