[Audio included] Explaining the pronunciation of the Indonesian alphabet!

When learning Indonesian pronunciation, it is important to remember the correct pronunciation .
Indonesian pronunciation is said to be relatively easy for Japanese people to learn.
However, when you actually start studying it, you may find it difficult because there are sounds that don't exist in Japanese and the relationship between letters and pronunciation is complex .
In such cases, we recommend that you actually listen to the Indonesian pronunciation .
First, we will introduce the pronunciation of the Indonesian alphabet using audio created with "Ondoku."
| alphabet | audio | Pronunciation points |
|---|---|---|
| A | It's similar to the Japanese "a." Open your mouth vertically. | |
| B | Japanese "ba" row | |

The key to Indonesian vowels is the two types of "e"! Check your pronunciation with audio

Next, we will introduce some important Indonesian pronunciation tips that you should definitely remember!
The first thing you may struggle with when learning Indonesian is the pronunciation of the letter "e."
In fact, there are two ways to pronounce the Indonesian letter "e."
1. A clear "é"
It sounds almost the same as the Japanese "e".
2. The vague "e" (ə)
This is the difficult point.
It has a sound that does not exist in Japanese and is called "Pepetto."
The trick to pronunciation is to relax .
The key is to keep your mouth half open and exhale lightly to make a neutral sound that sounds neither like "uh" nor "eh."
The best way to learn pronunciation is to actually listen to it!
Let's use "Ondoku" to compare words that actually use two "e" sounds.
Examples of words that use the vowel "é"
| word | audio | meaning |
|---|---|---|
| bela | to protect, to defend | |
| pesta | party |
Examples of words that use the vowel "e"
| word | audio | meaning |
|---|---|---|
| semua | all | |
| kemarin | yesterday |
What are the key points of Indonesian diphthongs (ai, au, oi)? Check it out with audio
Indonesian has three diphthongs: "ai," "au," and "oi."
The trick to pronunciation is to not give up halfway through!
In Japanese, the sound "ai" can be ambiguous, with "ai" becoming "ai," but in Indonesian, the vowel is pronounced clearly to the end .
Let's compare the audio created with "Ondoku" .
Examples of words that use the diphthong "ai"
| word | audio | meaning |
|---|---|---|
| Ramai | busy | |
| Damai | peaceful |
Examples of words that use the diphthong "au"
| word | audio | meaning |

|---|---|---|
| toilet | toilet | |
| boikot | boycott |
