Handle No Input in IVR App

Posted on January 12, 2012

I am using IVR studio to create an application and everything works great. However, when the program prompt for an answer and the user does not answer or take too long (meaning no input), the system hangs up. Is there a way to add a goto element when there is no input to prevent system from hanging up. Is there a system variable for no input?

Yes, there is a standard way to handle no input, not through a system variable but an exception. All you need to do is select the “noinput” for the transition as shown below:

Using 16K TTS Engine and Voice

Posted on November 28, 2011

we currently have Release 8.1.2. We have created a C# program using the gateway. i wanted to use a better voice than the MS win7 one. The instructions said we had to use 8khz voices. I accidently downloaded a 16khz one. After installing it i noticed it was 16khz, but saw that it did list in the gateway. So I tried a quick test (pressing the test voice button) and it seemed to work fine. Does Release 8.1.2 now work with 16khz voice files?

It looks like the TTS you installed supports both 8K and 16K voices even though its native format is 16K. Some engines, including the MS one, support different output format. If it works, then go ahead and use it.

Use speech recognition in IVR application

Posted on November 14, 2011

How exactly is the speech recognition implemented in speech command? Does one have to call the sapisvr.exe under ‘run command’ ? I cannot find a way to do this this with parameters. Or how to feed whatever is spoken to the recognition engine

Voicent IVR studio and Voicent gateway has built-in support for speech recognition. You do not need to call any other programs in order to use it. The speech recognition engine is the default one and it is part of Microsoft Windows.

To use speech recognition in an IVR application, all you need to do is create a speech command element in Voicent IVR Studio. The following figure shows how it is done:

The RSVP element sets up the system to recognize speech commands, if it recognize “Yes, I will”, it will transition control to the Yes element, which may simple play a thank you audio.
