Question

2. He said to himself, "How can I send e-mails on the Internet?"

3. He spoke to himself, "How can I send e-mails on the Internet?"

Are all the expressions correct? Which one is commonly used? Say to, talk to, or speak to? Are they the same?

Answer 1

All 3 are grammatically correct but #2 is said most often. OR "He asked himself....."

Answer 2

Most commonly, 2 is used (said). I think that 1 and 3 sound funny. I think you need different punctuation or sentence structuring in order to have them make sense.
