By introducing Ondoku, we have established a system that will lead to improved customer and employee satisfaction! Adire Law Office’s practical case study introduction
  • Adire Law Office
  • Size: 1,100 or more people, 220 or more lawyers (as of October 31, 2023)
  • Industry: Law firm
  • Interview: Attorney Kazumasa Hata (belongs to the Tokyo Bar Association)
    : Mr. Yasuda, Human Resources Department


Used in explanatory videos at the time of contract and narration of staff training materials. The process of preparing to create a high-quality product and adding people's voices takes a huge amount of time and effort.


Eliminate voice input in the office and create narration using Ondoku.


This eliminates the hassle of preparing detailed scripts and re-entering voices, which saves a lot of time.
The created videos can be used in various places to contribute to operational efficiency.

Introducing the company/introducing department

Attorney Mr. Hata (hereinafter referred to as Hata) We are a general law firm that primarily handles problems faced by individuals, such as debt problems, gender problems, and requests for government benefits related to hepatitis B.

Traditional law firms are somewhat intimidating, and it takes a lot of courage to consult with them. In order to change this situation, we are continuing our efforts to become a "close-to-home law firm."

For example, one of our firm's strengths is that we place friendly advertisements and have a system in place that allows for easy consultation over the phone. I also try to provide explanations that do not use technical terms as much as possible, so that people can feel closer to lawyers.

Please tell us about the background behind the introduction of the text reading tool.

QinCurrently , we provide our clients with explanations from our office not only verbally and in writing, but also in videos. Previously, we used to provide information verbally or in writing, but as a result of our pursuit of ease of understanding, we feel it is important to provide videos with illustrations and movements.

To create high-quality videos, you must also put effort into narration. However, even if we recorded the staff's voices, it would take a huge amount of time as we would have to redo the process many times.

Also, from the perspective of the recording environment, no matter how careful you are, you cannot avoid situations where the sound of a phone call or footsteps can be heard from outside.

As a result, it took a lot of time and effort to create videos.

Human Resources Department Mr. Yasuda (hereinafter referred to as Yasuda) In the Human Resources Department, every time we held orientation for new employees, we spent half a day explaining the same content. That's why I thought that if I could show videos that people could understand without having to explain things to people, it would help improve work efficiency.

I thought that a text-to-speech tool that could easily generate narration would help me start creating videos, so I decided to install it.

May I ask how you came to introduce Ondoku?

Qin The low price and ease of use are the deciding factors.

In particular, regarding ease of use, we evaluated the interface that can be operated intuitively. The text box and download notation are easy to understand, so there is no confusion when using it.

Another important point is that commercial use is OK since we are creating materials for subscribers. I decided to use Ondoku because it was easy to use, and I thought it would solve the problem of taking a huge amount of time to add voices.

Have the issues been resolved (improved) compared to before the introduction of Ondoku?

Before Qin , it could take up to six hours to add voice to a 10-minute video document.

I think it took three hours just to write the script so that the staff who added the voices could read it without hesitation. This is because the recording had to be successful on the first try, so we needed a perfect script. In order to maintain the quality of each word, I checked it out loud many times.

Also, I had to be very strict, having to re-record if even the slightest bit of external sound came in, so my time was wasted quickly.

However, currently, narration work can be completed in about an hour and a half. The fact that we no longer needed a human voice meant we didn't need a detailed script, and there was less need for rework.

YasudaHuman Resources Division began creating videos with the introduction of Ondoku. Until now, the hurdles to creating videos were so high that it was difficult to get started.

New employee orientation is held for new graduates and mid-career employees, so it is not uncommon for new employee orientation to be held about 10 times a month. The current situation was that the human resources department had to give explanations every time.

In order to improve our business operations, we incorporated videos with narration created using Ondoku into our training courses. As a result, it was found that the same level of understanding was gained as with oral training, and the human resources staff was able to use their time for tasks other than orientation.

Have you received any feedback about Ondoku within your office?

Yasuda : With the creation of video materials, students are saying that they are now able to review the content of the orientation at any time.

Explanatory videos for new employees using Ondoku can be reviewed at any time using shared data. Thanks to this, we were able to create a system that allows students to easily re-learn parts that they cannot remember using text-based methods using videos.

Additionally, employees assigned to branches across the country are encouraged to learn more efficiently by sharing videos from the headquarters.

If you have any further improvement requests for Ondoku, please let us know.

Yasuda : I think it would be even easier to use if the intonation could be improved. Especially when writing long sentences, you must try to cut them short until they sound the way you want them to sound.

Hata: I thought that if there was something like an easy-to-understand specification sheet, it would be more convenient to use. Currently, I am working on creating a voice that sounds natural through trial and error.

If Ondoku could provide us with some tips on how to use it, we might be able to spend more time focusing on the intonation of technical terms.

How do you plan to use Ondoku in the future?

I hope that Ondoku can be used to strengthen programs related to Qin education.

For example, you choose the correct answer from a list of options and move forward like an RPG. If there is training that can be practiced like a game, you can have fun while learning.

However, I think narration will be an important element for that purpose, so I would like Ondoku to play an active role at that time.

The Yasuda Human Resources Division plans to post videos on social media that can be easily viewed by job seekers, including new graduates. I would like Ondoku to solve all the narration problems that come up every time.
