August 21, 2024

Which AI transcription service is the most accurate when dealing with a bad audio recording? We put six of the best to the test to find out.


Six of the top AI transcription services compared

Have you ever wondered if a different AI transcription service, plugin, or feature of your favorite post-production app is better than what you’re currently using?

Well, wonder no more!

I’ve compared these six top transcription tools to find the most accurate service:

Although accuracy is obviously an important factor in choosing a transcription service, other considerations include ease of use and extended functionality.

Having a less accurate transcription service, yet one that sits on your timeline or allows you to do text-based editing will probably be more useful than a more accurate third-party service to which you have to upload all your media.

The Test

I didn’t want to make the process too easy, so I’ve chosen an audio sample that has several major problems with it.

  • It was recorded on my iPhone
  • It was recorded on my iPhone in a noisy hotel bar
  • It was recorded on my iPhone with two different native speakers
  • One of whom tends to mumble.

Listen to the clip (it is harsh):

This sample is taken from an interview I did with veteran editor Steve Audette. You can hear the full clip on YouTube: The Difference A Film Editor Makes

And here’s what the transcription should say:

Speaker 1

What keeps you in the edit chair? Like, why do this for your whole—

Speaker 2

Yeah. I actually love it. I was cutting a scene today of, uh, the reporter, you know, shot of her looking at her phone, and then they shot to full-screen video of what she was supposedly looking at on the phone, and then left the footage with what was on the screen and left to go to the next scene.

And I was saying, wow, what a wasted opportunity here. You know, I can make this beautiful. This is just like a scene that’s just sitting here. We could actually, you know, make this into a story.

The Results – Observations and Conclusions

Using all of these transcription services is incredibly easy. Each one only takes a few seconds to load or upload the clip and then transcribe the 30 seconds of audio.

The transcription just needs to get two things right:

  • Separating who is talking
  • Correctly parsing what they are saying
