+<h1>LiveKit Intelligent Interruption Handling 
+Challenge </h1>
+
+<h2>🚀 Overview</h2>
+<p>
+This project implements a <b>context-aware interruption handling system</b> for a real-time voice AI agent using the LiveKit framework.
+</p>
+
+<p>
+Traditional voice agents incorrectly treat small acknowledgements like <i>"yeah", "ok"</i> as interruptions.  
+This system intelligently distinguishes between <b>passive acknowledgements</b> and <b>active interruptions</b>.
+</p>
+
+<hr>
+
+<h2>🧠 Problem Statement</h2>
+<ul>
+  <li>Users often say filler words while listening</li>
+  <li>Default VAD interprets them as interruptions</li>
+  <li>Agent stops speaking unnecessarily ❌</li>
+</ul>
+
+<p><b>Goal:</b> Build a system that understands user intent and reacts correctly.</p>
+
+<hr>
+
+<h2>⚙️ System Architecture</h2>
+<pre>
+User Voice → VAD → STT → classify_input() → Decision → Agent Action
+</pre>

+<h2>📄 File Explanation</h2>
+
+<h3>🔹 main.py</h3>
+<ul>
+  <li>Initializes the agent session</li>
+  <li>Connects VAD, STT, LLM, TTS</li>
+  <li>Registers event handlers</li>
+</ul>
+
+<p><b>Role:</b> Main controller of the system</p>
+
+---
+
+<h3>🔹 interrupt_handler.py</h3>
+<p>Core decision-making logic:</p>
+
+<pre>
+classify_input(text, is_agent_speaking)
+</pre>
+
+<p>Returns:</p>
+<ul>
+  <li><b>IGNORE</b> → continue speaking</li>
+  <li><b>INTERRUPT</b> → stop agent</li>
+  <li><b>RESPOND</b> → normal reply</li>
+</ul>
+
+---
+
+<h3>🔹 state_manager.py</h3>
+<ul>
+  <li>Tracks agent state</li>
+  <li>Maintains: <code>is_agent_speaking</code></li>
+</ul>
+
+---
+
+<h3>🔹 transcript_handler.py</h3>
+<ul>
+  <li>Processes user speech</li>
+  <li>Calls decision logic</li>
+  <li>Executes actions</li>
+</ul>
+
+<hr>
+
+<h2>🧪 Scenarios & Solutions</h2>
+
+<h3>✅ Scenario 1: Long Explanation</h3>
+<p><b>Input:</b> "yeah okay hmm"</p>
+<p><b>Result:</b> Agent continues speaking (IGNORE)</p>
+
+---
+
+<h3>✅ Scenario 2: Passive Affirmation</h3>
+<p><b>Input:</b> "yeah" (when silent)</p>
+<p><b>Result:</b> Agent responds normally (RESPOND)</p>
+
+---
+
+<h3>✅ Scenario 3: Correction</h3>
+<p><b>Input:</b> "no stop"</p>
+<p><b>Result:</b> Agent stops immediately (INTERRUPT)</p>
+
+---
+
+<h3>✅ Scenario 4: Mixed Input</h3>
+<p><b>Input:</b> "yeah okay but wait"</p>
+<p><b>Result:</b> Agent stops (INTERRUPT)</p>
+

+
+<h2>⚡ Key Features</h2>
+<ul>
+  <li>Context-aware interruption handling</li>
+  <li>Real-time decision making</li>
+  <li>Handles mixed and noisy speech inputs</li>
+  <li>Modular architecture</li>
+</ul>
+
+<hr>
+
+<h2>🔑 Technologies Used</h2>
+<ul>
+  <li>LiveKit Agents</li>
+  <li>Groq LLM (LLaMA 3.1)</li>
+  <li>Deepgram (STT)</li>
+  <li>ElevenLabs / Cartesia (TTS)</li>
+  <li>Python (Async Programming)</li>
+</ul>
+

+
+<h2>▶️ How to Run</h2>
+<pre>
+pip install -e .
+pip install -r requirements.txt
+python main.py console
+</pre>
+
+<hr>
+
+<h2>🎤 Test Commands</h2>
+<pre>
+yeah okay hmm   → IGNORE
+no stop         → INTERRUPT
+yeah            → RESPOND
+hello           → RESPOND
+</pre>
