firstly, Hi. in fact, it is the difference between 朗and 诵, 诵seldomly used alone, often seen in 朗诵or 诵读, which mean read it out, and loudly, with emotions. As long as 诵appears, it's very literary, for example a poem, or a piece of classic literature, and often used in a very formal situation, like a poem reading contest. 读is very coomonly used, you can use it as a single word,or 朗读, and they are very similar, it's just that with 朗读, you have to read it out, often very loudly, for example, a student朗读 sth in front of the entire class. while读，it has nothing to do with sound per se, maybe silently reading a book or maybe read it out. when you don't know what to say or doing a Chinese exam or writing, 读is the security choice, hehe! and 诵 alone is absolutely wrong. and when you want to emphasize that it is read OUT, that's 朗读， good luck!

诵读 means reciting,and 朗读 only means read aloud.诵can't be used as a word.But 读can.读can means read without voices.

诵means 'recite' 读means ‘read'(read out, not in silence) (read a book in silence means '看书') 诵读 recite from memory 朗读 read with sentiment (you can look at the paper) 诵读 /朗读 is specifically used in the class when a student is asked to recite/read（诵读 /朗读） an article loudly to the whole class。

诵读多用于文言文、古文、古诗 朗读可用范围更广，不仅包括文言文、古文和古诗，也包括其他各种文字。 这两个词都表示严肃的念出文字。

诵读 means that you read loudly without books.u have recited it. 朗读 means u read loudly with a book in ur hand. u haven't recited it and u need to read with ur emotion.
