Voice Analysis Module for Objective Customer Service Quality Measurement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for measuring customer service quality are subjective and unreliable, with low survey response rates and biased results due to vocal customers skewing satisfaction ratings, making it difficult to objectively assess service quality across diverse interactions.
Innovation Solution
A system that captures and analyzes digitized voice segments to determine emotion levels and generate a customer service score through voice feature extraction and normalization, using a voice analysis module to assess changes in emotion levels and provide feedback for improving service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual surveys are used to measure customer satisfaction, then customer feedback can be collected, but response rates are low and results are biased by vocal customers
Solution Approach 1:
The patent replaces the manual survey mechanism with an automated voice analysis system that uses acoustic signal processing to detect customer emotions. Instead of relying on customers to manually fill out surveys, the system automatically analyzes voice characteristics during calls to determine satisfaction levels, eliminating response rate issues and vocal customer bias.
Solution Approach 2:
The system enables customers to provide satisfaction feedback passively through their natural voice interactions during service calls. Customers do not need to consciously participate in feedback collection; their voice emotions are automatically analyzed and processed into satisfaction metrics without requiring their active engagement in the measurement process.
2Quantity of substance
If survey response rates are increased by encouraging more customers to participate, then more data is collected, but the silent majority remains underrepresented and bias persists
Solution Approach 1:
The voice analysis system operates continuously throughout customer service calls, collecting emotional data from every interaction regardless of customer willingness to participate in surveys. This continuous measurement approach ensures that all customers, including the silent majority, are automatically included in the feedback data without requiring active participation.
3Measurement precision
If automated voice analysis is implemented to objectively measure service quality, then measurement precision improves, but system complexity increases
Solution Approach 1:
The patent introduces a voice analysis module as an intermediary component that bridges customer service calls and quality measurement. This modular intermediary processes voice signals through standardized acoustic feature extraction and emotion detection algorithms, providing objective measurements without requiring complex integration into the existing customer service infrastructure.

AI summary
Methods and apparatuses are described for determining customer service quality through digitized voice characteristic measurement and filtering. A voice analysis module captures a first digitized voice segment corresponding to speech submitted by a user of a remote device. The voice analysis module extracts a first set of voice features from the first voice segment, and determines an emotion level of the user based upon the first set of voice features. The voice analysis module captures a second digitized voice segment corresponding to speech submitted by the user. The voice analysis module extracts a second set of voice features from the second voice segment, and determines a change in the emotion level of the user by comparing the first set of voice features to the second set of voice features. The module normalizes the change in the emotion level of the user using emotion influence factors, and generates a service score.
