Conversation Analysis Device for Objective Role Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conversation analysis technologies lack objectivity in determining the roles of participants in group discussions, such as in classrooms or companies, as they rely on subjective evaluations rather than quantitative analysis of speech and influence.
Innovation Solution
A conversation analyzing device and method that acquires conversation data, analyzes speech amounts and influence, and determines roles based on quantitative index values such as facilitator, idea provider, and dominator levels, using sound source separation and voice recognition to objectively classify participants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If subjective evaluation by teachers or interviewers is used to determine participant roles, then evaluation can be carried out without complex analysis systems, but the evaluation results lack objectivity and proceedings must be interrupted for evaluation
Solution Approach 1:
The patent replaces the mechanical system of subjective human evaluation with an automated computer-based analysis system that processes conversation data, speech amounts, and influence metrics to objectively determine participant roles without requiring human intervention or interruption of proceedings
Solution Approach 2:
The analysis system performs self-evaluation by automatically processing conversation data and determining roles based on quantitative metrics, eliminating the need for external evaluators and allowing continuous proceedings without interruption
2Measurement precision
If quantitative analysis of speech amount and influence is performed to objectively determine roles, then objectivity is improved, but the complexity of data processing and analysis increases
Solution Approach 1:
The patent segments the complex analysis task into distinct components: speech amount analysis, influence analysis, and role determination. Each component processes specific metrics independently, making the overall complex analysis manageable and systematic
Solution Approach 2:
The patent introduces index values as intermediary metrics that bridge raw conversation data and final role determination. These index values (measuring speech amount, influence, facilitation, idea provision, and domination) simplify the analysis process by providing standardized measurement criteria
3Manufacturing precision
If multiple index values (facilitator level, idea provider level, dominator level) are calculated to determine roles, then role determination accuracy is improved, but the amount of computation and data processing increases
Solution Approach 1:
The patent uses multiple parameters (facilitator level, idea provider level, dominator level) to comprehensively characterize participant roles. Each parameter measures a different aspect of conversation behavior, and their combination enables accurate role classification through multi-dimensional analysis
Data Source
AI summary
A conversation data acquiring unit acquires conversation data indicating speech of each speaker in a conversation. A conversation state analyzing unit analyzes an amount of speech of each speaker in the conversation and a degree of influence of the speech of each speaker on the conversation on the basis of the conversation data. A role determining unit determines a role of each speaker in the conversation on the basis of the amount of speech and the degree of influence of the speaker.
