[Freeswitch-users] Speech Input Timeout issue

[Glen Ganderton]

Just to add to this again, I also get this random error "RECOGNIZER channel error!" and the only way for ASR to start operating again is to restart freeswitch.

Just to add one more thing, when I was simply using the XML dialplan I didn't seem to have this issue. It may be an issue with my lua ivr script. Im just learning to program in lua and have hacked something together. So if you want to have a look maybe you will see an issue with it.

Hi Guys,

I am in the process of configuring an speech recognition IVR using freeswitch and nuance, with the module unimrcp to link them.  This seems to be working fine, I have create a basic IVR script that works well however  around 50% - 60% of calls fail with some sort of input timeout issue.

Here is a few relevant lines of the log file for a successful call:

Here are a few lines for an unsuccessful call:

It seems to me the main difference is that in the successful call there is a timer that is set. Has anybody seen this issue or have any idea's on how to resolve it?
