The book is the first to apply David Brazil’s Discourse Intonation systems (prominence, tone, key and termination) to the study of a corpus of authentic, naturally-occurring spoken discourses. The Hong Kong Corpus of Spoken English (prosodic) is made up of approximately one million words consisting of four sub-corpora of equal size, namely academic, conversation, business and public. The participants are all adults and typically have either Cantonese or English as their first language. The four Discourse Intonation systems are described in terms of how the system works and how they are manifested in the corpus, both across the sub-corpora and also across speakers in the corpus. The book is accompanied with a CD containing the prosodically transcribed corpus together with iConc which is the software designed and written specifically to interrogate the HKCSE (prosodic). The issues raised and discussed are all of importance in Conversation Analysis, Corpus Linguistics, Discourse Analysis, Discourse Intonation, Pragmatics, and Intercultural Communication.
