Pronunciation Rules in Indonesian

Overview

Indonesian pronunciation is relatively straightforward thanks to its phonetic spelling system. However, there are several key rules that differ from English pronunciation habits. The most important is the distinction between two types of "e" sound: e pepet [ə] (a schwa, like the "a" in "about") and e taling [e] (like "eh" in "bed"). Unfortunately, both are written simply as "e."

Other important pronunciation features include consonant digraphs (ng, ny, sy, kh), the trilled "r," and the glottal stop that sometimes replaces a final "k." Stress typically falls on the penultimate syllable, though prefixes can shift the stress pattern.

How It Works

The Two E Sounds

Type	Sound	Example	Meaning
e pepet [ə]	schwa, like "a" in "about"	belajar [bəlajar]	to study
e taling [e]	like "eh" in "bed"	enak [enak]	delicious

Consonant Digraphs

Digraph	Sound	Example	Meaning
ng	[ŋ] as in "sing"	dengan [dəŋan]	with
ngg	[ŋg] as in "finger"	tanggal [taŋgal]	date
ny	[ɲ] as in "canyon"	nyamuk [ɲamuk]	mosquito
sy	[ʃ] as in "she"	syarat [ʃarat]	requirement
kh	[x] as in "Bach"	khawatir [xawatir]	worried

Consonant Pronunciation

Letter	Sound	Note
c	[tʃ] "ch"	Always like "church"
g	[g] hard	Always like "go," never like "gem"
h	[h] or silent	Sometimes silent between vowels
k	[k] or [ʔ]	Can be a glottal stop at end of word
r	[r] trilled	Trilled or tapped, not English "r"

Stress Rules

Rule	Example	Stress Pattern
Penultimate syllable	selamat	se-LA-mat
With prefix, stress shifts	me-nu-lis	me-NU-lis
Final closed syllable	Sometimes final	varies

Common Mistakes

Pronouncing C as "k" or "s"

• Wrong: cari as "kari" or "sari"
• Right: cari = [tʃari], like "chari"
• Why: C in Indonesian is always pronounced "ch," without exception.

Not distinguishing ng from ngg

• Wrong: Pronouncing dengan and tanggal with the same nasal
• Right: dengan [dəŋan] has ng [ŋ]; tanggal [taŋgal] has ngg [ŋg]
• Why: ng is a pure nasal; ngg has the nasal followed by a hard g.

Using English "r"

• Wrong: Pronouncing rumah with an English approximant "r"
• Right: Trill or tap the "r" as in Spanish or Italian
• Why: Indonesian r is a dental trill or tap, quite different from the English r.

Practice Tips

1. Practice the two "e" sounds with word pairs. Say belajar (schwa e) and enak (open e) back to back until you can feel the difference. Listening to native speakers is invaluable here.
2. Practice the ng sound at the beginning of words — this is unusual for English speakers. Start with ngaruh (influence), ngomong (speak), ngantuk (sleepy).
