Spoken out loud.
"The teacher asked students to read their essays aloud so everyone could hear them clearly."
With a loud voice, or great noise; loudly; audibly.
"She read the story aloud so that everyone in the room could hear every word clearly."
In plain English: To speak aloud means to say something out loud so that other people can hear it instead of whispering inside your head.
"She read the story aloud to her children before bed."
Usage: Use aloud to indicate that speech is spoken with enough volume to be heard by others, distinguishing it from speaking silently in one's head. This adverb typically follows the verb directly, as in "read aloud," rather than appearing before it like an adjective would.
The word comes from the phrase a-loude, which literally means "in a loud sound." It entered Old and then Middle English as an intensifier meaning specifically with audible volume.
