How to edit custom spelling dictionaries? Is it possible to extract the custom user spelling dictionaries from a rooted Android 4.0 phone? The built-in dictionary really sucks for languages other than English and I'd like to complement it with a few thousand more words.
User Dictionary Manager might be what you are looking for.

From the description:


  UDM is an application that allows you to
  edit/export/import/delete/clean the user dictionary words found on
  your Android phone.
