In short
One M4A audio file is enough for the support ticket. The engine reads it in Russian and writes the sections Ticket summary, Problem, Impact and urgency, and every line of the answer comes from the recording. The free plan gives 3 files a day.
How to get the file and turn it into a support ticket
- 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
Upload the file
The widget takes the file of the M4A audio file as it is and marks the speech as Russian, so the engine does not have to guess what it is about.
- 3
Ask the written instruction for the support ticket
The transcript of the M4A audio file goes to the instruction that is written for the support ticket, and the sections of the answer are Ticket summary, Problem, Impact and urgency.
- 4
Name the language of the speech
The recording of the M4A 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 support ticket follows.
- 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
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 M4A keeps, and what it says about it
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.
Google Drive keeps the M4A among the files it stores: any file type can be stored in Drive, and the list of the audio formats it previews names MP3, MPEG, WAV, .ogg and .opus.
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 case
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 Russian speech of the M4A audio file is read first, and the support ticket is what the support team gets out of the transcript.
Tips
A name that was never said in the M4A audio file stays out of the support ticket.
The language of the widget is the language of the M4A audio file.
A file over 30 minutes has to be cut into parts; the Pro plan takes a recording of any length.
Bots can currently send audio files of up to 50 MB in size, and the limit may be changed in the future.
