Greetings.Is there any way to modify simple electret microphone so he can be used as directional microphone? I can use both hardware and software filtering.Microphone will be used for speech recognition.Distance from sound source should be between 3-10 feet.So, what do you think?

Put it at the focus of a parabolic reflector. There is nothing you can do to the electrical signal to make a single microphone directional.
