Therefore, the assimilation occurred because the participants did not perceive those sounds as distinctive sounds.
The sound good [g
ʊd] to become [gʊt], allows the final devoicing of voiced alveolar stop d into t. In Indonesian sound system, voiced alveolar stop
d is allophonic to voiceless alveolar stop t if it is occurred in the end of the
word. This change was caused by inappropriate analogy. The participants might have been accustomed to the allophonic sounds in the end of the word of their
native language and then applied it in pronouncing the target language. The word change
[tʃeɪndʒ] to be [tʃens] stimulated the final devoicing of
voiced palatal affricates
dʒ into voiceless alveolar fricative s. In Indonesian
language sound system, such affricates do not exist in the end of the word Yulia Ena, 2004. The participants then substituted the palatal sounds into alveolar
sound s, which is more familiar in Indonesian language sound system.
7. Abnormal Sound Changes
Crowley 1992 state other sound changes that do not obviously fit into any categories are included into abnormal sound changes. In this research, the
researcher found three cases of abnormal sound changes that did not fit into any categories. Those three sound changes involved one vowel sound change and two
consonantal sound changes. For the complete information, the researcher had listed the classification of words affected by abnormal sound changes in the Table

The first change was the shift of low front vowel [æ] into mid front vowel [e]. The shift from the former vowel into the latter vowel occurred in both front
and middle of the word. The sound change in front of the word can be seen in
word accurate [æ k.jʊ.rət]. The participants tended to pronounce [ek.jʊ.rət] which
