The Deseret language is a very unique alphabet system based on phonetics. It was developed by Brigham Young, an LDS prophet after Joseph Smith, to replace the Latin alphabet with a more accurate phonetic system. Here is a snippet from Joshua Erickson’s Deseret Alphabet Pages:
In the mid 1800’s, Brigham Young, the Mormon prophet, saw a need to reform the English language with all its marvelous inconsistencies; therefore, he commissioned the development of a new alphabet. When it was finished, and even before it was finished (because it went through several revisions), they called it the Deseret Alphabet. It is a phonetic alphabet, and its development was strongly influenced by the work of Isaac Pitman. The LDS Church used the new alphabet to publish scores of newspaper articles, three children’s readers, the Book of Mormon, and a few other items. Manuscripts were also prepared for the Bible, the Doctrine & Covenants (including the Lectures on Faith), the Pearl of Great Price, and other books. Unfortunately, none of these were ever put into print.
