I'm a beginner but I want to know how to transcribe interviews!

An important aspect of interview interviews is to transcribe what you hear.

When publishing an interview as an article on the web or in print, or using it as a resource, transcribing it is the first step.

However, transcribing interview content manually by typing on a keyboard is extremely time-consuming and laborious.

In this article, we will thoroughly explain how to transcribe the content of your interviews smoothly and accurately .

We recommend an AI transcription service, whose performance and functionality have improved rapidly in recent years.

In particular, we recommend choosing a service that has a "speaker separation function."

There are a number of convenient features that make it easy for even beginners to transcribe interview content into text , so why not try using them using this article as a reference?

What is interview/coverage transcription?

Transcription, the process of turning audio content into written form, is an essential task after conducting an interview.

What does it take to transcribe an interview?

How can I transcribe an interview?

How can I transcribe an interview?

In order to use the information obtained during an interview for web or paper articles, research or paper materials, etc., it is necessary to transcribe it (transcribe the tape) and turn it into text.

In an interview, the person conducting the interview (listener, interviewer) asks questions to the person being interviewed (speaker, interviewee) and the interview proceeds as the two talk.

*There may be cases where more than three people are interviewed at the same time.

Transcribing an interview differs from other types of transcription, such as lectures or dictation, in that it requires transcribing what multiple people say separately (speaker separation) , so beginners can find the process difficult to master.

Types of Interview Transcriptions

Types of Interview Transcriptions

There are three stages to transcribing an interview depending on how much trimming you want to do to the audio.

  • Raw transcription
  • Removing fraying
  • Text


Raw transcription

Transcription is the stage where what was said is transcribed exactly as it is (transcribed onto tape) .

We transcribe exactly what you say , including meaningless words like "ah," "uh," and "hmm," as well as any slip-ups.

Interviewer: So first of all, I'd like you to tell me about a product that you've recently developed.

Speaker: I guess it would be an innovative smart home device. Well, it was born out of a request from our customers to improve the convenience of their daily lives.

Interviewer: Wow, so what are your differences and advantages over your competitors?

Speaker: When you did your competitive analysis, you looked at a device that already existed on the market, and you looked at that in detail.

This will transcribe exactly what was said during the interview.

Removing fraying

De-cluttering involves removing unnecessary parts, such as meaningless words like "ah," "eh," and "hm," or mistakes in speech, to make text easier to read.

This is a relatively common stage in transcribing interviews as it allows for subtle nuances to be preserved.

Interviewer: First of all, I'd like to know about the products you've developed recently.

Speaker: I guess it would be an innovative smart home device. It was born out of a request from our customers to improve the convenience of their daily lives.

Interviewer: What are your differences and advantages over your competitors?

Speaker: During your competitive analysis, there were devices that already existed in the market that you looked at in detail.

In this way, by removing unnecessary parts, the transcribed content is easier to read than the raw transcription.


Refining the text is the process of polishing the content that has been smoothed out into its final form .

  • Convert spoken content into written form
  • Customize the writing style to suit the purpose, such as a business article or a frank article.

We perform tasks such as:

This is often done in the final stages of preparing the interview content for publication as an article.

Interviewer: First, can you tell us about the products you have recently developed?

Speaker: It's an innovative smart home device. It was created based on customer feedback to improve the convenience of everyday life.

Interviewer: Can you tell us what makes you different and what your advantages are compared to your competitors?

Speaker: The competitive analysis involved taking an in-depth look at the devices already available on the market.

In this example, the content has been adapted from the frank, conversational tone of the initial interview to a style more appropriate for a business interview article.
