Changes in translation by deep learning and 4 translation services!


In recent years, deep learning, which has been utilized in various situations, is also used for translation functions.

However, many people may not know what deep learning is and how it affects the translation function.

In this article, we will introduce changes in translation by deep learning and case studies of services.

How deep learning changed translation

The translation function uses deep learning to enable natural translation.

Originally, the translation function used “rule translation” to translate according to the syntax and grammatical rules designed by the developer, and “statistical translation” to display the translation results by collecting and utilizing dialogue data.

Since the above requires a huge amount of data, it was difficult to improve the accuracy significantly.

However, by using ” deep learning “, it is now possible to “judge and translate words that have two different meanings in a sentence”.

As a result, the accuracy has improved and the natural translation that the local people use has become possible.

Mechanism of translation by deep learning

The core of AI technology is the concept of ” deep learning “, and this deep learning is used for translation.

As a translation mechanism using deep learning, it can be explained as “continuously learning from a large amount of information and examples of answers in a way similar to how humans learn, and automatically creating rules.”

In addition, after considering grammar, we translate with emphasis on “what kind of space and what kind of information will be placed.”

In addition, there is still room for improvement because there is another point that “data can be sustained”, and it is expected that the accuracy will continue to increase in the future.

Advantages of using a deep learning translation service

The advantages of using the deep learning translation service are the following three points.

  1. high accuracy
  2. Increase work efficiency
  3. Easy mass translation

High accuracy

First of all, there is “high precision”.

By utilizing deep learning, it is possible to judge very ambiguous things. For this reason, similar meanings are identified, grammar is taken into consideration, and natural sentences are completed.

In addition, translation using deep learning will continue to learn, so the accuracy will continue to increase in the future.

Increase work efficiency

Next, there is the “work efficiency improvement”.

Because it is more accurate than traditional translation services, there is no need to further check and rework what has been translated.

Until now, it was not possible to distinguish words with similar meanings or words with multiple meanings, so even if you used a translation service, the translation would not always be correct.

However, now that deep learning is used for translation, ambiguous expressions are translated into correct and natural sentences.

Even if an incorrect translation is made, it is certain that there are fewer mistakes with the current translation that utilizes deep learning.

Easy mass translation

Finally, there is the ability to easily translate a large amount of data.

For example, when using the translation service “DeepL”, if you enter the “source language”, the “translation language” will be displayed instantly.

In the original text box, you can type directly, copy and paste text that you have finished writing with an editor, etc., and you can translate 1300 characters in just 5 seconds.

Therefore, anyone can easily translate a large amount of text.

4 Translation Services Using Deep Learning

Here are four recommended translation services that utilize deep learning.

  1. Deep L
  2. Amazon Translate
  3. Zinrai Translation Service
  4. AI automatic translation service

I will give an overview of each.

Deep L

First of all, it is “DeepL”.

DeepL is an online foreign language automatic translation tool that appeared in 2017 and is now free to use.

In addition, a paid version service “DeepL Pro” for BtoB has also been developed, and access to APIs for creating DeepL-based applications for developers is complete.

The free version of DeepL can be translated to and from Japanese in 11 languages, including English, French, German, Spanish, and Chinese, so there is no need to worry.

In addition to instantly translating, it is attractive that it translates surprisingly naturally. In particular, there are few services that translate proper nouns as they are, so you can see the high accuracy.

Next is “Amazon Translate”.

Amazon Translate is a translation service provided by Amazon and can be used free of charge, but you may be charged for customizing it, such as using it in conjunction with other apps.

Even if it is free, you can translate up to 2 million characters, so you can use it without any problems.

Features include “easily integrated with applications,” “customizable,” and “wide usage.”

By “wide usage” we mean that it is possible to translate a variety of content formats such as Word documents, Powerpoint presentations, Excel spreadsheets, etc.

Zinrai Translation Service

Next is “Zinrai Translation Service”.

Zinrai Translation Service is a translation service provided by Fujitsu. After a 14-day free trial period, a monthly fee of 55,000 yen to 660,000 yen will be charged depending on the plan.

Since it is a service made for companies, it is characterized by “file translation” that translates the layout as it is, such as contracts and business manuals.

It is also intended to be used for overseas business trips and customers whose native language is not Japanese.

In addition, since we have obtained “ASPIC certification” related to the safety and reliability of cloud services, there is no need to worry about leakage of company information.

AI automatic translation service

Finally, there is the AI ​​automatic translation service.

The AI ​​automatic translation service is a translation service provided by XEBEC and released for business use.

The most important feature of this service is that it can be used safely and securely because the server is managed in a data center with SSL and ISMS certification.

In addition, there are great strengths in terms of security, such as signing a non-disclosure agreement and having a function to automatically delete translation data saved on the server after two weeks in principle.

In addition, since it is possible to read and translate from Microsoft 365 and PDF, it is also attractive that the materials used in business can be translated easily and quickly.


What did you think.

In this article, we introduced the benefits of deep learning-based translation, its changes, examples of services, and how they work.

Deep learning translation has grown tremendously over the past few years and has become a natural part of our lives.
