Final answer:
Formal speech exchange systems are characterized by fixed turn length, order, and content. This systematic structure is observed in formal settings and interviews, ensuring consistency and adherence to formalities. Vocal delivery and the use of rhetorical devices in language play a crucial role in connecting with the audience. Therefore correct option is (1)
Step-by-step explanation:
The characteristics of formal speech exchange systems are best described by the statement that turn length, order, and content are fixed. This structure is often seen in formal settings such as judicial proceedings and legislative sessions, where the rules of engagement are clearly defined and typically followed. Each speaker's turn is usually predefined in terms of who speaks when, for how long, and what subject matter is allowed to be addressed. This contrasts with informal speech exchanges, where these elements are more flexible and can vary widely depending on the context.
For example, in a formal interview, questions and their order remain the same for every participant. This ensures a systematic approach and consistency in the way information is collected and presented. Moreover, the reliance on specific language constructs, including rhetorical devices, represents the purpose, culture, or audience expectations within a given speech or writing context. The verbal delivery relies not only on the choice of words but also on vocal delivery, which includes tone and inflection, to establish a connection with the audience.
