Accuracy of EasyVR shield

Hello there,
I am going to start a project using voice recognition. I want to use EasyVR 3.0 . But I am a little bit confused that it will recognise voice from the different person? I want to know it's accuracy.

Is there any easy tutorial to better understand serial communication?

Hi, and welcome to the forum.
The (free) EasyVR Commander software has five "Strictness" levels.
On level four I can get it to recognize >90% of my trained commands, while ignoring other people.
Think of it as an interesting toy that could take many hours to get right.
I use the shield version, and did not have any problems with serial.
Don't start this project, unless you're an advanced coder.
The bundled Arduino example is a beginners nightmare.

Hi, I have done some projects. But day by day decreasing its accuracy. Now it is taking random command while nothing has said. But during providing command it takes correct command. Whenever the first word is similar for multiple commands causes an error.
