AI Live Call Insights Solution - Team Sahre

💡 Inspiration

Customer support agents handle 50+ calls daily but constantly struggle with accessing relevant information instantly, leading to frustrated customers, inconsistent responses, and missed opportunities. We witnessed firsthand how agents put customers on hold just to search for basic information, creating poor experiences that could cost businesses valuable relationships.

Our inspiration came from realizing that while AI can process and understand conversations in real-time, most support systems still operate like it's 1990. We envisioned a world where every support agent has an AI copilot that understands context, searches knowledge bases instantly, and provides perfect suggestions at exactly the right moment.

🎯 What it does

Sahre transforms live customer conversations into actionable insights through real-time AI assistance. Our solution:

Listens to live calls and provides real-time speech-to-text with speaker identification
Understands context using our dual-stage AI pipeline powered by Claude Sonnet 4
Searches knowledge bases instantly using RAG (Retrieval-Augmented Generation) with vector embeddings
Suggests perfect responses with contextual, actionable recommendation cards
Adapts to conversation flow - only showing suggestions when truly needed, preventing information overload
Scales across industries with modular knowledge base architecture

Key Innovation: Our intelligent filtering system evaluates conversation context before generating suggestions, ensuring agents receive relevant, timely guidance without overwhelming them.

🛠️ How we built it

Architecture & Tech Stack

Frontend: React with real-time WebSocket connections for live audio streaming
Backend: Node.js server handling WebSocket connections and AI orchestration
Speech Processing: AWS Transcribe for real-time speech-to-text with speaker diarization
AI Brain: Claude Sonnet 4 for intelligent suggestion generation and context evaluation
Knowledge Retrieval: Amazon Bedrock embeddings + vector similarity search
Storage: Amazon DynamoDB for session management and conversation analytics
Deployment: AWS Fargate with Application Load Balancer for auto-scaling

Two-Stage AI Pipeline

Evaluation Stage: AI determines if a suggestion is needed based on conversation context
Generation Stage: RAG system searches knowledge base and creates contextual recommendations

Real-time Processing Flow

Audio → Transcription → Context Analysis → Knowledge Search → Suggestion Generation → Display (all in <1 second)

⚡ Challenges we ran into

Technical Challenges

Real-time performance: Achieving sub-second response times while processing audio, running AI inference, and searching vector databases
WebSocket stability: Managing 100+ concurrent connections with reliable audio streaming
Context management: Maintaining conversation state and speaker identification across multiple turns
AI prompt engineering: Crafting prompts that generate consistently useful, concise suggestions

Integration Challenges

AWS service orchestration: Coordinating Transcribe, Bedrock, and DynamoDB for seamless real-time flow
Vector similarity tuning: Optimizing embedding search to return relevant knowledge chunks
Error handling: Building robust fallbacks for network issues, API failures, and audio quality problems

UX Challenges

Information overload prevention: Designing intelligent filtering to show only relevant suggestions
Real-time UI updates: Creating smooth, non-intrusive suggestion card animations
Multi-speaker handling: Accurately distinguishing between customer and agent voices
