Greetings. I am running Asterisk 1.4.20.1 with LumenVox & connector (8.0) on a couple Linux distributions (mostly) successfully. However, I have run into an issue where a speech variable is not being set correctly after DTMF use, and I'm not sure if I'm doing something wrong. Consider the following context (the 'answer' and the loading of the grammars are done previously): [lumenvox-test] exten => s,1,SpeechCreate exten => s,n,SpeechActivateGrammar(yesno) exten => s,n,SpeechActivateGrammar(digits) exten => s,n,Wait(2) exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,SpeechDeactivateGrammar(yesno) exten => s,n,SpeechDeactivateGrammar(digits) exten => s,n,SpeechDestroy Here is the behavior when saying "three" during the first beep, and ignoring the second two beeps. As expected, the latter two Noop's don't provide any response: ----- -- Executing [s@lumenvox-test:1] SpeechCreate("SIP/SEND-t0906-08257800", "") in new stack -- Executing [s@lumenvox-test:2] SpeechActivateGrammar("SIP/SEND-t0906-08257800", "yesno") in new stack -- Executing [s@lumenvox-test:3] SpeechActivateGrammar("SIP/SEND-t0906-08257800", "digits") in new stack -- Executing [s@lumenvox-test:4] Wait("SIP/SEND-t0906-08257800", "2") in new stack -- Executing [s@lumenvox-test:5] SpeechBackground("SIP/SEND-t0906-08257800", "beep\|3") in new stack -- Executing [s@lumenvox-test:6] NoOp("SIP/SEND-t0906-08257800", "999") in new stack -- Executing [s@lumenvox-test:7] NoOp("SIP/SEND-t0906-08257800", "3") in new stack -- Executing [s@lumenvox-test:8] SpeechBackground("SIP/SEND-t0906-08257800", "beep\|3") in new stack -- Executing [s@lumenvox-test:9] NoOp("SIP/SEND-t0906-08257800", "") in new stack -- Executing [s@lumenvox-test:10] NoOp("SIP/SEND-t0906-08257800", "") in new stack -- Executing [s@lumenvox-test:11] SpeechBackground("SIP/SEND-t0906-08257800", "beep\|3") in new stack -- Executing [s@lumenvox-test:12] NoOp("SIP/SEND-t0906-08257800", "") in new stack -- Executing [s@lumenvox-test:13] NoOp("SIP/SEND-t0906-08257800", "") in new stack -- Executing [s@lumenvox-test:14] SpeechDeactivateGrammar("SIP/SEND-t0906-08257800", "yesno") in new stack -- Executing [s@lumenvox-test:15] SpeechDeactivateGrammar("SIP/SEND-t0906-08257800", "digits") in new stack -- Executing [s@lumenvox-test:16] SpeechDestroy("SIP/SEND-t0906-08257800", "") in new stack ----- Here is the same call when pressing 3 on the keypard during the first beep, and ignoring the second two beeps: ----- -- Executing [s@lumenvox-test:1] SpeechCreate("SIP/SEND-t0906-a9b004a8", "") in new stack -- Executing [s@lumenvox-test:2] SpeechActivateGrammar("SIP/SEND-t0906-a9b004a8", "yesno") in new stack -- Executing [s@lumenvox-test:3] SpeechActivateGrammar("SIP/SEND-t0906-a9b004a8", "digits") in new stack -- Executing [s@lumenvox-test:4] Wait("SIP/SEND-t0906-a9b004a8", "2") in new stack -- Executing [s@lumenvox-test:5] SpeechBackground("SIP/SEND-t0906-a9b004a8", "beep\|3") in new stack -- Executing [s@lumenvox-test:6] NoOp("SIP/SEND-t0906-a9b004a8", "1000") in new stack -- Executing [s@lumenvox-test:7] NoOp("SIP/SEND-t0906-a9b004a8", "3") in new stack -- Executing [s@lumenvox-test:8] SpeechBackground("SIP/SEND-t0906-a9b004a8", "beep\|3") in new stack -- Executing [s@lumenvox-test:9] NoOp("SIP/SEND-t0906-a9b004a8", "1000") in new stack -- Executing [s@lumenvox-test:10] NoOp("SIP/SEND-t0906-a9b004a8", "3") in new stack -- Executing [s@lumenvox-test:11] SpeechBackground("SIP/SEND-t0906-a9b004a8", "beep\|3") in new stack -- Executing [s@lumenvox-test:12] NoOp("SIP/SEND-t0906-a9b004a8", "1000") in new stack -- Executing [s@lumenvox-test:13] NoOp("SIP/SEND-t0906-a9b004a8", "3") in new stack -- Executing [s@lumenvox-test:14] SpeechDeactivateGrammar("SIP/SEND-t0906-a9b004a8", "yesno") in new stack -- Executing [s@lumenvox-test:15] SpeechDeactivateGrammar("SIP/SEND-t0906-a9b004a8", "digits") in new stack -- Executing [s@lumenvox-test:16] SpeechDestroy("SIP/SEND-t0906-a9b004a8", "") in new stack ----- As you can see, the latter two SpeechBackground's don't return empty values, but instead the original keypad input from the earlier use. This causes a very messy fall-through situation unless you change those variables immediately via a voice and SpeechBackground. Bug or am I doing something wrong? Thanks. Brian J.

Each time you create a 'SpeechBackground' you are resetting the variables as you are grabbing speech again. Try this: [lumenvox-test] exten => s,1,SpeechCreate exten => s,n,SpeechActivateGrammar(yesno) exten => s,n,SpeechActivateGrammar(digits) exten => s,n,Wait(2) exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,Set(SCORE1=${SPEECH_SCORE(0)}) exten => s,n,Set(TEXT1=${SPEECH_TEXT(0)}) exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,Set(SCORE2=${SPEECH_SCORE(0)}) exten => s,n,Set(TEXT2=${SPEECH_TEXT(0)}) exten => s,n,SpeechBackground(beep\|3) exten => s,n,Noop,${SPEECH_SCORE(0)} exten => s,n,Noop,${SPEECH_TEXT(0)} exten => s,n,Set(SCORE3=${SPEECH_SCORE(0)}) exten => s,n,Set(TEXT3=${SPEECH_TEXT(0)}) exten => s,n,SpeechDeactivateGrammar(yesno) exten => s,n,SpeechDeactivateGrammar(digits) exten => s,n,SpeechDestroy exten => s,n,Verbose(1, First time was Result: ${SCORE1} Text: ${TEXT1}) exten => s,n,Verbose(1, Second time was Result: ${SCORE2} Text: ${TEXT2}) exten => s,n,Verbose(1, Third time was Result: ${SCORE3} Text: ${TEXT3}) exten => s,h,Hangup Here you are storing the result score and text for each prompt to a new channel variable, after this you can run another speechbackground to get new scores and text's, just make sure to store them elsewhere before going for another speech interaction. This should point out to you how to store them, and probably give you the missing part where you see why you are rewriting the variables each time you get speech.

Thanks for the reply.

I understand that, and the variables being reset is what I'm expecting.
My point is that it's *not* happening when using DTMF. A
SpeechBackground that does not receive any speech is continuing to use
the result from the *previous* application call when DTMF is used (on the
first of three beeps in my previous example). Let me know if I wasn't
clear with my previous code snippet and sequence of events. Thanks.

Yeah I misunderstood previously. I think that DTMF stores in another variable (${EXTEN}?) when doing that, I will have to dig into some of my speech/dtmf code and see what I was doing to handle it when they started using keypress instead.
