What is transcription? Explaining the basics and key points of recording transcription and audio transcription

First, let me briefly explain the key points of what back-translation means.
The original meaning of back-translation: A word that predates recorded speech
Transcribing is the process of transcribing audio that has been recorded into written text .
But originally it had a different meaning.
The original meaning of transliteration is to rewrite shorthand notes into a human-readable form .
Shorthand is a technique for recording the contents of sessions of the National Diet, local assemblies, trials, conferences, etc., using special characters called shorthand codes.
Since the shorthand symbols were unreadable as they were, they had to be later "translated" back into normal text.
Later, as audio recording technology improved and shorthand became less popular , transcribing audio came to be called "transcription."
Since it is transcribed from recorded audio, it is sometimes called "recorded audio transcription" or "audio transcription."
What is the difference between "transcription," "transcription," and "transcription"?
Previously, "transcription" meant transcribing shorthand, but now it means
- Reverse translation
- Transcription
- Transcription
- Transcription
are used with the same meaning .
Nowadays, the process of turning recorded audio into text is often called "transcription."
However, the word "reverse translation" is still used in government agencies and other places.
One example is the "transcript" used in court.
What is a transcript? Characteristics of audio recordings used in court
A word similar to "reverse translation " is "reverse translation book ."
A transcript is a written document of a recording that is used as evidence in court .
Transcriptions used as evidence in court must be transcribed in a prescribed format.
What's particularly important is that the audio recording is transcribed exactly as it was recorded .
If any part of the recording has been cut out or edited, it will not be accepted as evidence in court.
If you are creating a transcript for court, it is recommended that you transcribe the recorded audio using a method known as "raw transcription."
What are the three formats used in back-translation (transcription, tape transcription, and transcription)?
There are three main methods for converting audio into text:
Raw transcription: A verbatim translation of the recorded audio
Raw transcription is the process of transcribing audio recorded with an IC recorder or smartphone app, without changing a single word .
For example, meaningless words (filler words) such as "ah," "um," and "hm" are not omitted and are transcribed as is.
Because raw transcription is less likely to include the subjective opinion of the person making the transcription, it is used in situations where accuracy is required, such as court transcripts .
In addition, because it can capture mood and emotion, it is also used for recording and transcribing in applications where recording even the smallest nuances is important, such as counseling.
If you want to transcribe recorded text, we recommend free AI transcription services and apps.
If you want to record and transcribe audio raw, we recommend using a free AI transcription service.
An AI transcription service (transcription app) is a service that uses voice recognition AI to transcribe recorded audio .
The recorded audio is processed automatically , so you can transcribe it without missing a single thing.
Using a web app like Mr. Transcription , which can transcribe audio in just 10 minutes, can help you transcribe audio much faster than hiring a professional.
It's free to use, so why not give Mr. Transcription a try first?
*However, if you are using it as an official document, such as a court transcript, be sure to have it checked by an expert.
Trimming: Remove unnecessary parts of audio and record the transcript
When converting audio into text, trimming is the process of removing meaningless parts such as "ah," "um," and "hmm" when transcribing a recording .
The transcript will include any mistakes made by the speaker, but
- Speech style: A mix of desu-masu and da/aru-style
- Speaking order: Inverted, mixed topics
- The endings are "-ne" and "-yo"
These parts are converted into text as is, so the atmosphere of the meeting or interview can be preserved when transcribing.
Because it strikes a good balance between readability and accuracy of content , it is often used when transcribing meeting minutes and recordings of interviews and panel discussions.
Edited text: Audio recording and transcription with emphasis on readability
Refining text involves translating (transcription) a text into an easy-to-read form while maintaining the accuracy of the content .
The text that was transcribed was further revised to remove any unnecessary unnecessary parts.
- Converting spoken endings into written words
- Inverted sentences and rearrangement of topics
- Corrected obvious errors in the content
In this way, we will revise the text into an easy-to-read format .
This format is often used when recording audio content is to be used for publications or materials.
[Free] AI services and apps are recommended for recording and transcribing to remove imperfections and improve sentence structure
We also recommend using an AI transcription service (transcription app) when you need to transcribe text and tidy it up.

From here, we will explain the process of transcribing recorded audio using the free AI transcription service (web app) "Mr. Transcription."
1. Prepare the audio recording to be transcribed
First, prepare a recorded audio file to transcribe .
When recording audio with an IC recorder or smartphone app, paying attention to two points will ensure you record with good sound quality and no mistakes.
Dedicated stand for recording equipment provided
When recording meetings or interviews, it is recommended to have a dedicated stand for the recording equipment rather than placing it on the same desk where people are sitting.
If you place recording equipment on a desk, the speakers will pick up sounds such as your hands touching the desk or vibrations from typing on the keyboard, degrading the sound quality .
When recording with your smartphone, turn it on in airplane mode.
If you're recording audio using a smartphone app rather than a dedicated recording device, be sure to set your phone to airplane mode .
If you do not turn on airplane mode, recording may be interrupted if a call comes in .
Also, turn off notifications for the app .
