Avaya Aura Experience Portal (AAEP) 6

Reference Number: AA-01695 Views: 4480 0 Rating/ Voters
Introduction

This document describes configuration notes for the LumenVox ASR and TTS servers running with the Avaya Aura Experience Portal (AEP) version 6.0. 

LumenVox does not support the ability to test our ASR and TTS directly from the Orchestration Designer's Application Simulator.We recommend deploying applications made from OD into AEP to test them.

This document was written for LumenVox 10.4.320, though it should apply for any post-10.0 release of LumenVox.

LumenVox Configuration

There are only two changes from the default configuration that must be made, both to the /etc/lumenvox/media_server.conf file:

  1. The value of mrcp_server_ip must be set to the IP address of the machine that LumenVox is installed on. This must be an IP address that the AEP machine can reach and route traffic to. Please contact LumenVox Support for questions about configuring firewalls if they will be running.
  2. The value of compatibility_mode must be changed from the default 0 to 1

AEP Configuration - ASR

When adding a LumenVox ASR to the AEP Speech Servers, the following settings should be used. The two highlighted settings indicate deviations from AEP's default values and so special care must be taken to set these correctly:

  • Enabled: Yes
  • Engine Type: Nuance
  • Network Address: <ip of the machine running LumenVox>
  • Base Port: 554
  • Total Number of Licensed ASR Resources: <number of licenses installed>
  • New Connection per Session: Yes
  • Languages: en-US
  • Ping Interval: 15
  • Response Timeout: 4
  • Protocol: MRCP V1
  • RTSP URL: <ip>/media/speechrecognizer

An example screenshot from the AEP configuration follows below as Fig. 1:

AEP Configuration – TTS

When adding a LumenVox TTS to the AEP Speech Servers, the following settings should be used. The highlighted settings indicate deviations from AEP's default values and so special care must be taken to set these correctly:

  • Enabled: Yes
  • Engine Type: Nuance
  • Network Address: <ip of the machine running LumenVox>
  • Base Port: 554
  • Total Number of Licensed ASR Resources: <number of licenses installed>
  • New Connection per Session: Yes
  • Languages: en-US
  • Ping Interval: 15
  • Response Timeout: 4
  • Protocol: MRCP V1
  • RTSP URL: <ip>/media/synthesizer (note that the end of this URL should be synthesizer and not speechsynthesizer)

An example screenshot from the AEP configuration follows below as Fig. 2:

AEP Configuration – Application

When configuring an application to make use of the LumenVox ASR+TTS in the AEP configuration manager, there are a few notes to be aware of:

  1. Because the Engine Type parameter was set to Nuance, the ASR and TTS will show up as "Nuance" in the Speech Servrs dropdown list within an application's configuration screen.
  2. Under Speech Parameters, be sure and set Speech Complete Timeout to a non-zero value (0 is the default). 800 ms is our recommended value. The other settings can be left blank.
