Prompt (with barge-in enabled) times out before playing completely

Last Updated : Jan 13, 2020 |

If the default value of session timeout (60 sec) is shorter than the prompt, and barge-in is enabled in the application, the recognition event reaches timeout before the prompt is played completely.

Proposed Solution

About this task

Note:

This modification is required only if the customized application has a long play prompt with barge-in enabled, that exceeds the recognition session timeout.

To prevent timeout before the long prompt play is complete:

Procedure

  1. Log in to the NSS speech server.
  2. Navigate to the $NSSSVRSDK directory.

    The environment variable$NSSSVRSDK points to

    /usr/local/Nuance/SpeechServer_5/server/config (for NSS )

    Or

    /usr/local/Nuance/Speech_Server/server/config (for NSS). For more information on speech server versions, see Avaya Experience Portal Overview and Specification.

  3. In an ASCII editor, open the NSSserver.cfg file.
  4. Modify the following parameters:

    server.mrcp2.sip.sessionTimeout VXIInteger 120000

    server.mrcp1.rtsp.sessionTimeout VXIInteger 120000

    Note:

    The timeout value should be greater than the prompt play length.

  5. Save and close the file.
  6. Restart the NSS speech server.
