In the crowded IVR Tools market and competing technologies for making IVR development easier and faster, I thought it would be an worthwhile to know how many people use what kind of IVR development tools for their IVR Software.

POLL to find out % of IVR Tools users

So, I though I would start a poll in this IVR Blog to find out how many uses what kind of IVR development tools. Though I tried to add as many as possible tools, I may have forgotten to add some. Please leave comment with the IVR Tool and I would update the options.

The poll is at the right side this blog just below the SEARCH Textbox. I request all kindly to vote. Once may choose 2 or more choices.

I hope to publish the result after a month or so with country wise data too.

Happy voting!

One of the often-mentioned advantages of IVR Toolkit like VBVoice, Velocity etc. are its quick implementation of IVR system. To be more precise, implement the IVR call flow quickly with minimum requirement of coding!

While this is quite true that IVR Toolkit removes the requirement of coding the mundane subroutines interfacing the CTI boards, but question arises, is this advantage exclusively belong to IVR Tool-kits only ? I think otherwise! This advantage is equally shared by hard core C or C++ coding from old-school of IVR development!

IVR Tool-kits in a way can be considered modern day compact point and shoot digital cameras where anyone capable of pressing the shutter button can take beautiful pictures! And the learning curve to take picture consists of just three steps :

1. Insert batteries and switch on the camera
2. Point to the object and see the on the LCD screen
3. Press shutter button and look at the captured picture on LCD screen!

Rest of the things would be like aperture, shutter speed, ISO would be taken care by the camera itself! Similarly, with IVR Toolkit, just install the toolkit in your development tool like Microsoft Visual Studio, drag and drop the ‘IVR Controls’ to ‘define’ call flow your IVR and then compile and run! The IVR would be ready!

Now think of DSLRs or old SLR cameras which is used by professional photographers which offer them controls on Aperture, Shutter Speed, ISO as well as many other parameters to control light for a better picture! This breed of photographers still stick to SLR cameras precisely because of the controls over those aperture, shutter speed, ISO etc. !

Similarly, old school IVR development, IVR coders have control over CTI boards completely without depending on any third party tools! They have direct access to APIs those control all telephony related functions like sensing incoming call, ISDN PRI command exchange and much more!

And as for the quick implementation of call flow, they can implement fast too, simply exploiting another old school technique called ‘re-usable code’. Over the years, C++ programmers have also developed their re-usable code for controlling all basic CTI functions which they can use in any new IVR applications. The call flow of an IVR is nothing but a smart switch structure which does fixed set of tasks like playing audio file, detecting DTMF or speech recognition, connect call or disconnect calls!

And there is a time tested, excellent tool for re-using code which is widely known as “Copy-Paste”, just copy the code of subroutines or functions ( which control the CTI board) and paste them in your new project with new call flow and you are done!

So, the quick implementation of any IVR call flow is also possible by seasoned and experienced C++ IVR developers. But, for a beginner, most probably, IVR Tool kit is the best option to develop their IVR Systems in quickest possible time provided they already know some development tool supported by the IVR Tool kit. FOr example, if some one know C# or Microsoft .NET, one can easily build IVR application using Velocity or VBVoice.

Like many emerging services and technologies, development of IVR services too have many competing methods to develop IVR software. While Googling, interacting with various IVR companies, professionals I have found out some different types of IVR development tools or ‘school of thought’ as they call!

IVR Development Tools

Here are few I have thought of :-

1. Old School Of thought – Using built in API in C++ provided by the CTI manufacturers.

This type of IVR developers are decreasing and might become extinct in future! Most probably, Dialogic, Synway and Donjin may provide some lifeline to this kind of IVR developers as they are few CTI manufacturers with well documented API in C++. Old IVR programmers like me still prefer API and C++ as it gives power!

2. Web Style development – VXML, CCXML, VoicePHP

This kind of IVR developers treat IVR software as website or portal ( now we know why they call voice portal) and want to use simple tags for interacting with caller. This is intended to be open standard which will use a VXML Browser ( just like web browsers). VXMl browsers are available on Asterisk as open source also commercially available from Voxeo, I6net, Phonologies from India. Few CTI manufacturer like Digium, Sangoma etc. support this kind of IVR development tools.

3. Extension of Traditional Development tools like Microsoft .NET – VBVoice, Velocity

This kind of IVR tools reside in traditional powerful development environment Microsoft .NET technologies. They are very powerful and does not need any learning curve as conventional C# or VB is used for coding while using the Telephonic or CTI interfaces as component just like any button in the form. This kind of IVR development is gaining momentum now for the obvious reasons.

4. Complete New Tool with simple drag and Drop visual tools – Envox, Invox, Osidail, XtendIVR, OmniVox3D

This kind of tools comes as a complete solution which has its own GUI tool to drag and drop for making IVR call flow, test them offline, compile them and even port to VXML code to host in another hosting platform! With recent advancement in internet, this kind of tools are completely online and developers can just create an account and then start developing their IVR software! I think, the number of this kind of tools are highest at present.

So, these are four majorly available IVR development tools and every tool has merits and demerits. Most probably, a choice of IVR development tool would mostly depend on type of IVR software.

The one similarity in all above available tools are, they are licensed per channel basis. Developers has to pay per channel for their production IVR software for using the development tool or VXML browser.

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.
