Topic: redirecting Skype output speech to TCP socket and receiving in other a



I'd like to create such a system: [1] Skype on mobile phone -> [2] Skype on server -> [3] plugin to Skype (3rd party application) -> [4] speech recognition Sphinx4. Normally Skype outputs speech to the speaker, normal behaviour of Sphinx4 is to receive speech from microphone. I need to change it so that Skype would redirect its output sound to TCP socket and Sphinx4 would receive it from this TCP socket.

I think this plugin would be server with two children - Skype and Sphinx. I would write this plugin in C#. Can anybody give me, please, any suggestions how to do it? (Examplary codes for other languages than C# would also be useful).


[2] and [3] can easily communicate with each other by sending Skype4COM commands. When the new call is established on Skype (in other words when I call from [1] to [2] and [2] automatically answers this call), plugin [3] enters OurCallStatus function. And inside this function I need to change default output of Skype sound which is set to speakers and make it to be "port".

So there must be Skype -> TCP socket (on localhost) -> Sphinx4. I also thought about other approaches. Those are: IPC (Inter-Process Communication) and maybe some kind of usage of WinAPI.

Why do I have to use TCP socket (Skype -> TCP socket -> Spinx4)? Because I guess it may be impossible or difficult to forward it directly. I need to change this line in code of Sphinx4 application "Microphone microphone = (Microphone) cm.lookup("microphone");" to such a line which would be able to receive speech from "port". I cannot simply save the whole speech from Skype to mp3/wav file and then to open this mp3/wav file in Sphinx4 because it must be done in real time.

Now that you made it all clear all we need to do is to find the right voip phones for this system to work exactly as it's supposed to. I am not very good with source codes but it sure helps knowing more about how to use Skype hardware, I definitely needed that.
