Automated Audio Transcription with OpenAI

This n8n workflow facilitates seamless audio transcription by exposing a webhook to receive audio files. When an audio file is uploaded via the webhook, the workflow automatically sends it to OpenAI’s transcription API (GPT-4o-mini-transcribe model). The transcribed text is then extracted and sent back as a webhook response. Additionally, the workflow includes a comprehensive frontend HTML interface for recording audio directly in the browser, making it ideal for applications that require real-time speech-to-text conversion. This setup is perfect for developers building voice-enabled features, transcription services, or integrating voice notes into their applications.
