How do you translate the word 'aloud' in the following sentences?

- I like to speak Russian aloud.
My guess is "Я люблю говорить по-русски вслух".
- I want you to read the book aloud.
My guess is "Я хочу, чтобы ты прочитала книгу мне вслух".

If these guesses are correct, when do we use "громко"? Can someone give me a few examples?
