Abstract
This study examined the communicator's speech production process in order to identify uniqueness of his/her speech behavior. Communication participation style was set as the predictor of speech behavior, while sociometric status and the intragroup composition of members served as moderator variables. Experiments involving small-group discussions were conducted to see how factors inherent in interpersonal situations play upon the hypothetical associations between each factors of communication participation styles, and the speaker's speech behaviors. Results indicated that sociometiric status was not a moderator, but an independent variable influencing speech frequency. These findings support the Speaker-Role hypothesis, but a reconception of the speech production process model was mandated.
