Intelligent Interruption Handler Solution

Problem Solved

Agent now distinguishes between passive acknowledgments ("yeah", "okay") and real interruptions ("stop", "wait") based on agent state.

Core Logic Implemented

User Says	Agent State	Behavior	Status
"yeah/okay"	Speaking	Ignores, continues	✅
"stop/wait"	Speaking	Stops immediately	✅
"yeah/okay"	Silent	Responds normally	✅

Key Features

• No pause/stutter - Seamless continuation using session.resume()
• State-aware - Tracks agent_speaking boolean
• Configurable - Word lists via .env environment variables
• Semantic detection - "Yeah but wait" correctly stops (detects "wait")

Technical Implementation

• Three-layer approach: VAD tuning + transcript filtering + auto-resume
• Handles VAD false starts with was_vad_interrupted flag
• Processes interim transcripts for instant detection
• Zero-delay resume for seamless flow

All Test Scenarios Pass

1. Long explanation + "yeah" → Agent continues
2. Silent + "yeah" → Agent responds
3. Speaking + "stop" → Agent stops
4. Speaking + "yeah but wait" → Agent stops
