Installing Nuance Speech Recognition (ASR)

Please contact sales@voiceguide.com to arrange Nuance licenses and access to Nuance software.

Please refer to Nuance documentation for Nuance installation instructions.

The Nuance MRCPv2 server by default uses port 5060 to accept incoming speech recognition requests. This is the same port used by most VoIP/SIP applications. When running the LumenVox MRCPv2 server with that default setting, no other VoIP/SIP applications should be running on same server.

 

Nuance Configuration

Please refer to Nuance documentation for configuration instructions.

Before connecting to Nuance using MRCPv2 this Nuance file must be edited:

C:\Program Files (x86)\Nuance\Speech Server\Server\config\NSSserver.cfg

The entry:

server.mrcp2.sip.contact.useHostIPAddress

Must be set to: 1

After the above change the Nuance Speech Server service must be restarted.

 

VoiceGuide Configuration

VoiceGuide connects with Nuance Recognizer using MRCPv2.

The connection parameters are set by adding a client configuration entry in VoiceGuide's \conf\client-profiles\ directory.
Sample files are provided in that directory.
VoiceGuide will read in all .xml files present in that directory
Any sample configuration files need to be first edited to specify the IP address of the ASR server, and then renamed to .xml in order to be read in by VoiceGuide.
