Build speech recognition speech conversion into text on screen computer

I need you to develop software for me. I would like this software to be written in Visual studio for windows. The creator must write speech recognition in Polish so that what is said appears on the computer screen The creator can do the way he wants, whether by recording wav and converting to text, the way the performance is done. Speech recognition must be in Polish ----------------------------------------------------------------------------------------------- How a program should work ? when it is on should wait for a word that causes speech recognition, for example "John" -> wake up keyword example: Jan -> Now im saying in polish language ------------------------------------------------------------------------------------------- Do not bid if you are not sure that you can do recognition in Polish The object will then be developed further so after a good completion of this task I will want to cooperate with the creator over my other projects
