Audio Classification & Emergency Detection

Overview#

The Audio domain provides real-time acoustic analysis capabilities designed for emergency response operations. It detects critical audio events such as gunshots, screams, explosions, and sirens in emergency call recordings or live audio streams, enabling faster response to life-threatening situations through automated audio analysis and risk scoring.

Key Features#

• Gunshot Detection -- Identifies gunshot acoustic signatures in audio streams with confidence scoring
• Scream and Distress Detection -- Recognizes high-pitch distress vocalizations to flag potential assault or emergency situations
• Explosion Detection -- Detects explosion signatures indicating immediate mass-casualty threats
• Siren Detection -- Identifies emergency vehicle siren patterns for situational context
• Risk Score Aggregation -- Produces a 0-100 risk score weighted by event severity for call prioritization
• Confidence Scoring -- Provides normalized confidence values (0.0-1.0) for each detected acoustic event
• Multi-Event Classification -- Analyzes audio for multiple simultaneous event types in a single pass
• Low-Latency Processing -- Delivers results quickly enough to support real-time emergency triage
• Body-Worn Camera Support -- Analyzes live audio from officer body-worn cameras for safety monitoring
• AI-Powered Audio Analysis -- Complements signal-based detection with AI transcription and sentiment analysis for deeper insight

Use Cases#

• Emergency call centers use audio classification to automatically flag high-risk 911 calls containing gunshots or screams, enabling dispatchers to prioritize life-threatening situations immediately.
• Body-worn camera audio streams are monitored in real time during active incidents to enhance officer safety through automated threat detection.
• Multi-modal call prioritization combines audio risk scores with text sentiment analysis and keyword detection to route calls to the appropriate priority level.
• Automated alerting systems use acoustic signature detection to trigger dispatcher notifications when critical audio events are identified.

Integration#

The Audio domain works with the PSAP operations module for emergency call triage, the sentiment analysis module for combined text and audio risk assessment, the body-worn camera module for real-time officer monitoring, and the prioritization engine for multi-modal call routing.
