[With Audio] Explaining Indonesian Alphabet Pronunciation!
The important thing when learning Indonesian pronunciation is memorizing the correct sounds.
It is said that Indonesian pronunciation is relatively easy for Japanese people to acquire.
However, once you actually start studying, it can feel difficult because there are sounds not found in Japanese or because the relationship between letters and pronunciation is complex.
In those cases, we recommend actually listening to Indonesian pronunciation.
First, we will introduce the pronunciation of the Indonesian alphabet using audio created with Ondoku.
| Alphabet | Audio | Pronunciation Points |
|---|---|---|
| A | Close to the Japanese "a". Open the mouth vertically. | |
| B | Japanese "ba-line" sounds. | |
| C | "Cha-line" sounds (described later). | |
| D | Japanese "da-line" sounds. | |
| E | Has two types of pronunciation (described later). | |
| F | Pronounce with the lower lip and upper front teeth. | |
| G | Always pronounced as a voiced sound. | |
| H | Japanese "ha-line" sounds. | |
| I | Close to the Japanese "i". | |
| J | Japanese "ja-line" sounds (described later). | |
| K | Japanese "ka-line" sounds. | |
| L | Touch the tip of the tongue to the upper gums. | |
| M | Japanese "ma-line" sounds. | |
| N | Japanese "na-line" sounds. | |
| O | Pronounce with rounded lips. | |
| P | Japanese "pa-line" sounds. | |
| Q | Used only for loanwords. | |
| R | Pronounce with a trilled tongue. | |
| S | Japanese "sa-line" sounds. | |
| T | Japanese "ta-line" sounds. | |
| U | Pronounce with protruding lips. | |
| V | Same pronunciation as F (described later). | |
| W | Japanese "wa-line" sounds. | |
| X | Used only for loanwords. | |
| Y | Japanese "ya-line" sounds. | |
| Z | Japanese "za-line" sounds. |
The key to Indonesian vowels is the two types of "e"! Check the pronunciation with audio.
Next, we will introduce Indonesian pronunciation points that you should definitely memorize!
The first hurdle in studying Indonesian is the pronunciation of "e".
Actually, there are two patterns for the pronunciation of "e" in Indonesian.
1. Clear "e" (é)
This sound is almost exactly the same as the Japanese "e".
2. Ambiguous "e" (ə)
This is the difficult part.
It is a sound not found in Japanese, called "pepet".
The tip for pronunciation is "relaxation".
The key is to keep the mouth half-open and produce a neutral sound that sounds like neither "u" nor "e" when exhaling lightly.
The best way to learn the pronunciation is to actually listen to it!
Let's use Ondoku to compare the pronunciation of words that actually use the two types of "e".
Examples of words using the vowel "é"
| Word | Audio | Meaning |
|---|---|---|
| bela | to protect, to defend | |
| pesta | party |
Examples of words using the vowel "e"
| Word | Audio | Meaning |
|---|---|---|
| semua | all | |
| kemarin | yesterday |
What are the key points of Indonesian diphthongs (ai, au, ei, oi)? Check with audio.
Indonesian has four diphthongs: "ai", "au", "ei", and "oi".
Of these, "ai", "au", and "oi" are the three that commonly appear in daily life.
The tip for pronunciation is not to cut corners midway!
While the Japanese "ai" often becomes ambiguous, in Indonesian, each vowel is pronounced clearly until the end.
Let's listen to the audio created with Ondoku and compare.
Examples of words using the diphthong "ai"
| Word | Audio | Meaning |
|---|---|---|
| ramai | lively/crowded | |
| damai | peaceful |
Examples of words using the diphthong "au"
| Word | Audio | Meaning |
|---|---|---|
| atau | or | |
| pisau | knife |
Examples of words using the diphthong "oi"
| Word | Audio | Meaning |
|---|---|---|
| koboi | cowboy | |
| boikot | boycott |
What consonant pronunciations should you be especially careful with in Indonesian?
Next, we will explain the pronunciations that Japanese people should be particularly careful with when learning Indonesian.
Caution: Indonesian consonants "c" and "j" have different pronunciations than in English.
When studying Indonesian, the consonants you should be especially careful with regarding pronunciation are "c" and "j".
Do not read "c" and "j" with English pronunciation.
If you read the Indonesian "c" with English pronunciation as "s" or "k", you won't be understood at all.
Let's listen to the audio created with Ondoku and compare.
Examples of words using the consonant "c"
| Word | Audio | Meaning |
|---|---|---|
| cuaca | weather | |
| cantik | beautiful |
Examples of words using the consonant "j"
| Word | Audio | Meaning |
|---|---|---|
| juga | also/too | |
| jadi | so/therefore, to become |
In Indonesian, the consonants "f" and "v" have the same pronunciation.
Also, a point of difference from English is that in Indonesian, the consonants "f" and "v" have the same pronunciation.
The pronunciation of the consonant "v" is exactly the same as "f", pronounced using the lower lip and upper front teeth.
However, whether to use the consonant "v" or "f" depends on the word, so you need to memorize them individually.
Examples of words using the consonant "f"
| Word | Audio | Meaning |
|---|---|---|
| foto | photo | |
| fakta | fact |
Examples of words using the consonant "v"
| Word | Audio | Meaning |
|---|---|---|
| variasi | variation | |
| aktivitas | activity |
