Hey Arsen,

Our Cisco CVP Application is integrated with uniMRCP Servers and Lex V1 Plugin is setup on those MRCP Servers. We have Perpetual Primary and Backup Licenses for MRCP servers hosted on RHEL7 and both are configured in Cisco PCCE 12.0 VVB Servers, reachable on Port 5060.

The issue is, After i input something in the form of Speech and DTMF, i am getting significant amount of Delay like 20-40 seconds and then i get back the response to CVP Application.

Should i change any settings to get this working. Kindly help me on this issue.

We discussed this issue with Chandra offline. I am posting a response here for others possibly encountering the same or a similar problem.

There is a key difference between the Lex V1 and V2 APIs, which may not seem obvious. And the difference is in streaming speech transcription, intent detection supported by Lex V2 but not V1. Having the ability to stream data in realtime helps with speech endpointing. And this is where the Lex V1 plugin may struggle not being able to reliably determine end of speech in a noisy environment. Everyone is encouraged to migrate to Lex V2 which allows to have better user experience.
