I've looked at a lot of tools, but when there are 15 of them, I still don't know how to choose the one that best suits my purpose...

For you, we will introduce transcription tools specialized for each of the usage scenarios of audio transcription.

I want to transcribe easily and smoothly.

I want to easily transcribe

If you want a tool that is easy to use and allows you to quickly transcribe without getting confused, we recommend "Mr. Transcription."

It's very easy to operate!

Just open the page and upload your file.

Of course, in terms of performance, it is possible to use a high-performance AI speech recognition engine, so the accuracy of transcription is outstanding .

If you're not sure which one to use, try using Mr. Transcription first.

I want to transcribe many types of files.

Transcribe many types of files

If you want to transcribe many types of files , we recommend Mr. Transcription .

The feature of Mr. Transcription is that it can transcribe not only audio files but also images, videos, and PDF files .

Specifically, it supports the following file formats.

  • Audio: .mp3 .wav .wma .m4a .aifc .flac .aac .aiff .aifc
  • Video: .mp4 .mov .avi .flv .mkv .webm .wmv .3gp
  • Images: .jpg .jpeg .png .webp
  • Text: .pdf

Of course, you can also just upload audio files recorded on your iPhone or Android smartphone.

You can transcribe it without any hesitation.

Another point is that there is no need to convert video files to audio files .

If you want to easily transcribe using AI without having to worry about file formats, we recommend Mr. Transcription.

I want to take the minutes of the meeting.

Meeting transcription

If you are given audio data from a meeting and want to transcribe it, we recommend "Mr. Transcription" !

As I mentioned above, ``Transcription'' supports not only audio data but also video data, so when you want to transcribe a video of a lecture or conference, you don't have to worry about converting the video file to an audio file. It doesn't cost anything.

Another good option is ``Voice Rep Pro.''
Additionally, if you are participating in the meeting yourself, the ``User Local Audio Minute System'' is also convenient.

If you don't have the time to transcribe by hand, it's a good idea to use an outsourcing service such as Koerabo.

I want to transcribe the interview

If you want to use your smartphone as a voice recorder while simultaneously recording and transcribing in real time, ``Texter'' and ``Notta'' are useful.

If you would like to prepare a separate IC recorder, ``AutoMemo'', which comes as a set with a transcription service, is perfect (note that it comes with the hardware as a set).


As with minutes, if you are only given audio data, try using ``Mr. Transcription.''

I want to use it like a voice memo

Among apps and services other than standard smartphone voice memos, we recommend ``Texter'' and ``Edivoice'' if you want to easily take voice memos on the go.

Texter is also compatible with Apple Watch, so you can record voice memos even when your smartphone is in your pocket or bag.

If you want to sit down in front of your computer and input a certain amount of text by voice, you might find it convenient to use ``Voice Rep Pro,'' which has a built-in editor that also includes proofreading tools.

If you just want to record something, a smartphone standard voice memo or recorder app is actually sufficient.
If you want to transcribe it using an external service, you can upload the file to Mr. Transcription .

I want to transcribe English audio

"Mr. Transcription" supports 99 different languages, including English!

Otter is a tool that specializes in English audio transcription .
Other tools that claim to be compatible with English, such as Notta, are also a good option.
Notta supports many languages ​​and has a built-in translation function, so it is also suitable for those who want to use it as a language learning tool.

I want to use it in an offline environment

offline environment

Almost all recent transcription services, including the tools introduced this time, use AI to convert speech to text in the cloud, so they cannot be used in places without an internet connection.

*For manual transcription services, audio data is mainly exchanged via the internet.

If you want to perform transcription work in an environment where you cannot connect to the Internet,

  • Offline environment: Recording, text correction, etc.
  • Online environment: Automatic transcription only when connected to the internet

It is necessary to use them properly.

We recommend recording with an IC recorder or smartphone in an offline environment, and when you can connect to the internet, use an AI transcription service like Mr. Transcription .

Alternatively, you could acquire existing stock of standalone software such as Dragon Speech or AmiVoice SP2, which are currently discontinued.

