    What Is Audio Transcription? The Basics of Converting Audio to Text

    音声の文字起こしとは?

    Audio transcription means converting audio recorded with a smartphone voice memo app or an IC recorder into text (written characters).

    Transcription is also called “tape transcription” or “written transcription.”

    As it is, an audio file does not let you check its contents right away.

    Once the audio is in text form, you can find the information you need without playing the audio back.

    You can also make the contents of the audio more useful, for example by creating video subtitles or turning it into a web or magazine interview article.

    For Voice Memo Audio, an AI Transcription Service Is Recommended!

    The Steps to Transcribe Audio with the Latest AI [Voice Memos Supported]

    Tell me the actual steps for transcribing!
    cat

    We explain the steps for transcribing an audio file recorded with a voice memo app clearly, using images!

    1. Record the Audio File

    音声ファイルを録音する

    Use a smartphone voice memo app or an IC recorder to record the audio.

    Paying attention to a few points will help you record with good sound quality.

    Avoid Background Noise

    When recording with a smartphone voice memo app,

    • Place it on a desk or stand rather than holding it in your hand
    • Place it on a desk that nobody is using, so the sound of typing on a keyboard does not get in

    If you keep these two points in mind, background noise is less likely to get in.

    When recording outdoors, also consider attaching an external microphone and a windscreen to your smartphone or IC recorder.

    Make Sure Everyone's Voice Comes In at the Same Volume

    When recording several people's voices with a voice memo app, such as in a meeting or an interview, we recommend placing the recording device at the same distance from everyone.

    * If professional equipment is available, it is best to have the people being recorded wear lavalier microphones.

    2. Upload the Audio File

    Upload the recorded audio file to an AI transcription service.

    Here we explain using “Mr. Transcription.”

    Open the “Mr. Transcription” top page from this link.

    Audio Transcription Tips and Techniques Explained in Detail

    dog
    I want to know more about audio transcription!
    • For people who are about to transcribe audio
    • For people who want to make audio transcription work more efficient

    we explain the points and tips for transcription in detail!

    Knowing about transcription lets you convert audio recorded with a voice memo app into text even more conveniently.

    Types of Transcription: Verbatim, Clean Verbatim, and Edited

    文字起こしの種類

    Depending on how much the written-out content of the audio is polished, transcription comes in “verbatim (suokoshi),” “clean verbatim (kebatori),” and “edited (seibun),” 3 types in all.

    • Verbatim (suokoshi): transcribes even meaningless parts such as “um” and “uh” as they are
    • Clean verbatim (kebatori): transcribes with only parts such as “um” and “uh” removed
    • Edited (seibun): polishes the content of the text to make it easy to read

    Each has these characteristics.

    If you transcribe by yourself, the easiest is verbatim.

    Even so, transcribing 1 hour of audio takes 3 to 4 hours.

    You have to keep playing and stopping the audio while typing it on a keyboard, so until now, transcription has been very hard work.

    But with an AI transcription service, you can transcribe 1 hour of audio automatically in just about 1 minute.

    Audio Transcription Methods [AI Is Recommended!]

    音声文字起こしの方法【AIがおすすめ!】

    There are 2 ways to transcribe audio recorded with a smartphone voice memo app or an IC recorder.

    • Transcribe by typing on a keyboard
    • Transcribe with an AI transcription service (tool or app)

    These are the two.

    Until now, the only way to turn audio into text was to play a file recorded with a voice memo app and type it out on a keyboard.

    However, typing it yourself takes a very long time, and outsourcing it to a professional company or a writer cost a very high fee of tens of thousands of yen or more.

    Solve Your Transcription Troubles with AI!

    That is where AI transcription services came in.

    An AI transcription service is a tool or app in which speech recognition AI reads an audio file and transcribes it automatically.

    With an AI transcription service, transcription is complete in just about 1 minute.

    Typing on a keyboard takes 3 to 4 hours or more for 1 hour of audio, so transcription has become much faster and easier.

    Of course, the accuracy is outstanding too!

    It can accurately transcribe even difficult audio files with many technical terms.

    For audio transcription from now on, AI transcription services are recommended!

    Benefits of AI Transcription Services

    Once you start the transcription, the text is finished in about 1 minute.

    Because a high-accuracy AI does the work, there are none of the typing mistakes or wrong conversions that tend to happen when you transcribe while listening to a voice memo file yourself.

    2. Free to Use. Much Cheaper Than Professional Companies.

    AI transcription services can be used for free!

    Paid plans of AI transcription services are also much cheaper than professional companies.

    It is high-performance and costs next to nothing.

    3. Just Record. No Notes Needed!

    録音だけでOK。メモ不要!

    With an AI transcription service, you do not need to take notes at meetings or interviews.

    Just record with a voice memo app and everything can be turned into text easily, so you can concentrate on the content without taking notes.

    And with an AI transcription service, it is also easy to create meeting minutes from the transcribed text!

    Cautions About AI Transcription Services

    There are also points to watch out for when using an AI transcription service to convert voice memo audio to text.

    1. Features Differ by Service (Software or App)

    サービス(ソフト・アプリ)によって機能が異なる

    As introduced in this article, there are many kinds of AI transcription services, but their features differ, so be careful.

    • How long a recording can be transcribed
    • What kinds of situations they are good at, such as meetings or interviews
    • Whether they support foreign languages
    • Whether they can transcribe video, images, and PDFs in addition to audio

    and more: what each service (software or app) can do varies.

    2. Some Services Are Expensive
