An experimental study of the role of tone of voice in Japanese conversations, using both Japanese and American subjects, has uncovered situational determinants of voice quality not related to emotion. Some of these variations are perceived differently by the two sets of subjects, some in the same way. The nature of the situational determinants casts new doubt on the plausibility of ‘language’ as a natural subset of human communications. (Tone of voice, non-linguistic communication, ethnography of communication, Japan.)

Stylistic analysis takes account of the dynamic continuities in communication behavior. It is concerned with how people talk or sing or move in relation to each other, rather than what it is they say or sing or do to or with each other. The presence of these styling qualities can, we discover, be reliably assessed; and, as they cluster together, giving each cultural tradition its distinctive performance models, they have remarkable stability through time. However, these patterns of style are not inflexible: they are models comprising a stable set of ranges within which performers can adjust their behavior to the demands of a genre, of a familiar situation, of sex, age or status roles, and to the unexpected. The comparison of these performance models, cross-culturally, reveals factors that tie communication to social structure on the one hand and to cultural traditions on the other.
