Next, we’ll briefly explain some key points for studying Vietnamese!
Vietnamese is becoming an increasingly important language
In recent years, ties between Japan and Vietnam have continued to grow stronger.
Economically, many Japanese companies have expanded into Vietnam and are actively developing their businesses there.
In addition, many Vietnamese people visit Japan as technical interns or international students, and cultural exchange between the two countries is flourishing.
Against this backdrop, the number of Japanese people studying Vietnamese is steadily increasing, and interest in Vietnamese is also growing in the language-learning market.

However, Vietnamese is a very difficult language to learn.
Many learners have likely found that traditional textbooks and reference books alone have their limits when it comes to studying Vietnamese.
Pronunciation is especially challenging because Vietnamese has a tone system that Japanese speakers are unfamiliar with, making it very difficult to master correct pronunciation.
That’s why AI-powered read-aloud services and text-to-speech tools are attracting attention.
Advances in AI have greatly improved the efficiency and quality of Vietnamese language learning.
What are the characteristics of Vietnamese? Tips for studying smoothly
Understanding the basic characteristics of Vietnamese is essential to studying it effectively.
Here’s an overview of the characteristics of Vietnamese.
Vietnamese is a tonal language
Vietnamese is known as a tonal language and has six distinct tones.
It has more tones than Chinese, a language often considered difficult to pronounce, which has four. Mastering the tones is the biggest challenge in learning Vietnamese.
Tone is a system in which the meaning changes depending on pitch and intonation, even when the sounds themselves are the same.
Unless you can pronounce and distinguish subtle differences in tone accurately, communication in Vietnamese is not possible.
Understanding the Vietnamese writing system is also important
Vietnamese also has a distinctive writing system.
It is currently written using Quốc Ngữ, a Latin-based writing system, which was devised by missionaries in the 17th century and became widely adopted as the official script during the French colonial period.
This system uses various marks (diacritics) to indicate tones.
For learners, understanding what these marks mean and reflecting them correctly in pronunciation is an important challenge.
We recommend reading aloud when learning Vietnamese!
As Vietnamese is such a challenging language, reading aloud is a great way to study it.
Here’s a brief explanation of why.
How reading aloud helps you learn Vietnamese
The importance of reading aloud in language learning is widely recognized, and it is just as effective for learning Vietnamese!
Reading aloud regularly helps you develop a natural feel for tones and learn to pronounce words accurately.
Reading aloud also greatly helps with memorization, making it easier to learn vocabulary and grammatical patterns.
Auditory training through reading aloud is especially essential for tonal languages like Vietnamese.
By listening to yourself as you speak, you can develop accurate tone patterns and gradually learn to pronounce words more like a native speaker.
Reading aloud also trains the muscles in your mouth and the movement of your tongue, helping you accurately pronounce sounds unique to Vietnamese.
Benefits of using the latest AI text-to-speech technology to learn Vietnamese
Advances in AI have dramatically improved the quality of Vietnamese text-to-speech services.
The latest AI speech synthesis services can generate natural-sounding audio with native-speaker pronunciation.
They can be used as powerful tools for language learning.
The greatest benefit of using text-to-speech technology for studying is that you can check accurate pronunciation whenever you want.
In the past, opportunities to have a native speaker check your pronunciation were limited. But with a text-to-speech tool, you can listen to correct pronunciation whenever you like, 24 hours a day, 365 days a year.
You can also listen to the same sentence as many times as you like, making it possible to analyze subtle differences in sounds and changes in tone in detail.
With AI, you can adjust the reading speed however you like
A key feature of AI text-to-speech services is that you can adjust the reading speed.
Beginners can play audio at a slower-than-normal speed to hear each sound clearly.
Conversely, advanced learners can play it faster than normal to get used to the pace of natural conversation.
For example, “Ondoku” lets you slow the speed down to 0.3×, so you can take your time learning Vietnamese pronunciation.
By creating Vietnamese audio with “Ondoku”, you can also practice shadowing, which is highly effective for learning Vietnamese.
