Chapter 4 contains extensive references to exemplifications of the voice quality categories described in Chapters 1 and 2. Distinctive voice quality settings of actors, singers, media announcers, politicians, and other personalities are cited with specific references to be used as search terms to locate video and audio material online. A separate ‘Multimedia References’ section is included at the end of the text to facilitate searching. Long-term voice qualities are essentially extralinguistic, but they can also alternate among phrases of speech as paralinguistic ‘registers’. Many laryngeal postures, and their auditory output, are employed linguistically as syllabic registers or segmental units to signal contrastive lexical meaning. This is a result of the positioning of the laryngeal articulator at the beginning of the shaping of the sound stream, where background elements are easily patterned behind oral articulations. Extensive references to linguistic examples of lower-vocal-tract consonantal strictures and tonal register effects are presented within the text notes and are included among the video and audio materials online.
