The System.Speech.Recognition namespace contains Windows Desktop Speech technology types for implementing speech recognition. Its part of the .NET Framework.

The Windows Desktop Speech Technology software offers a basic speech recognition infrastructure that digitizes acoustical signals, and recovers words and speech elements from audio input.

Applications use the System.Speech.Recognition namespace to access and extend this basic speech recognition technology by defining algorithms for identifying and acting on specific phrases or word patterns, and by managing the runtime behavior of this speech infrastructure.
