List of RAD Tools for Developing IVR Software

I have been thinking to prepare a list of RAD(Rapid Application Development) tools for developing IVR software or voice applications for long time. I have found 8 RAD tools ( including one free tool) for developing IVR Application so far and I think there may be more as I am quite sure, many IVR RAD Tool companies do not use SEO techniques to rank high in search engines! Or may be, Google does not know everything on net, after all.

I have tested only one among this list of 8 tools, VBVoice 5.6.1 of PRONEXUS, and I must admit, I am impressed with how they have made developing IVR software easy and quick! And I am sure pride of many people will be dented as who were member of exclusive and minority group of IVR developer using native API of CTI boards, including myself. I hope to download evaluation version of all the tools one day and compare all of them.

I would say, not all in this list of eight RAD Tools for developing IVR software may qualify to be called complete rapid application development tools, and here is the list:-

1. VBVoice 5.6.1 from PRONEXUS INC:-
I think this is the biggest RAD tool for IVR Software development. Very powerful, easy to use tool that uses industry standard programming environment like .NET technology. It has support for large speech and telephony technologies like ACD, SIP, HMP, MRCP, ASR, TTS and VoIP. If anyone knows VB.NET, C# then with this VBVoice 5.6.1, he can become an IVR Application developer overnight. They support high end CTI boards of Dialogic as well as other CTI boards from vendors like Donjin.

2. VoiceGuide by Katalina Technologies
Another powerful RAD tool for developing IVR. It has its own script and visual editor to write IVR Call flow. It has support for Microsoft SAPI. I feel this is a good tool to start with IVR application. They claim to have more than 5000 clients in their website.

3. Envox 7 from Envox Group
This is another big RAD tools for not only IVR Application, but for many more! It supports IP Telephony, Video Messaging and SMS! One of the key feature of this tool is support for VoiceXML, CCXML and Web Services. It has its own graphical programming environment Envox Studio. It gives good flexibility for developers to develop wide range of voice and IVR applications, most probably ideal for call center solutions. Supports wide range of CTI hardware.

4. Velocity 2.0 by Glorsoft Limited
New kid on the block! “Velocity™ is a completely new technology created by .NET developers for .NET developers.”, It is a new tool, but looks very promising. They support wide range of Dialogic CTI Boards. They have already got prestigious client like London Underground.

5. Xtend IVR 3.0 by Xtend Technologies (P) Ltd
Indian competitor in the field of IVR RAD development tool. This toolkit can be used in various programming languages like VB,VC++, C# etc. They also support speech technologies as well as CTI boards from multiple vendors. They also have a large clientele in India. Free tool for one channel IVR can be downloaded from their website.

6. CT Developer Studio 2 by Pingram Software
CT Developer Studio 2 is a Windows software that helps you quickly implement a professional voice response system into your business. Developing IVR solutions is easy with Visual IVR Script Designer and the many ready-to-use samples supplied with the product. They have their own script, visual script programming environment and simulator. They support Ai-LOgix, NMS and Dialogic boards.

7. Eurovoice objects version 2.0 by Eurovoice Ltd.
They provide COM interface to VB6, VB.net and C# programs for voice or IVR functionality. They mainly support PIKA CTI boards. But they also support PCI express boards from Dalogic. They have speech recognition through MRCP.

8. AGE (Application Generation Environment) version 2.1. by CompTek Internations
AGE is the fastest and easiest way to build voice applications. Best part is, it is completely free, but they charge you for runtime components. It supports Dialogic Voice boards. I think it may not be suitable for large IVR Applications.

I think I would give my top two ranks to VBVoice, Envox 7. Velocity 2.0 is the product to watch out for.

    That’s a nice round-up of the available tools.

    However, just a quick comment to point out that Xtend IVR uses a simple scripting language to implement ivr related tasks including database queries. The interface to multiple programming languages like vb,c#,c++ etc.. is available in case you want to implement more complex functionality.

    There is a video overview of how to use the xtend ivr developer edition and its scripting language at http://www.youtube.com/watch?v=0q6MqtuJkTI

    The usp of the Xtend IVR toolkit is that it supports Pika, Synway, Ai-logix, NMS, Donjin, Dialogic, TAPI and Skype, so no matter which voice card you choose, your script will seamlessly scale to multiple ports and function without any re-coding effort.

    A full-fledged and un-restricted 1 port developer edition is available for download from our site http://www.xtendtech.com/ivr .

    Hi, you didn’t mention one very important tool – Envox CT-ADE what until couple of years ago was called VOS.

  • Uttam Pegu June 28, 2009, 12:39 pm

    Thank you for pointing out about Envox CT-ADE. Though while checking out Envox 7 in envox website, I came across Envox CT ADE too, but I thought I would list their biggest RAD tool Envox 7 only as I was going to list one product from one company. But I agree that Envox CT-ADE is an important widely used IVR RAD tool.

    Hi JayaKrishna,
    I found your comment in spam comments ( Thanx to Akismet Plugin) and discovered today! Akismet anti-spam does not work properly, I guess!

    Thank you for pointing out. I would also add to it that Xtend Technologies (P) Ltd has manpower which are highly skilled, vast technical knowledge on CTI Boards as well as various telecom technologies like SS7, PCM, ISDN etc.

    Pronexus – Sucks crap – Both the company and the people that run the show to the software VBVoice they offer

    I think I would also add the Ozeki VoIP SIP SDK to this list. It also allows to create DTMF IVR system easily with less effort. I used it for my project. YOu may check it: voip-sip-sdk.com/attachments/10/WINFORMS_DTMF_IVR_01.xml


  • Abdul November 16, 2014, 6:24 pm


    I think pronexus VBVoice is the best tool available in market for IVR RAD. Major systems which handles ten thousands of calls of Enterprises like Dubai Airport , Dubai Financial market etc with Speech enabled IVR running on Pronexus VBVoice. One of the most stable system available i guess.
