[AI transcription] 6 points of recording for high-precision transcription|Mr. Transcription

In recent years, with the development of AI technology, the number of transcription services using speech recognition engines is increasing. Cheaper with AI! Efficiently! You can now transcribe.

But I transcribed it with AI, but I can't transcribe it properly
There is a point for high-precision transcription with AI!

In order to perform highly accurate AI transcription, it is important to incorporate several techniques when recording.

In this article, we will introduce the best recording points when transcribing with AI.

6 points for optimal recording when transcribing with AI

  1. high quality microphone
  2. the mic is in the right place
  3. Create a quiet recording environment
  4. Clarify the speaker's utterance
  5. speak one by one
  6. do a recording test

1. Use a good quality microphone

To improve the accuracy of the speech recognition engine, first use a high-quality microphone.

You can also record audio with the built-in microphone of your PC or smartphone, but it cannot be said to be of high quality.

A high-quality microphone keeps your voice clear and minimizes noise.

This makes it easier for AI to recognize speech accurately.

2. the mic is in the right place

Microphone placement is also important.

If the microphone is too far from the speaker, the voice will be small and the recognition accuracy will be low when transcribed by AI.

Conversely, if the microphone is too close to the speaker, the speech will become saturated, which will adversely affect recognition accuracy when transcribed by AI.

Keep your distance and aim your mic accurately.

3. Create a quiet recording environment

A quiet recording environment reduces noise and improves the accuracy of speech recognition when transcribed by AI.

Even so, if you use a square, narrow meeting room , your voice will echo like a bathroom. If you record in that environment, the recorded audio will be full of echoes and howling and not very audible.

In addition, the sound of air conditioners and fans also becomes noise. Try to keep it away from the mic.

Also, installing sound absorbing materials in the room can further improve the recording environment.

4. Clarify the speaker's utterance

Speaking slowly and clearly makes it easier for AI to recognize your voice.

The speaker speaks slowly and clearly, like a newscaster, and speaks in standard language for better transcription.

5. speak one by one

When multiple speakers speak at the same time, it becomes difficult for the speech recognition engine to recognize them accurately.

If you are thinking of transcribing with AI, try to speak one by one.

6. do a recording test

If you hit anything and do it in production, you may fail.

The same is true for recording. Before you start recording, be sure to do a test recording.

By performing a test recording, you can check the volume and sound quality, and make adjustments if there are any problems.

This reduces the risk of errors in your production recording.

Examples of audio that are actually difficult to transcribe

This is an example for Japanese.

I hope that the atmosphere such as the noise level and the way the microphone is inserted can be a reference for the difficulty of AI transcription of voice.

*As an example, there is no relationship between the distributor and the content of the video, etc., and this service.

Audio files that AI transcription is not good at

  1. The voice is low, the microphone is far away and it is difficult to hear
  2. Loud noise and drowned out audio
  3. Audio is blurry due to room reflections
  4. Items containing music, such as song lyrics
  5. without sound
  6. tight dialect
  7. something that is difficult for people to hear

When AI couldn't transcribe well

Appropriate recording techniques are essential for highly accurate transcription by AI (speech recognition engine).

Please keep the points introduced this time in check and use AI technology to efficiently transcribe.

However, for audio files that do not transcribe well with AI transcription, it is more reliable to ask for human transcription.


But isn't it expensive to ask someone to transcribe it?
