The system uses LiveKit Agents for real-time audio, Murf Falcon for fast speech synthesis, and supports code-mixed Hinglish conversations, persistent memory, and counselor escalation. The developer shared the codebase on GitHub.", "body_md": "Introduction: The Problem & The Vision\n\nNavigating academic roadmaps, entrance exams, admissions, and financial aid can be an overwhelming journey for students across India. Text-heavy portals, complex application forms, and confusing documentation guides often create barriers rather than bridges.\n\nTo bridge this gap, I built **EduGuideAI**—an interactive, ultra-low-latency voice assistant designed to guide students and parents through their educational queries naturally. Built during the **10 Days of Voice Agents — #VoiceForBharat Challenge by Murf AI**, EduGuideAI moves beyond traditional chatbots by holding real-time, code-mixed (Hinglish/English) spoken conversations, executing live database checks, remembering student context, and escalating complex inquiries to human counselors.\n\n###\nHow EduGuideAI Works (System Architecture)\n\nA smooth voice experience requires near-instantaneous streaming across four primary stages:\n\n-\n**Audio Transport:** Real-time WebRTC audio handling via **LiveKit Agents**.\n-\n**Speech Recognition (STT):** Captures accents, terms, and conversational student phrasing.\n-\n**Reasoning & Tool Execution:** LLM loaded with academic guardrails, student profile memory, and functional tools.\n-\n**Voice Synthesis (TTS):** **Murf Falcon** — delivering lightning-fast streaming audio with natural, clear Indian pronunciation.\n\n###\nKey Features Built into EduGuideAI\n\n####\n1. Instant Indian Voice with Murf Falcon\n\nAcademic guidance requires an empathetic, reassuring, and articulate tone. With **Murf Falcon**, response latency stays under 800ms, making conversations feel natural and fluid without awkward pauses.\n\n####\n2. Guardrails & Code-Mixed (Hinglish) Support\n\nStudents often mix Hindi and English when asking questions (e.g., *\"Is college ke admission criteria kya hain?\"*). EduGuideAI naturally parses code-mixed queries while staying strictly within safe academic boundaries, preventing hallucinations on critical details like deadlines and fee structures.\n\n####\n3. Persistent Memory & Real-Time Student Tools\n\n-\n**Dynamic Information Retrieval:** Fetches live details regarding courses, deadlines, and documentation checklists mid-dialogue.\n-\n**Student Context Memory:** Remembers returning students' previous queries, target fields of study, and application stages.\n\n####\n4. Outbound Telephony & Counselor Escalation\n\n-\n**Outbound Updates:** Initiates reminder calls for upcoming application deadlines or documentation verification.\n-\n**Human Counselor Handoff:** Cleanly routes sensitive counseling or specialized career discussions to human advisors along with the conversation summary.\n\n###\nEngineering Challenges & Solutions\n\n-\n**Handling Backchannel Cues & Interruptions:**\n\n-\n*Problem:* Students often interject with acknowledgments like *\"haan\"*, *\"samjha\"*, or *\"okay\"* while the bot is explaining a process.\n-\n*Solution:* Fine-tuned Voice Activity Detection (VAD) thresholds in LiveKit to distinguish casual backchannel listening cues from true user interruptions.\n\n-\n**Mitigating Latency During Database Queries:**\n\n-\n*Problem:* Awaiting API responses for course or cutoff lists created silent gaps.\n-\n*Solution:* Configured EduGuideAI to emit conversational filler phrases (e.g., *\"Checking the latest guidelines for you...\"*) while asynchronously fetching tool data.\n\n###\nHow to Run EduGuideAI Locally\n\nInspect the complete codebase on GitHub:\n\n👉 [murf-livekit-starter Repository](https://github.com/ayushthakur-bit/murf-livekit-starter)\n\n####\n1.
