Need libraries for compare speech tracks (pronunciation)

There are two speech sample (in wav or mp3). Need to compare both 开发者_开发问答and set some coeff of comparing.

It's need to training pronunciation like Rosetta Stone.

Prefer libs for .net.

Start with the System.Speech libraries in the .NET Framework: http://msdn.microsoft.com/en-us/library/gg145021.aspx

This page shows how to use Synthesis to speak words, and Recognition to listen and recognize what a user is saying: http://www.mperfect.net/speechSamples/
