What is the difference between speak and talk?

Speak is more formal and often one-directional (speak a language, speak to an audience). Talk is more casual and implies two-way conversation (talk to a friend, talk about something).

Do you say 'speak with' or 'talk with'?

Both are correct. 'Speak with' is more formal, while 'talk with' is more casual. 'Talk to' is more common than 'speak to' in everyday conversation.
