Recently noticed that there have been repeated questions from our developer community complaining that they can't seem to get the beep to work with <record>. They have set the beep attribute to "true" alright, and the reference guide even says this is supported but why doesn't it work?

Earlier today, as I was typing a comment in our internal issuing-tracking system, I hit backspace to correct a typo. WHAM! I go back to the previous page, and my long-winded comment is gone. Apparently I somehow left the context of the text area (did I tab, or spuriously click, or??), which causes backspace to act as a hotkey for "Back". The web browser was not very forgiving of my mistake.

Are your IVR applications forgiving? They should be.

If you're using JNDI to connect to your database through Tomcat, then it's possible you've had to deal with database connection pool leaks. Your code tests fine, it's been reviewed, but in load tests or in production your app is unable to acquire database connections, the pool is empty!

Fear not, there are some handy parameters which can be set in your application's XML configuration file (in tomcat/conf/Catalina/YOUR_IP/YOUR_APP.xml):

who detects bargein, dtmf, sensitivity?
Answer
6/3/08 11:13 PM
when working with MRCP protocol and the voice gateway and nuance ASR, is it the voice gateway or the ASR system that detects bargein?

I'm asking because I'm having trouble with bargein. And I'm wondering whether the VG should be detecting the voice input and aborting the prompt, or whether it's the ASR that should detect the voice input and tell the VG to abort the prompt.

Similar question, Is it the vg or nuance that should be incorporating the 'sensitivity' parameter? I ask because when I change the value of 'sensitivity' in the application, I see it in the MRCP log on the MRCP server, BUT the system doesn' t seem to be any more or less sensitive to signal vs. noise.

Thanks, Janine

Hi Janine,

Bargein:
During prompt playback, upon user utterance(i.e bargein event) the VG streams the same to the ASR, which would recognize the event and then inform the VG to stop the prompt playback and hence bargein. So basically the bargein functionality depends majorly on ASR and partly on VG.

Sensitivity:
I believe its a speech rec property that is set in the application that gets reflected in the ASR, in the sense its a parameter used to tune the ASR on how good or better the recognition should be based on the noise/signal levels. Its actual effect to being sensitive to noise is part of the ASR.

Cheers,
Ranjana.
