In conversations, openers and fillers are used quite often. They don't always have specific meanings. Openers are used as signals that you are about to say something, or to smooth communication. Fillers are usually used for pauses or hesitation. English also has similar expressions such as "so," "like," "you know," and so on. When you have opportunity to hear native speakers' conversation, listen carefully and examine how and when they are used. Here are some openers and fillers frequently used.
