Agent Stress Detection via Audio-Visual Alignment During Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Contact center agents often experience exhaustion due to prolonged work hours or stressful calls, leading to reduced attention and quality of customer interactions, with limited options for tracking their need for breaks beyond scheduled intervals.
Innovation Solution
An AI-driven monitoring and triggering application (MTA AI/ML) analyzes audio and video features during calls to identify agent stress, providing destress breaks when certain emotional and facial thresholds are exceeded, and routing calls to another agent if necessary, using GPUs or CPUs for processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If AI-driven monitoring analyzes audio and video features during calls to identify agent stress, then agent well-being and customer satisfaction are maintained, but system complexity and processing requirements increase
Solution Approach 1:
The system segments the monitoring task into separate audio analysis and video analysis components, each processed independently by dedicated AI models. The audio processor analyzes stress indicators from speech patterns while the video processor analyzes facial expressions and body language, allowing parallel processing and reducing overall system complexity
Solution Approach 2:
The AI-driven monitoring system serves multiple functions simultaneously: it identifies agent stress levels, determines when destress breaks are needed, tracks compliance with break schedules, and provides data for quality assurance. This multi-functionality consolidates what would otherwise require separate systems into a single integrated platform
2Measurement precision
If AI monitoring continuously analyzes agent emotional states during calls, then stress detection accuracy improves, but processing time and computational resources increase
Solution Approach 1:
The system performs preliminary analysis by continuously monitoring audio and video streams in real-time during calls, pre-identifying stress indicators before thresholds are exceeded. This allows the system to prepare destress break recommendations in advance rather than reacting after stress has already impacted call quality
Solution Approach 2:
The patent replaces manual supervision and traditional stress detection methods with AI-driven automated analysis. Machine learning models process audio and video data to identify stress patterns, eliminating the need for human reviewers to manually analyze call recordings and reducing processing time from hours to seconds
3Reliability
If the system provides destress breaks to stressed agents, then agent exhaustion is reduced, but productivity and call handling capacity may decrease
Solution Approach 1:
The system implements continuous feedback loops where AI monitoring tracks agent stress levels in real-time, automatically triggering destress break recommendations when thresholds are exceeded. After breaks are taken, the system continues monitoring to verify stress reduction, creating a closed-loop system that adjusts future break recommendations based on observed effectiveness
Solution Approach 2:
The destress break system is dynamic rather than static: break duration and timing are adjusted based on real-time stress measurements, call priority levels, and agent performance history. The system can recommend shorter breaks for minor stress and longer breaks for severe exhaustion, optimizing the balance between agent well-being and productivity
Data Source
AI summary
A non-transitory computer-readable medium may store instructions readable by a processor for destressing an agent in a contract center. The instructions may cause the processor to run a monitoring and triggering application (“MTA”) to identify a state of stress of the agent. The MTA may run an artificial intelligence machine learning (“MTA AI/ML”) algorithm to identify the state of stress in which a first data stream feature (“first feature”) may have a first emotion of the agent that registers above a first feature threshold that corresponds to the first feature, and a second data stream feature (“second feature”) that is contemporaneous with the first feature may have a second emotion of the agent that is aligned with the first emotion of the agent when the first emotion registers above the first feature threshold and the second emotion, contemporaneous with the first emotion, registers above a second feature threshold.