Types of transcription tools

We have introduced various types of transcription tools, including those that can be used for free, and recommendations for each scene.
From here, let's take a closer look at the features of the transcription tool .

What types of transcription tools are there?

There are several classifications, including AI and manual methods, web and PC/smartphone apps, but what are the differences?

AI transcription and manual transcription

One of the classifications of transcription is whether it is ``transcribed by AI'' or ``transcribed by hand using a keyboard.''

Image of AI

Most of the tools and services introduced this time are AI transcription services.
Among the services I introduced, ``Koerabo'' is a service where writers transcribe text.

It feels like the spread of AI is progressing all at once, with Stable Diffusion (image generation AI) in 2022 and ChatGPT in 2023.
Of course, AI is the biggest reason why high-quality transcription services are becoming more accessible.

Even before that, the ability to transcribe audio files on a computer existed.
However, until AI became widespread in recent years, it could be said that it lacked practicality .
Some of you may have tried voice input on an old computer and found it unusable.

type with keyboard

So, previously, if you wanted to transcribe something, you had no choice but to keep typing on the keyboard while listening to the audio file.
Do you take the time to transcribe it yourself, or pay a professional to do it for you?
In both cases, the end result was that a person was typing on a keyboard.

But not now!
High-quality transcription, including ``Mr. Transcription'' , is free - available at a very reasonable price!

Transcription is one of the areas benefiting the most from AI .
If you only know old transcription software, try it and you will be amazed at its performance!

Please try out transcription for free.

Environment for transcription (web/PC/smartphone)

Next, the type of environment in which transcription is performed is another classification.
The difference is whether you do it on the web, or with a PC or smartphone app .

In the past, recognizing and transcribing speech was often done by installing an app (software) on a PC.
However, things have changed now that AI transcription has become widespread.

AI transcription is mainly used from the web

Now that AI transcription services have become widespread, the most commonly used services are web, that is, services used with browsers such as Chrome, Safari, and Edge.

Services used on the web are the mainstream

For example, with ``Mr. Transcription'', all you have to do is open the top page and upload files such as audio and video!

In this way, many AI transcription services are used by opening the service's website in a browser .

The biggest reason why many AI transcriptions are done in a web environment is that a high-performance computer is required to use advanced AI .
Some enthusiasts run various types of AI on high-performance PCs at home, but not all AIs can be run on PCs that can be installed at home.
Also, even if AI were to work on your home PC, you would not be able to import the audio data to your home PC if you want to transcribe it for work.

On the other hand, if you are uploading an audio file to a powerful computer over the Internet, the performance of your home computer is irrelevant.

Can be used in any web environment

Also, there is another benefit to using transcription services from the web!

This means that you can use it in any environment, whether it's a PC or a smartphone .

Can be used on PC or smartphone

For example , if you record using your smartphone while on the go, you can upload it to an AI transcription service from your browser.
When you return to the office, check the transcription results on your computer .
You can easily use it like that.

Of course, it doesn't take much time to install.

If you are currently using a transcription service , we recommend using a web service such as ``Mr. Transcription'' !

Upload or real time?

One last point: whether you upload an audio file and transcribe it, or whether what you're saying is transcribed in real time depends on the service.

Transcription time

The difference between an upload service and a real-time service is the time it takes to complete the transcription .
Of course, with real-time transcription services, transcription is completed the moment the meeting ends.
On the other hand, with transcription services that require uploading, no matter how fast the recording is finished, it takes time to upload and wait for the process to finish.

You need to consider how much time difference there will be in actual use.
For example, in the case of minutes or interviews, in order to summarize them in their final form, it is necessary to check the transcription for errors, kanji conversion, and proper noun errors .
This effort is also necessary for real-time transcription.

Additionally, upload-to-transcribe services such as ``Transcription'' have the advantage of being compatible with many types of audio and video files, since you only need to upload the file later .

A real-time transcription service is required for purposes such as "simultaneously distributing transcribed content," but for other purposes, a service that uploads files and uses them may be more flexible .

