How to create foreign language audio (Vietnamese, Chinese, Filipino, Indonesian, Burmese, etc.) Easily provide instructions for training and on-site using AI voice!

The acceptance of technical interns in Japanese companies is increasing.

However, providing that training can be quite a struggle.

The language barrier is particularly large, and there are many situations where it is difficult to provide specific guidance to interns who are not proficient in Japanese.

To solve this problem, companies are also required to show ingenuity and effort.

As one such method, the utilization of AI voice is effective.

How to Create Foreign Language Audio with Ondoku

The method for creating foreign language audio using AI voice is very simple.

  1. Translate Japanese text into a foreign language (e.g., Vietnamese) using a translation service such as Google Translate.
  2. Input the translated Vietnamese text into the Ondoku text box.
  3. Select a Vietnamese voice.
  4. Click the read aloud button to output it as Vietnamese audio.

With just these steps, it becomes possible to convert Japanese text into Vietnamese audio.

  • There is no need to ask someone fluent in a foreign language,
  • there is no loss of time for meetings or re-recordings,
  • and no recording environment such as a microphone is required.

Of course, you can choose not only Vietnamese but also 49 languages and dialects including Chinese, Filipino, Indonesian, and Burmese.

Ondoku supports reading aloud in languages from countries all over the world. There are 49 languages and dialects. In terms of the number of speakers, there are over 300 in total.

Note: Ondoku itself does not have a translation function

Ondoku itself does not have a translation function.

Therefore, translation must be performed separately.

For this reason, when creating audio with Ondoku, you first perform the translation and then generate the audio.

For translation, please use external services such as:

Warning: Inputting Japanese and reading it aloud in a foreign language only creates audio that "sounds like" it

Even if you directly input Japanese into a foreign language voice setting, the AI voice will simply read the Japanese phrase as if it were the foreign language; it will not result in audio that reflects the translated meaning.

For example,

Japanese: こんにちは。私の名前はケンです。 (Hello. My name is Ken.)

Suppose you want English audio with this meaning, but you try to output the Japanese text directly using an English voice.

The resulting narration will sound like this:

Kenichi idiographic.idiographic.

Actual audio:

In this case, even though the required audio is

Hello. My name is Ken.

it is clear that it is just being read in an English-like way, and the meaning is incomprehensible.

This means that the AI voice does not understand the specific meaning of "converting Japanese into foreign language audio."

To obtain accurate foreign language audio, a step to translate the Japanese into the target language is first required.

Japanese: こんにちは。私の名前はケンです。

If you want English audio with this meaning, you must translate it first and then input the translated text

Hello. My name is Ken.

into Ondoku to be read aloud.

Benefits of Utilizing AI Voice in Technical Intern Training

Utilizing AI voice in the training of technical interns offers numerous benefits.

1. Language barriers are reduced

When training or instructions for foreign interns are necessary, using AI voice can significantly bridge the language barrier.

By converting training content into the intern's native language using AI voice, it becomes easier for them to understand specific instructions.

Some people may not be good at reading text.

In such cases, being able to hear their native language as audio is a significant advantage.

Even if you conduct training, it is meaningless if the content is not understood or if instructions are not clear.

2. AI voice can be used regardless of time or place

AI voice can be used anytime and anywhere. This makes it possible for interns to proceed with self-study even outside of training hours.

Furthermore, the ability to listen to the training content as many times as desired is a major benefit. This allows them to later confirm parts where their understanding couldn't keep up, enhancing the learning effect.

Utilizing AI voice significantly reduces the burden on the company side

Using AI voice can significantly reduce the burden on the company. Since content can be converted to audio in advance, it eliminates the need to explain the same content over and over again.

These factors demonstrate the effectiveness of utilizing AI voice for the training of technical interns.

Utilize AI Voice to Assist in Foreigner Training and On-site Communication

As of 2019, Vietnam accounted for the highest percentage of technical interns by nationality, followed by China, the Philippines, Indonesia, and Thailand.

By utilizing AI voice, you can smoothly conduct training for foreign staff, such as Vietnamese nationals, and facilitate communication with those on-site.

Please consider utilizing Ondoku as a means to convey information across language barriers.
