Javascript library to determine indefinite article

Question

Are there any javascript libraries that exist for determining the indefinite article ("a" vs "an") of a noun?

I can start with a simple regex like so:

var pattern = /^([aeiou])/i;
pattern.test("umbrella");

but this doesn't handle a case like: "user" which should return false (you wouldn't say "an user clicked the button").

The following Javascript library by Eamon Nerbonne should be what you are looking for:

This was actually created as an answer to a similar question here on SO:

The approach used here was to download Wikipedia, filter it, and create a prefix database to determine a/an, which should be more accurate than most rules-based systems. You can find more information at the following location (also linked in the above answer):

There is also a link there to an alternative implementation by Chad Kirby:
