Google Chrome provide speech to text(STT) and So many smart phone apps provide STT. It has good recognition.
I want program in Visual Studio(MFC), But there's no methods to do STT. If I use Google Speech To Text Api, It's so easy to settle this problem.
If there's no public google api about STT, Tell me another way to this except with start.

To my knowledge, Google has not documented their speech API and do not intend it to be used by general purpose clients. I believe their intent is for the speech API to support their Android and Chrome products. That said, there is more information at Does Anyone Uses Google Speech API in Production? and Is there an API for Google's speech recognition technology?.
Since you're programming for Windows, why don't you use the built in Windows speech engine. You can use the System.Speech features of .Net or Microsoft.Speech and install the free recognizers Microsoft provides. Windows 7 includes a full speech engine. Others are downloadable for free. There is a C++ API to the same engines known as SAPI. See at http://msdn.microsoft.com/en-us/magazine/cc163663.aspx. or http://msdn.microsoft.com/en-us/library/ms723627(v=vs.85).aspx. More background on Microsoft engines for Windows What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?
One last link that I hope is helpful, here is a simple example of speech recogntion in .NET - SAPI and Windows 7 Problem

You may find this: https://gist.github.com/alotaiba/1730160 useful. Basically you need to send FLAC-encoded audio file to google servers in POST request. Be aware that it accept only audio files of 15 seconds of less (for simple voice command app it would be enough).
I'm looking into thing like this and MS Speech API isn't for me, even if is good, because it doesn't support most languages Google's API does (example being Polish, same for MS text-to-speech).
