👉 Click here to follow our complete step-by-step tutorial and learn how to build this from scratch with detailed code walkthroughs, explanations, and best practices.

An OpenAI SDK powered customer support agent application that delivers voice-powered responses to questions about your knowledge base using OpenAI's GPT-4o and TTS capabilities. The system crawls through documentation websites with Firecrawl, processes the content into a searchable knowledge base with Qdrant, and provides both text and voice responses to user queries.

Features

• Knowledge Base Creation

  • Crawls documentation websites using Firecrawl
  • Stores and indexes content using Qdrant vector database
  • Generates embeddings for semantic search capabilities using FastEmbed

• AI Agent Team

  • Documentation Processor: Analyzes documentation content and generates clear, concise responses to user queries
  • TTS Agent: Converts text responses into natural-sounding speech with appropriate pacing and emphasis
  • Voice Customization: Supports multiple OpenAI TTS voices:
    • alloy, ash, ballad, coral, echo, fable, onyx, nova, sage, shimmer, verse

• Interactive Interface

  • Clean Streamlit UI with sidebar configuration
  • Real-time documentation search and response generation
  • Built-in audio player with download capability
  • Progress indicators for system initialization and query processing
