What dictates how new words should be pronounced? [closed]

Solution 1:

What dictates how new words should be pronounced?

Usage. But really, there is no "should" in English. There is "accepted", "popular", "UK", but there is no "should". The inventor of a word has zero authority over it. So being new isn't really relevant.

As the word get's used people will pronounce it as they think best. Different ways to pronounce the word will compete. Wars could be fought over how to pronounce it but there still would be no authority. The spoken word is a fluid thing. Nailing it down is like nailing jello to a wall.

There are pronunciation guides. Do not mistake these for authority. If a biologist hands you a book that explains how fish swim don't think the book controls how fish swim. At most, it may give you ideas on how you might swim.
