How it works

  2. 2

    Attach the recording

    The file of the M4A audio file is attached in the widget of this page, and the speech is marked as English; the answer comes back as the task list.

  3. 3

    Turn the text into the task list

    The text of the M4A audio file is given to the instruction of the task list, and the answer is written in the sections Topic, Tasks, Ideas for later, one after another.

  4. 4

    Set the language of the speech

    The speech of the M4A audio file is English, one of the 99+ languages the engine reads, and the widget is left on English while the task list is written.

  5. 5

    Check the file before the upload

    In the FAQ of the FFmpeg library of Audacity the M4A is written next to the codec it carries: M4A (AAC), AC3 and WMA

The result

What comes back from the engine

  • TXT

    One segment per line, the way a person wrote it down. It is the format to paste into a ticket, a chat or a document.

  • TXT, CSV

    The start and the end time of every segment, and the speakers named separately when you ask for it.

  • SRT, VTT

    SRT and VTT with the time of every line, so the recording can carry its own subtitles.

  • Markdown, DOCX

    The transcript is edited through the API and exported as Markdown for a wiki, or as DOCX for a review.
