Phonetic characteristics in the announcement over a PA system in high-school baseball

Abstract

The purpose of this paper is to describe the phonetic characteristics in the announcement over a PA system in high-school baseball. Survey subjects are females who currently make announcements over a PA system. The following characteristics were observed as a result. (1) A pause is phrase-based, and a rising-tone is often observed at the beginning of the phrase. Such rising tone at the beginning of the phrase has a higher degree of change than regular speech. (2) A pause during speech lasts for 435.6ms on average, consisting of 20.2% of overall speech. (3) The rate of speech is slower in the case of an announcement over a PA system in a stadium than that of regular speech.
