How to implement voice recognition in .NET?

I've got a bunch of .mp3s with a computer-generated voice of relatively high quality. In each .mp3 the voice says some random text and then a sequence of 6-7 digits in English. I'd like to extract those digits as text.

Is it possible to implement such a thing in .NET?

Speech is one of the most fundamental ways to interact. When it gets to computers it is no different. If an application can be controlled only by way of voice commands then the opportunity that lies is unlimited. Even though the idea of using speech as an input mechanism for an application is not new there are not a lot of applications that use speech as input. In other words, speech is still a big opportunity that is yet to be explored.

Speech recognition can be of two types which are based on the grammar that the recognition is based on. (Grammar is, in other words, the list of desirable recognition outputs that can be generated.) An application can limit the possible combination of the words spoken by choosing proper grammar.
