Automated Telegram Voice Note Transcription with OpenAI

This n8n workflow automates the process of transcribing voice messages received via Telegram using OpenAI’s transcription capabilities. When a user sends a voice message in a Telegram chat, the workflow triggers automatically, downloads the audio file, transcribes it, and then sends back the text transcription to the same chat. This setup is useful for converting voice notes into written text for easier reference, archiving, or further processing. The workflow includes nodes for message detection, audio file retrieval, transcription via OpenAI, and sending the transcribed message back to the user. It is ideal for teams or individuals who want to streamline voice-to-text conversion directly within Telegram, enhancing communication productivity and record-keeping.
