Who is this workflow for? This n8n workflow enables the creation of sophisticated voice-based chat applications. It leverages Webhooks, Memory Management, and AI services like OpenAI, Google Gemini, and ElevenLabs to deliver dynamic, context-aware conversations through voice interactions..

What does this workflow do?

  • Receive Audio Input: The workflow starts with a Webhook node that listens for incoming HTTP Post requests containing voice messages.
  • Transcribe Audio: The audio input is sent to OpenAI for speech-to-text transcription, converting the voice message into text.
  • Process Conversation: The transcribed text is processed using Google Gemini (or alternatively OpenAI), which generates a context-aware response based on the conversation history stored in the Memory Manager.
  • Convert Text to Speech: The generated response text is sent to ElevenLabs, which converts it back into speech.
  • Respond via Webhook: The audio response is sent back through the Webhook, completing the voice interaction loop.
  • Manage Memory: The Memory Manager ensures that the context of the conversation is maintained across multiple interactions, enabling more coherent and relevant responses over time.
