Hey Danyel, how are you? I hope you are doing just fine!
I should tell you that all of these expressions mean the same thing:
1) 'Read (something) out' = it means 'to read something aloud'.
E.g.: ''Please read it out so everyone can hear you.''
E.g.: ''She read out the names loudly.''
2) 'Read (something) aloud' = to read something in a loud voice so that other people can hear you.
E.g.: ''I was obliged to read the letter aloud.''
E.g.: ''He read aloud to us from the newspaper.''
3) 'Read (something) out loud' = it means 'to read something audibly/aloud''.
E.g.: ''I sometimes find myself reading the paper out loud.''
E.g.: ''Shall I stop reading this poem out loud?''
Hope that helps!!! :)
