Voice Assistant Interface with OpenAI GPT-4o-mini & TTS

This n8n workflow creates a fully functional voice assistant that runs in the browser, allowing users to interact via speech. Click a glowing animated orb to start recording, and the system transcribes audio using the Web Speech API, processes it through OpenAI's GPT-4o-mini model with conversation memory, and responds with synthesized voice via OpenAI TTS. It's designed for easy deployment with a webhook-based backend.

Key benefits include rapid prototyping of voice interfaces without custom coding, cost-effective AI integration, and persistent session memory for contextual conversations. It saves developers weeks of frontend/backend development time and leverages modern browser APIs for broad compatibility (Chrome, Edge, Safari).

Ideal use cases: Enhance customer support with voice bots, create interactive demos for content creators, build Alexa-like assistants for apps, or prototype voice-enabled dashboards. Customize by swapping AI models, adding tools to the agent, or styling the UI. Setup is straightforward: import workflow, add OpenAI API key, configure webhook URLs, and access via browser.
