We would ask the question this way. "How do I talk to other people?" It's probably more common to ask, "How do I start a conversation with other people?" To BEGIN a question with "how to..." is Chinglish, although we can say " 'Please tell me how to start a conversation with others" or "I don't know how to talk to others." However, there's an exception. It's correct to say, for example, "How to learn English effectively is a problem for many students."
