Isochronism of Feet in English Fixed Meter on Moraic Analysis and Durational Measurement in Reading

모라 분석과 낭송 측정에 의한 영시 정형률의 음보 등시성

This study aims to define the isochronism of English feet. To assess the average value of moras of a foot, the study is, first, to set up a way of counting the number of the moras on the extrametricality with some modifications. Secondly, with the measurement of the average duration of feet of Shakespeare's 120 sonnets through Praat (version 4.030, 2002), it clarifies the foot isochronism in English. With the two ways of measuring the isochronism, it clarifies the fact the foot isochronism permits the difference scope of $2.2{\mu}'s$ (moras) to $1.8{\mu}'s$, that is, $22{\mu}'s$ to $18{\mu}'s$ per line, while the acoustic assessment shows the isochronically congnitive gap of 302-447msec. per foot, or 4,461msec. to 3,019msec. per line in case of iambic pentameter in English poetry.
