Latency Metrics and Monitoring

​

Understanding Latency

What is Latency?

• Time between speech and response
• Measured in milliseconds
• Affects conversation flow
• Impacts user experience

Types of Latency

• Network latency
• Processing latency
• Response generation latency
• Total end-to-end latency

​

Monitoring Latency

Real-Time Monitoring

• Live latency metrics
• Dashboard display
• Alert thresholds
• Historical tracking

Latency Targets

• < 500ms: Excellent
• 500-1000ms: Good
• 1000-2000ms: Acceptable

• 2000ms: Needs improvement
