AI Innovation: Bilingual Voice Support

AI Innovation is a real-time, voice-first customer-support assistant for Vietnamese- and English-speaking customers. It helps people explain common issues in their own language, see what the system has heard, and receive concise initial troubleshooting as spoken guidance. Customers can switch between Vietnamese and English during a conversation and interrupt a response whenever they need to clarify or add information. The browser streams microphone audio to a FastAPI server over WebSocket. The server relays it to AssemblyAI Streaming Speech-to-Text, forwarding partial and final transcripts to the interface. Gemini uses the conversation history and detected language as a hint to generate a reply. Edge TTS synthesizes completed sentences while the response is still being generated, so the assistant can begin speaking without waiting for the full answer. AI Innovation is a prototype, not a connected helpdesk. It cannot access customer accounts or orders, verify refund status, apply company-specific policies, or create support tickets. It is designed to be transparent about those limits, avoid asking for sensitive credentials, and direct account-specific issues to official human support. The current demo focuses on Vietnamese and English; connecting an approved knowledge base and secure human-support workflow is a future step.
