VoIP softphone with Speech to Text function in C#.NET

Hello Everybody, I would like to share one of my new experiences related to .NET and VoIP. Recently I have read about a software which was written in .Net 4.0. You can find the source code of it too. It is a VoIP softphone and it can forward and receive calls and it has speech to text function. It means that it can record the telephone conversation on the basis of keyword. And in addition it is possible to convert this voice record to text format. And later you can search in the text on the basis of the given keywords. I think it is very useful in many cases in the lives of companies. If you are interested in, You can read about this solution here: http://voip-sip-sdk.com/p_135-c-speech-to-text-voip.html
