Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Assessing voice quality in VoIP networks is challenging due to the difficulty in measuring degradation caused by network elements, which affects the intelligibility of speech transmission, and existing methods are inefficient and costly for network design and troubleshooting.
Innovation Solution
A method and apparatus that input reference speech samples into a communication system, using a voice analysis platform to generate voice quality scores by analyzing captured samples at various points, allowing for objective measurement and graphical display of voice quality statistics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional subjective and/or objective voice quality analysis methods are used between two endpoints, then voice quality scores can be generated, but obtaining these scores at various points along the network is difficult and inefficient
Solution Approach 1:
The patent introduces a voice quality assessment device as an intermediary component that can be deployed at various points along the network path. This device captures speech samples, processes them through voice quality assessment algorithms, and generates scores without requiring endpoint participation. The intermediary device bridges the gap between network infrastructure and quality measurement, enabling objective assessment at multiple locations.
Solution Approach 2:
The patent replaces traditional subjective human evaluation methods with automated objective voice quality assessment algorithms. The system uses computational processing to analyze speech samples and generate quality scores, substituting manual subjective analysis with automated mechanical/electronic assessment systems that can operate continuously and objectively at network points.
2Ease of manufacture
If VoIP networks are deployed to reduce capital costs, then lower implementation costs are achieved, but the ability to easily and objectively measure degradation of voice service quality by network elements is lost
Solution Approach 1:
The voice quality assessment device serves as an intermediary monitoring system that objectively measures voice quality degradation at various network points. It captures speech samples, processes them through assessment algorithms, and identifies which network elements contribute to quality degradation, providing the measurement capability that was lost in VoIP deployments.
Solution Approach 2:
The system implements feedback by continuously monitoring voice quality scores at different network points and providing information about degradation sources. This feedback mechanism enables network operators to identify problematic elements and make informed decisions about network optimization and troubleshooting.
3Reliability
If pre-deployment network assessment is attempted, then VoIP performance can be evaluated prior to deployment, but the process becomes extremely difficult
Solution Approach 1:
The patent enables preliminary voice quality assessment by deploying the assessment device before full VoIP service deployment. The device can evaluate network performance characteristics, identify potential quality issues, and provide baseline measurements that inform deployment decisions. This preliminary action allows network operators to assess VoIP performance under controlled conditions before committing to full deployment.

AI summary
One or more methods and systems of analyzing, assessing, and reporting voice quality scores are presented. In one embodiment, voice quality scores are generated by querying one or more computing devices responsible for processing a reference speech sample input into a voice communication system. In one embodiment, voice quality scores are transmitted by a voice analysis platform and subsequently analyzed. In one embodiment, a single voice analysis platform is used to measure voice quality of a voice communication system. In one embodiment, multiple voice analysis platforms are used to measure voice quality at multiple endpoints of one or more voice communication systems. In one embodiment, the method comprises a user determining one or more points along a communication system where transmitted reference speech samples are to be tapped. The tapped reference speech samples are ported to a voice analysis platform where a voice quality score is generated and graphically displayed.
