Application Speakable Items folder vs. Scripts f.

A question from a novice scripter:
I wish all AppleScripts (those already created and those I will create) to be speakable. And there are OS structures/mechanisms - the User/Library/Speech/Speakable Items (and its Application Speakable Items subfolder) and the make application speakable script - that encourage this.
As I understand it only the scripts in that Speakable Items folder are recognized by the Speech system.
Yet the main scripts folder is User/Library/Scripts, and that is the one that appears in the OS X menu bar.
Why the dichotomy, and how best to reconcile the two folders so that indeed the scripts in the Scripts folder are also speakable and that new scripts that are intended to be spoken also appear in the scripts menu??
