Free available: 10 recommended voice transcription tools [AI/Web/App]|Mr. Transcription

Want to speedily transcribe meeting minutes and interviews?

Don't you have such a problem?

Not so long ago, it was commonplace to transcribe all these meetings and conversations manually.

With the spread of personal computers, playback players and editors dedicated to transcription have appeared, but the effect is only partial reduction of labor. In the end, there was no choice but to do the transcription itself, one by one, manually.


There were several agencies, but there weren't many that small and medium-sized companies and individuals could easily ask.

But times have changed.

Transcription tools that anyone can easily use are now being created one after another, and they are steadily stealing our jobs (in a good way).

This time, among such convenient voice transcription software services , we will introduce 10 particularly recommended tools.

We also explain in detail how to choose the best tool for your purpose and usage scene, so if you read this article, your work will be overwhelmingly easier compared to 100% manual work like before. Please take a look to the end.
