Interpreters are public speakers. They spend an enormous amount of time speaking during their professional life. Therefore their speech behaviour is an essential component of their communication and professional behaviour. This paper discusses the main characteristics of human speech with a special focus on continuous speech and its prosodic features such as stress, intonation, speed and voice quality. It also deals with the topic of speech behaviour in general as well as with voice health and voice hygiene, voice and identity, the role of breathing during speaking and the function of the human speech apparatus in voice production in particular. Finally it characterises the speech behaviour of professional interpreters and the factors influencing the paralinguistic features of their speech.
