Figure 5.1 The Formula for Calculating Sound Change Distribution
The result showed that the most frequent sound change occured in participants’ pronounciation was lenition and fortition found in 23 cases with the
percentage of 47,9 . They included 7 cases of lenition, 4 cases of syncope, 5 cases of cluster reduction, and 7 cases of fortition with the percentage of each
14.6, 8.3, 10.4, and 14.6. The second frequent types of sound change was abnormal sound change. This type of change underwent 14 cases with the
percentage of 29.2. The third place was assimilation sound change which underwent 4 cases with the percentage of 8.3. The following order were placed
by fusion, unpacking, and vowel breaking which underwent 2 cases for each of them and with the percentage of 4.2 for each. The last one was sound addition
which underwent only 1 case with the percentage of 2.0. Table 4.9 showed the distribution of English sound change among the
students in this research. The result showed that the most frequent sound change occured in
students’ pronounciation was lenition and fortition with 23 cases and the percentage of 47,9 . They included 7 cases of lenition, 4 cases of syncope, 5
cases of cluster reduction, and 7 cases of fortition with the percentage of each
59
14.6, 8.3, 10.4, and 14.6. Lenition sound change included the substitution of stronger sounds into weaker sounds such as [æ] [
ə], [ɒ] [ʌ], [a:] [ʌ], [z]
[s], [θ] [t], [f] [p], [ð] [t]. The syncope included the loss of vowles [a] and [ɪ] in the middle of the words. Cluster reduction included the deletion of the
sound [t], [g], and [d]. Fortition included the substitution of weaker to stronger sound such as [
ə] [ʊ], [ə] [o], [ə] [a], [ə] [ɪ], [ʌ] [e], [ʌ] [o], and [ɜ] [o].
The second type of sound change was sound addition specifically ephenthesis with 1 case and the percantage of 2.1 . They were the addition of
vowel [e] and [ ə] in a middle of cluster consonants.
Third type was fusion with 2 cases and the percentage of 4.2 . These two cases were the blending of [
ə] and [ʊ] sound became [o] sound, and [a] and [ʊ] sound became [e] sound.
Fourth type of sound change was unpacking with 2 cases and the percentage of 4.2 . They were the change of [ɒ] sound into [a] and [ʊ] sounds,
and [ɜ] sound into [e] and [ ə] sound.
The fifth type was vowel breaking with two cases and the percentage of 4.2 . The examples was the change of [
ə] sound became [eɪ], and [i] became [aɪ] sound.
The sixth type was the process of assimilation which underwent 4 cases with the percentage of 8.3. The examples were the palatalization of [s] became
60
[ʃ] sound, and final devoicing as happened in [z] [s], [d] [t], and [v] f] sound.
The last type of sound change found in this research was abnormal sound change. This type of change underwent 14 cases with the percentage of 29.2 .
The examples were consonant addition such as [r] in the middle of vowels in a word, abnormal change that occured in the deletion of almost a half of the sound
in a word, syllable reduction as happened in the reduction of [ɪz] and [ɪd] syllable at the end of the word, palatal to alveolar change such as [ʃ] [s] and [ʤ] [d],
interdental to alveolar change such as [ð] [d], low to mid change such as [a] [e], and [a] [o], high to mid change such as [ɪ] [e], lax to tense change such
as [ɪ] [e] and [ɪ] [i], back to front change such as [a] [e].
