Unity Speech Recognition C# dictionary problem

I want to successfully implement an advanced speech recognition system that can know what to do if you speak a phrase of 2 or 3 actions like "GO FORWARD and CHANGE COLOR TO GREEN and then TURN TO THE LEFT". I've implemented a dictionary:

private Dictionary<string, Action[]> actions = new Dictionary<string, Action[]>();

and by now I added some words in it:

actions.Add("up", new Action[] { Up });
actions.Add("down", new Action[] { Down });
actions.Add("left", new Action[] { Left });
actions.Add("right", new Action[] { Right });
actions.Add("green", new Action[] { () => ChangeColor(this.word) });
actions.Add("red", new Action[] { () => ChangeColor(this.word) });
actions.Add("white", new Action[] { () => ChangeColor(this.word) });
actions.Add("blue", new Action[] { () => ChangeColor(this.word) });
actions.Add("yellow", new Action[] { () => ChangeColor(this.word) });

But then I thought...

I want to have advanced speech recognition, so I think (and I hope!) there is a better way than adding lots and lots of combinations of words in this dictionary.

So can you help me? Do you know if there is a better way? Because it would be very unpleasant and boring and it would take a long long time to get in the dictionary what you want. Even for changing color, I can think now at: change color to green, change to green, change your color to green, make green your color, make green your new color, etc.

To help you to code easier, you could use this method:

so using enum to list your command and inject automatically in the Recognizer. the advantage of this method : if you add new commands no big modification in your code, just add new funtionality.. so i think the program is more readable.

public class TestPrg : MonoBehaviour
{
    private enum Commands
    {
        Up = 0, Forward, Left, Right,//first group
        Green, Blue, Red,            //second group
        Other, Other1                //third group....
    }

    private KeywordRecognizer kr; 

    void Start()
    {
        //Transform Enum Commands to string[]    
        kr = new KeywordRecognizer(Enum.GetNames(typeof(Commands)));

        kr.OnPhraseRecognized += RecognizedSpeech;
        kr.Start();
    }


    private void RecognizedSpeech(PhraseRecognizedEventArgs speech)
    {
        Commands cmd;
        if (Enum.TryParse(speech.text, true, out cmd))
        {
            ActionCmd(cmd);
        }
    }

    private void ActionCmd(Commands cmd)
    {
        if (cmd >= Commands.Up && cmd <= Commands.Right)
        {
            Move(cmd);
        }
        else if (cmd >= Commands.Green && cmd <= Commands.Red)
        {
            ChangeColor(cmd);
        }
        else
        {
                //Othercommand();
        }
    }

    void Move(Commands cmd)
    {
        switch (cmd)
        {
            case Commands.Up:
                //action
                break;
            case Commands.Forward:
                //action
                break;
            default:
                break;
        }
    }

    private void ChangeColor(Commands cmd)
    {
        switch (cmd)
        {
            case Commands.Green:
                //action
                break;
            case Commands.Blue:
                //action
                break;
            default:
                break;
        }
    }
}
