Do You Read 'Aloud' or 'Out Loud'?
Out loud may sound unpolished, but it's a fine substitute for aloud
For a long time, writers were told to avoid the phrase out loud. It was an error, they were told, for the firmly-established aloud, which has been a word in English since the 13th century. In contrast, out loud was a relative newcomer: it only dates back to the beginning of the 19th century.
Lord Andover in the presence of Lord and Lady Suffolk and speaking out loud said "Miss Dutton ... be so good to walk with me into the library."
—Maria Edgeworth, letter, 1821
Even if out loud was a word, language commenters commented, it was a colloquialism—an informal or conversational word you might use with your friends, but should avoid in formal writing.
Usage today, however, shows clearly that out loud is not a colloquialism and that—although we would agree that aloud is more likely used in solemn writing—in general the two terms are essentially interchangeable.
For many of us, one of the most vivid memories from childhood is listening to Mom reading a book out loud or telling a story.

There are even some cases in which out loud is the preferred term. A distinctive and exclusive use of out loud is in the idiom for crying out loud. Most sources explain the expression as the result of finessing one's way out of saying the inappropriate just as it's practically out: "For Chri—ying out loud!"
It's just a big old sack of dog food, for crying out loud, but Charles Fishman can hardly restrain himself: "Fifty pounds for $13.82! That's amazing!"

Out loud also one-ups aloud as the preferred word following the verb laugh.

However, don't be surprised if you spy aloud in company with laugh. For instance, in Roald Dahl's James and the Giant Peach, James "had never heard Aunt Sponge or Aunt Spiker laughing aloud in all the time he had been with them." Such occurrences show that using aloud or out loud is entirely a writer's choice. That choice might hinge on the tone of the writing—whether it's formal or colloquial—or it might involve something deeper. Perhaps the writer sees aloud as being the only choice because of its long-standing establishment in the language and sees out loud as a newcomer yet to prove its mettle.
