Speakers also produce sounds that have no real meaning, such as laughing, coughing, swallowing etc. . These are all labelled as <Ger"ausch> (German for noise). If one of these noises occurs for a longer period of time, without being interrupted (a speaker laughing for example), a single label will be sufficient. As usual, punctuation marks come first.
