FPS weapon switch to audio instead?

Unity Engine
1

i’ve been using the scripts from FPS tutorial which have been totally great!!!

but how can i switch from weapon1 to audio instead of to weapon2?

ie:
press 1 for weapon
press 2 for audio (ie. player voice)

this is the code:

function Start () {
	// Select the first weapon
	SelectWeapon(0);
}

function Update () {
	// Did the user press fire?
	if (Input.GetButton ("Fire1"))
		BroadcastMessage("Fire");
	
	if (Input.GetKeyDown("1")) {
		SelectWeapon(0);
	}	
	else if (Input.GetKeyDown("2")) {
		SelectWeapon(1);
	}	
}

function SelectWeapon (index : int) {
	for (var i=0;i<transform.childCount;i++)	{
		// Activate the selected weapon
		if (i == index)
			transform.GetChild(i).gameObject.SetActiveRecursively(true);
		// Deactivate all other weapons
		else
			transform.GetChild(i).gameObject.SetActiveRecursively(false);
	}
}

thanks alot!
would be grateful for any ideas!

   audio.Play();
