About this workflow
This n8n workflow processes incoming Telegram messages, differentiating between text and voice messages. How it works: 1. Message Trigger: The workflow initiates when a new message is received via the Telegram "Message Trigger" node. 2. Switch Node: This node acts as a router. It examines the incoming message: If the message is text, it directs the flow along the "text" branch. If the message contains voice, it directs the flow along the "voice" branch. 3. Get Audio File: For audio messages, this node downloads the audio file from Telegram. 4. Transcribe Audio: The downloaded audio file is then sent to an "OpenAI Transcribe Recording" node, which uses OpenAI's whisper-1 speech-to-text model to convert the audio into a text transcript. 5. Send Transcription Message: Regardless of whether the original message was text or transcribed audio, the final text content is then passed to a "Send transcription message" node. Setup Requirements: Telegram Bot Token: You will need a Telegram bot token configured in the "Message Trigger" node to receive messages. OpenAI API Key: An OpenAI API key is required for the "Transcribe audio" node to perform speech transcription. Additional Notes: This workflow provides a foundational step for building more complex AI-driven applications. The transcribed text or original text message can be easily piped into an AI agent (e.g., a large language model) for analysis, response generation, or interaction with other tools, extending the bot's capabilities beyond simple message reception and transcription. 👉 Need Help?
