The greatest feature is the ability to translate into natural Indonesian sentences.

The AI, which has learned the expressions of native Indonesian speakers, will translate the text into expressions that suit the content.

Enter the original text into the text box.

The Indonesian translation result is displayed immediately.

Once you copy the translation result, check if the content is correct by back-translating it.

If there are no errors in the translation result, it's OK.

Using Generative AI Services is Also Recommended

When you want to translate into Indonesian text close to native expressions, using generative AI services like ChatGPT, Claude, and Gemini is also recommended.

Please translate this text into native-sounding Indonesian text.

By giving instructions like this, it will translate into expressions used by native Indonesian speakers.

However, care is needed as attempting to translate long texts like video narration often reaches the limit of the free allowance.

2. Create Indonesian Audio with the AI Text-to-Speech App Ondoku

Next, read out the translated text using Ondoku.

Ondoku is a web app that can be used for free through a browser.

It's easy to use just by opening the page from here.

Select "Indonesia (Indonesia)" from the language options.

3. Utilize Indonesian AI Voice for Learning and YouTube Video Production

Now just utilize the created Indonesian audio for language learning or YouTube video production.

In language learning, it is recommended to use Ondoku's reading speed change function.

When you feel the generated Indonesian audio is too fast, you can proceed with listening or shadowing practice little by little by lowering the reading speed.

Ondoku can lower the playback speed to 0.3x, making it perfect for Indonesian learning and study.

When making YouTube videos, it is recommended to add captions (subtitles) as well as Indonesian narration.

While you can add captions using the text used for reading, manually editing captions is very time-consuming.

We recommend creating an SRT file that can automatically insert video subtitles using the latest AI.

By loading the created Indonesian audio into the AI transcription service Mojiokoshi-san, you can automatically create an Indonesian subtitle file.

Then just download the SRT file and load it into video editing software like Adobe Premiere or DaVinci Resolve.

What are the points to be careful about when translating Japanese and Indonesian?

From here, we will briefly explain the points you should be careful about when translating Japanese text into Indonesian or Indonesian text into Japanese.

Check for Omitted Subjects in Japanese Sentences

Latest AI translation apps and software can translate Indonesian with very high accuracy.

However, by paying just a little attention to the original text, you can proceed with translation even more smoothly.

The first thing to watch for is the subject of the sentence.

Japanese is a language that often omits subjects like "I," "me," or "we."

For example, in the sentence "Ashita, ikimasu" (Going tomorrow), the subject "I" is omitted.

When translating into Indonesian, adding a subject like "I" to the original sentence before translating can prevent mistranslations.

Be Careful with the Translation of Indonesian Pronouns

Also, Indonesian pronouns have singular and plural forms.

For example,

• Second person singular: anda, etc.
• Second person plural: kamu, anda sekalian, etc.

Exist.

Particularly, in business-related text translation, care is needed as it is easy to be translated into plural forms even when the counterpart is one person.

Making Sentences Simple is Also a Key Point

To increase translation accuracy, making the source sentences simple is also a key point.

Long and complex sentences make it difficult for translation tools to translate accurately.

Breaking one sentence into short parts and making sentences where the relationship between subject and predicate is clear will increase translation accuracy.

Translation via English is Also Recommended

Actually, when translating Japanese into Indonesian, translating via English can be effective in some situations.

Many loanwords from English are used in Indonesian.

For example,

• komputer (computer)
• internet (internet)
• restoran (restaurant)

Etc.

Therefore, translation between English and Indonesian can often be done relatively smoothly.

While latest AI translation apps are high-performance, the learning data for direct translation between Japanese and Indonesian is smaller compared to "Japanese and English" or "English and Indonesian."

Therefore, depending on the case, going through English can lead to a more natural translation.

Particularly in technical or business documents, it is also recommended to compare direct Japanese-to-Indonesian translation with a two-step Japanese→English→Indonesian translation.

In this way, when translating Japanese and Indonesian, being aware of the differences in expressions in each language and slightly modifying the source sentence can lead to higher accuracy in translation.

Why don't you also use free AI apps more conveniently by being aware of translation points?

Why Not Try Conveniently Translating Indonesian with Free AI Apps and Software?

In this way, by utilizing free apps and software, anyone can easily translate Indonesian.

Furthermore, by using the AI text-to-speech app Ondoku, you can freely create language learning materials and YouTube video narration audio.

With latest AI, both Indonesian translation and Indonesian speech synthesis are OK for free.

Why don't you also utilize Indonesian more conveniently with AI apps?
