Answer 1

Most probably you are using Microsoft.Speech.Recognition and you reall should be using System.Speech.Recognition.

Change this:

using Microsoft.Speech.Recognition;

to this:

using System.Speech.Recognition;

You can leave the rest of the code as it is.

Wh? Well here are some answers: What is the difference between System.Speech.Recognition and Microsoft.Speech.Recognition?

In short Microsoft.Speech.Recognition is for servers and works with low quality audio like you find in call centres (used for automation etc.), this means it is not compatible with all audio input devices.

On contrary System.Speech.Recognition is for Desktop apps and it fully supports default recording devices installed on Windows.
