You can change on the settings to expert commands instead of normal. I did that and it understood me better.
I believe you can "educate" the voice recognition by going into the Setup Screen and selecting Voice Recognition. I haven't needed to do this, but I believe it does give you some specific words to repeat and better adjust the voice recognition to your specific voice.Is there a voice recognition that i can do that i repeat the words to it so it can learn my voice????...btw I don't have a accent..