Recommended types of transcription tools

So far, we have looked at the types of transcription tools from various aspects.

So, with that in mind, what tools do you recommend?

In conclusion

  • AI transcription
  • Use from the web
  • Upload and use

This is recommended if you are going to transcribe from now on.

If you are looking for a transcription service, if you choose these three points, you are sure to get good results.

``Mr. Transcription'' is one such transcription tool, so why not try it for free first?

Things to consider when choosing a transcription tool

So, what should you pay attention to when choosing a transcription tool?

Check if you can try it for free

The first thing to keep in mind when choosing a transcription tool.
That's why you can try it for free before paying to use it .

Can I try it for free before paying to use it?

For example, you can try ``Mr. Transcription'' for free without registering (click here for more information about the free trial) .

Why is a free trial feature like this important?
This is because you can check how high the quality of the transcription can actually be .

It would be a shame if you couldn't transcribe it until you paid, and the quality was poor when it was actually transcribed.
Although the performance of AI transcription is steadily improving, there are some issues that make it unsuitable, depending on the quality of the audio, such as audio from specialized fields or noise .
Therefore , by transcribing only part of the audio in a test, you can see whether each transcription service can smoothly transcribe the audio you want to transcribe .

You can try “Mr. Transcription” for free!


As I mentioned above, you can try “Mr. Transcription” for free!
You can try it for free for up to 1 minute without registering, but by registering as a free member, you can use AI to transcribe audio files of up to 1 minute each day for up to 10 minutes.

Why not try out the high quality of the latest AI transcription for free?

Check the time when you can transcribe

The amount of time you can transcribe varies depending on the tool.
Also, even with the same service, the amount of time you can transcribe may vary depending on the plan.

For example, ``Mr. Transcription'' has multiple plans, ranging from a free plan that allows you to transcribe for up to 10 minutes per day to a plan that allows you to transcribe for 20 hours per month (Reference: Mr. Transcription's Features | Audio/ Transcription of videos and images) .
When subscribing to a transcription tool, choose one that matches the length of the audio you are transcribing and the frequency of transcription.

Check security

Security is a concern when using transcription tools.
Especially for business purposes such as transcription of meeting minutes, it is only natural that you will not be allowed to use the service for work unless it is recognized as having no security issues.

Therefore, when choosing a transcription tool, it is important to check whether each service has appropriate security measures .

Check security

For example, in the case of Mr. Transcription, we have taken thorough security measures, including not leaving any logs in the AI ​​engine (Reference 1: "Specifications and Security" Reference 2: "Terms of Service" ).
This is the most important point when using transcription for work , so be sure to check the security measures of the transcription service in advance!

How many languages ​​does it support?


The most common people reading this article are probably looking for a Japanese transcription tool.
However, an important point is how many languages ​​it supports .

Japanese is of course available, but many services available in Japan also support English.
However, other languages ​​may not be supported unless you select a service.

Why multilingual support is important.
This is because transcription can easily be translated into Japanese .

Translation is also an area where the quality has suddenly improved thanks to the power of AI, including DeepL, which is now very popular.
By combining AI transcription and AI translation, you can easily read business documents from overseas.

For example, "Mr. Transcription" supports 99 languages!
When choosing a transcription tool, don't forget to check whether it supports multiple languages.


This time, we have explained recommended audio transcription tools and how to choose and use them .

Finally, I would like to summarize the software and services introduced in the article once again.

  • Mr. Transcription : Versatile. Just upload the file and AI will automatically transcribe it.
  • Texter : Easy voice memo/transcription on iPhone or Apple Watch
  • Edivoice : High-performance voice input keyboard for Android
  • Notta : A smartphone transcription app that is strong in translation. A dedicated microphone is also recommended.
  • AutoMemo : IC recorder + transcription tool set

  • YOMEL : Transcription tool specialized for meetings

Each tool has its own strengths and weaknesses, so choose the best software or service for what you want to do, and sometimes try combining them through trial and error!

Many of them are free to try, so it's important to try them out and get a feel for how easy they are to use.
