How many characters are there per hour in the audio of interviews and minutes? Transcription is easy with the use of free AI!

Aug. 2, 2021

• Creating minutes of the meeting
• Interview article

There are often scenes that require transcription of voice, such as when working.

Transcription is very cumbersome and requires a lot of work time if it is done manually.

Do you know how many voice characters there are per hour?

Also, how long does it take to actually transcribe?

I actually calculated and verified how many hours it would take.

How many audio characters are there per hour in interviews and minutes?

It is said that the average number of characters per hour of voice is about 15,000 to 20,000 characters.

However, it's just an average story.

• If you are elderly and speak slowly, it will be as small as 13,000 characters.
• In the case of conversations between friends, it is easy to speak quickly, and it can be as many as 25,000 characters.

If most of the hour is silent, the number of characters may be extremely reduced.

How long does it take to transcribe an hour of voice?

The time it takes to transcribe the average number of characters

1 hour sound source: about 4 hours

It is said that.

Let's actually calculate.

• For a one-hour interview: 17500 characters on average
• Number of characters that can be entered in 1 minute: 70 characters (about 1st grade of word processor test)

17500 characters ÷ 70 characters = 250 minutes

Even with a simple calculation, it takes 250 minutes = about 4 hours to transcribe an 1-hour interview.

It may take 7 to 10 hours if you make a mistake in typing, make a mistake in listening, or if the sound quality is poor and you hear it again and again.

The working time can be as short as 3 hours for a lecture in good recording condition.
However, it may take 7 to 10 hours if the sound quality is poor or if there are many speakers.

The number of characters is about 16,000 to 20,000.
