In short

What the PCM stores is what the engine needs. The Russian speech becomes the revision deck in the sections Cards, Terms to define, Self-check questions; 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 flashcards for revision

  1. 1

    Record it in a container

    In OBS Studio the PCM audio is recorded in the MP4, MOV and MKV containers

  2. 2

    Send the file to the engine

    The recording of the PCM audio file is attached to the widget of the page with the language of the speech set to Russian, and the revision deck comes back as a file of text.

  3. 3

    Ask the written instruction for the revision deck

    The instruction that is set for this task goes through the transcript of the PCM audio file and writes the revision deck in the sections Cards, Terms to define, Self-check questions; nothing is added that was not said.

  4. 4

    Mark the language of the speech

    The recording of the PCM audio file is in Russian, and that is one of the 99+ languages the engine reads; the setting of the widget says Russian and the revision deck follows.

  5. 5

    Check the file before the upload

    LPCM stands in the list of the audio formats of the VLC player, next to AMR (3GPP) and ADPCM

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.
