We recently purchased the lumenvox speech lite. The setup and the test went smoothly except the integration with asterisk.

We are using the latest release of asterisk 1.4.2 and the latest release of the lumenvox license server and speech server.

 

The dialplan we are using is as follows, a snippet of the pizza demo, just to test the yes/no output

[pizza]

exten => 200,1,SpeechCreate

exten => 200,2,SpeechActivateGrammar(yes_no)

exten => 200,3,SpeechStart

exten => 200,4,Wait(3)

exten => 200,5,Answer

exten => 200,6,Playback(GP-Greeting)

exten => 200,7,Set(THRESHOLD=0)

exten => 200,n,SpeechBackground(ConfirmPickup,5)

exten => 200,n,NoOp(${SPEECH(status)})

exten => 200,n,NoOp(${SPEECH(spoke)})

exten => 200,n,NoOp(${SPEECH(results)})

exten => 200,n,NoOp(${SPEECH_SCORE(0)})

exten => 200,n,SpeechDeactivateGrammar(yes_no)

exten => 200,n,NoOp

exten => 200,n,SpeechDestroy

exten => 200,n,DumpChan

exten => 200,n,Playback(GP-ThankYou)

exten => 200,n,DumpChan

exten => 200,n,DumpChan

exten => 200,n,Hangup

 

 

 

None of the SPEECH function return a valid response –

 

Your help is much appreciated.

 

Thanks

Sam,

 

Unfortunately there is an issue with the latest connector bridge (b11) and the released versions of Asterisk 1.4.

 

B11 made some changes to to the generic speech API in Asterisk that required the alteration of the way the connector bridge works. Since the 1.4 releases up to this point (so 1.4.0, 1.4.1, and 1.4.2) don't include this updated speech API, the new connector bridge will not work with them. This issue should does affect any 1.2 release.

 

Anyone who is experiencing this issue has a few options. The easiest is to get the latest 1.4 branch from subversion (yesterday I instructed people to grab the trunk -- this was an error, you want the latest code from the 1.4 branch) and build Asterisk from that. As Adrian noted a moment ago, the command to do this is:

 

    svn checkout http://svn.digium.com/svn/asterisk/branches/1.4 asterisk-1.4

 

If you want to continue using 1.4.2, you could just update the speech API by building the latest 1.4 branch and copying the new res_speech.so and app_speech_utils.so into your 1.4.2 system.

 

You could also move back to the b10 bridge. If anyone needs a link to download that, please e-mail me or anyone at LumenVox support and we will be happy to supply it. B11 fixes a few bugs, mainly involving handling DTMF and speech input at the same prompt, so it is generally recommended. It also adds N-best support, allowing you to get multiple results from the Engine, ranked by their confidence scores.

 

The issue will not exist for Asterisk 1.4.3, which should be released very soon.

 

I apologize for this mix-up. If anyone has any further questions about the issue, please feel free to contact me directly or respond on the list.

 

Thanks,
