Integrating Exotel with OpenAI: Building a Voicebot in n8n

Handling audio streams can be a real challenge when building voicebots. But what if you could set up a webhook from Exotel, process speech-to-text with Whisper, and generate a natural response in under 2 seconds? That’s exactly what I did with our recent Voice AI project.

Here’s a step-by-step guide on how I integrated Exotel with OpenAI using n8n:

• Setup the Exotel webhook to receive audio streams
• Use Whisper for speech-to-text processing
• Feed the output into an n8n workflow to generate a natural response
