Social speech: voice, prosody, and formulaic language. Naturalistic speech utilizes elements that were not in focus in traditional linguistic studies, but have recently emerged as extremely important to descriptions of human verbal communication. Using capacities of the voice, an array of nuances, meanings, and intentions contributes mightily to conversational interaction. Although these prosodic signals still elude full and detailed description, they can be described in broad outline. Related to the configurations of prosody are the formulaic expressions that are so prevalent in discourse. These are conversational speech formulas (“how’s it going?”), expletives, idioms, and other unitary expressions known to the native speaker in terms of their words, prosodic shape, contextual meanings, and conditions of use in the social setting. Depending on speakers, social register, and theme, about 25% of talk consists of formulaic language. Second language speakers famously err in use of prosody and formulaic expressions. For example, the expression “I wouldn’t want to be in his shoes,” to sound native, must have the sentence accent on “his.” Brain damage interferes selectively with native sounding prosody and formulaic expression usage. Current studies of the important roles of voice, prosody, and formulaic language in naturalistic speech, and the effects of brain damage on these communicative elements, will be reviewed, with several themes presented for discussion.
