AI Transcription: 6 Tips for High-Accuracy Recordings

In recent years, with the advancement of AI technology, there has been an increase in transcription services utilizing speech recognition engines. By leveraging AI, you can now transcribe audio cheaply and efficiently!

But I tried AI transcription, and it didn't transcribe properly.

There are key points to getting highly accurate AI transcriptions!

To achieve highly accurate AI transcription, it's crucial to incorporate several techniques during recording.

This article will introduce the optimal recording tips for AI transcription.

6 Optimal Recording Tips for AI Transcription

1. High-quality microphone
2. Proper microphone placement
3. Create a quiet recording environment
4. Ensure clear speaker articulation
5. Speak one person at a time
6. Conduct a recording test

1. Use a High-Quality Microphone

To improve the accuracy of speech recognition engines, start by using a high-quality microphone.

While you can record audio with built-in PC or smartphone microphones, they are not considered high-quality.

High-quality microphones maintain audio clarity and minimize noise.

This makes it easier for AI to accurately recognize speech.

2. Proper Microphone Placement

Microphone placement is also crucial.

If the microphone is too far from the speaker, the audio will be too quiet, leading to low recognition accuracy when transcribed by AI.

Conversely, if the microphone is too close to the speaker, the audio may become saturated, negatively impacting AI transcription accuracy.

Maintain an appropriate distance and adjust the microphone's direction precisely.

3. Create a Quiet Recording Environment

Creating a quiet recording environment reduces noise and improves speech recognition accuracy when using AI transcription.

However, using a square, narrow meeting room can cause voices to reverberate like in a bathroom. If you record in such an environment, the recorded audio will be full of echoes and feedback, making it very difficult to understand.

Also, sounds from air conditioners or fans can create noise. Keep them away from the microphone.

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

4. Ensure Clear Speaker Articulation

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

Speakers should articulate slowly and clearly, like a news anchor, and speak in standard language to achieve better transcription results.

5. Speak One Person at a Time

When multiple speakers talk simultaneously, it becomes difficult for speech recognition engines to accurately recognize the audio.

If you're planning to use AI for transcription, try to have one person speak at a time.

6. Conduct a Recording Test

Going into anything without preparation can lead to failure.

The same applies to recording. Always conduct a test recording before starting the actual recording.

A test recording allows you to check the volume and sound quality and make adjustments if there are any issues.

This reduces the risk of errors occurring during the main recording.

Examples of Audio Difficult for Transcription

These are examples in Japanese.

I hope these examples of noise levels and microphone input provide a good reference for what makes audio difficult for AI transcription.

※Please note that the streamers, video content, and our service are not related to these examples.

Audio Files That AI Transcription Struggles With

1. Audio that is too quiet, or where the microphone is too far away, making it hard to hear.
2. Audio where intense noise drowns out the speech.
3. Audio where indoor reverberation blurs the sound.
4. Audio containing music, such as song lyrics.
5. Audio with no speech.
6. Audio with strong dialects.
7. Audio that is difficult for a human to hear.

If you report an error for an audio file that AI transcription struggles with, it will be disapproved, and no time credit refunds will be issued.

In particular, many error reports are due to issues with the content of the file itself.

No Voice Recorded in the File (Continuous Noise or Silence)

If you upload an audio file without checking its content, you might find that the recording failed, resulting in "silent recording due to failure" or "microphone disconnected mid-recording, with only noise and no audio in parts."

The image above shows the result of transcribing a file that only contained noise.

Mojiokoshi-san uses AI for transcription. AI attempts to transcribe even noisy sections as much as possible.

If you get unintelligible transcription results like "ahhhhhhh" or "mmmmmm," please check the content of your file.

If you transcribe files like the one described above and consume your time credits, we cannot refund those credits.

What to Do When AI Transcription Doesn't Work Well

To achieve highly accurate transcription with AI (speech recognition engines), proper recording techniques are essential.

By following the tips introduced in this article, you can leverage AI technology for efficient transcription.

However, for audio files that AI transcription struggles with, it's still more reliable to request human transcription.

But isn't it expensive to ask a human to transcribe?

 AI transcription has its strengths and weaknesses.

For audio files that AI transcription excels at, use "AI Transcription."

For audio files it struggles with:

Try transcribing with AI
→ If it doesn't work, then use "Human Transcription"
This is recommended.

Since AI transcription is cost-effective, even for audio files that seem difficult for AI, you might get lucky and achieve good transcription results if you try it with a "nothing to lose, everything to gain" mindset.
