ABSTRACT
This chapter elaborates on the ontological properties and situational analysis of the illocutionary force types. Based on the self-constructed corpus and collected data, statistical techniques were utilized to analyse the multimodal resources presented in all the tokens of illocutionary force. Apart from this, this chapter analyses the influence factor of the live speech acts and illocutionary force indicating devices (IFIDs) in situated discourse. These steps are covered: (1) summing up the live speech acts and IFIDs in the self-constructed multimodal corpus, including language structure, prosodic features and gestures, and to analyse their functions; (2) calculating the frequencies of all the recorded multimodal cues and their underlying meanings and then to conclude the regular patterns of emergence and concurrence of emotions and prosodic features and gestures in the four classes of illocutionary force; and (3) deducing the influence factors of live speech acts and IFIDs.
