​
Fraud Indicators

​
🎯 Audio Manipulation

Our system detects various forms of audio manipulation:
  • Audio Splicing: Detects when audio segments have been cut and reassembled
  • Voice Cloning: Identifies AI-generated or synthesized voices
  • Deepfake Detection: Recognizes sophisticated voice deepfakes
  • Background Noise Analysis: Identifies inconsistent or artificial background sounds

​
📝 Behavioral Patterns

Analysis of conversation patterns and behaviors:
  • Script Deviation: Detects when speakers deviate from expected protocols
  • Urgency Tactics: Identifies high-pressure tactics common in fraud
  • Information Gathering: Recognizes suspicious information extraction attempts
  • Emotional Manipulation: Detects psychological manipulation techniques

​
🔍 Voice Characteristics

Technical analysis of voice properties:
  • Voice Biometrics: Compares voice characteristics against known profiles
  • Stress Indicators: Detects stress patterns in speech
  • Consistency Analysis: Identifies inconsistencies in speaking patterns
  • Accent/Dialect Shifts: Recognizes unusual changes in speech patterns

​
Fraud Risk Scoring

Our comprehensive scoring system evaluates multiple factors:
  • Risk Levels
  • Score Components
Score RangeRisk LevelRecommended Action
0-20%Low RiskStandard review process
21-50%Medium RiskEnhanced review required
51-80%High RiskImmediate supervisor review
81-100%Critical RiskUrgent action required

​
Red Flags System

When red flags are detected, immediate review is recommended to prevent potential fraud losses.

​
Common Red Flags

What it means: The audio has been edited to remove or rearrange segmentsWhy it matters: Fraudsters may splice audio to:
  • Remove incriminating statements
  • Create false consent recordings
  • Manipulate conversation context
Action: Verify the original recording source and context
What it means: The voice may be artificially generated or clonedWhy it matters: Advanced AI can create convincing voice clones for:
  • Impersonation attacks
  • False authorization
  • Social engineering
Action: Implement multi-factor verification
What it means: The conversation follows known fraud script patternsWhy it matters: Fraudsters often use tested scripts for:
  • Phishing attempts
  • Account takeover
  • Financial fraud
Action: Flag for enhanced review and customer verification

​
Integration with Review System

The fraud detection system seamlessly integrates with our multi-reviewer workflow:

​
Best Practices

1

Regular Calibration

Regularly review and calibrate fraud detection thresholds based on your organization’s risk tolerance
2

Multi-Layer Verification

Don’t rely solely on AI - combine with human review for critical decisions
3

Continuous Training

Feed confirmed fraud cases back into the system to improve detection accuracy
4

Quick Response

Act quickly on high-risk alerts to minimize potential losses

​
API Integration

Integrate fraud detection into your existing systems: 
import requests

def analyze_audio_for_fraud(audio_file_path):
    with open(audio_file_path, 'rb') as f:
        response = requests.post(
            'https://api.authentivoice.com/v1/analyze',
            files={'audio': f},
            headers={'X-API-Key': 'your-api-key'}
        )
    
    result = response.json()
    fraud_score = result['fraud_indicators']['overall_score']
    
    if fraud_score > 80:
        trigger_high_risk_alert(result)
    
    return result
