Created by: Heidi Tran on 14-09-2011 10:47:52 AM Using IOS 12.4(24)T3, CVP 7.0(1), Nuance Recognizer 9 Have several audio elements and a form element. The audio elements are mixed audio, one TTS and some say-it-smart recorded prompts. After playing the TTS message, we are unable to barge in. To isolate the barge in issue, we noticed that if we remove the TTS message, barge in works fine. The gateway logs and wireshark logs on NSS server do not show the barge in dtmf keys at all. It is like the keys were simply ignored. Has anyone ever encountered this before?

Tell me what happens. Not suggesting that this is a solution, Trying to check something here.

Thanks Hemal for the response. However, adding the silence audio with bargein disabled didn't make a difference. I was still unable to bargein after the TTS message played.
For the silence audio do one thing. Do not use audio element, use menu 2 option element with bargein enabled and silence audio. Also set noinput timeout to 1s. Try this and let me know. Is the TTS you are getting dynamic or static. If it does not work: Also just for the sake of it can you put another static tts message before this audio with bargein enabled and let me know what happens. Do you have logs from the ASR ?
Subject: RE: Barge in issue after playing a text to speech message Replied by: Heidi Tran on 22-09-2011 10:54:05 AM Hemal, Adding the menu 2 option seemed to do the trick. I am now able to bargein now after the TTS message plays. However, there is STILL one section where I can't barge in. See Audio element 3, the first say-it-smart currency. I also tried adding a small silence before it, but it still didn't help. Everywhere else it is now working fine after adding your menu suggestion. This is alot better than before when I couldn't barge in at ALL after the TTS message.
Here is the call-flow: Audio element 1: recorded audio say-it-smart date recorded audio
Audio element 2: TTS message
Menu 2 option element (added per your suggestion) recorded audio
Audio element 3: say-it-smart currency recorded audio say-it-smart currency
Form element recorded audio voice and dtmf grammar
Yes I do have logs from ASR and have also collected wireshark logs on the NSS server. We are unable to see the barge in attempts. It is never sent. I have sent to TAC and they are still investigating.
Thanks,

Audio element 3 or 2 option Menu as before say-it-smart currency
Audio Element 4 recorded audio say-it-smart currency
Let me know what happens. You may not want to necessarily implement it this way if it works. However the buffer may not be getting cleared. Just want to check.
Hemal
