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.
