🎙️ VoiceScribe AI: Telegram Audio Message Auto Transcription with OpenAI Whisper > Automatically transcribe Telegram voice messages and store them as structured logs in Google Sheets, while backing up the audio in Google Drive.

🧑‍💼 Who’s it for

- Journalists, content creators, or busy professionals who often record voice memos or short interviews on the go. - Anyone who wants to turn voice recordings into searchable, structured notes.

⚙️ How it works / What it does

1. User sends a voice message to a Telegram bot. 2. n8n checks if the message is an audio voice note. 3. If valid, it downloads the audio file and: - Transcribes it using OpenAI Whisper (or your LLM of choice). - Uploads the original audio to Google Drive for safekeeping. 4. The transcript and audio metadata are merged. 5. The workflow: - Logs the data into a Google Sheet. - Sends a formatted confirmation message to the user via Telegram.

If the input is not audio, the bot politely informs the user that only voice messages are accepted.
