In short

What the M4A stores is what the engine needs. The English speech becomes the minutes in the sections Attendees, Agenda, Discussion by item; one file may be up to 30 minutes, and 3 files a day are free.

How it works

How to get the file and turn it into file

  1. 1

    Open it in an audio program

    The FFmpeg library of Audacity imports a much larger range of audio formats, including AC3, M4A, MP4 and WMA, so an M4A of a phone is opened with it

  2. 2

    Upload the file

    The file of the M4A audio file is sent as an attachment; the language of the speech is English, and the minutes comes back in the export of the service.

  3. 3

    Ask the written instruction for the minutes

    The instruction of the task asks for the minutes and puts the answer about the M4A audio file into the sections Attendees, Agenda, Discussion by item; a claim that is not in the recording is not written.

  4. 4

    Name the language of the speech

    The engine reads 99+ languages; this M4A audio file is in English, so the language of the widget is set to English for the minutes.

  5. 5

    Check the file before the upload

    A voice message of the Telegram Bot API is an .OGG file encoded with OPUS, an .MP3 file or an .M4A file

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.

What the recording does not give you

The Telegram Bot API takes an audio file only in the .MP3 or .M4A format, and it sends a voice message in the .OGG file encoded with OPUS, .MP3 or .M4A format. the M4A is only the place where the recording waits; the text and the minutes are made by the engine, in English.
