Solution Overview

Problem

Conventional voice conference devices lack the ability to objectively measure participant contribution to discussions, leading to reduced motivation for efficient participation.

Innovation Solution

A conversation analysis device and method that acquires and analyzes utterance data to calculate a degree of contribution for each speaker based on speech state, including activity, interruption, and conclusion mentions, providing an evaluation of contribution and activity levels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional voice conference devices are used, then basic voice recording and playback functions are provided, but the ability to objectively measure participant contribution is lacking

Engineering Contradiction:

Improvecontribution measurement capabilityVSAvoidsystem structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The voice conference device is enhanced with multiple analysis functions including speech state analysis, degree of contribution calculation, and conversation evaluation, allowing a single device to perform both basic voice recording and comprehensive contribution measurement without requiring separate systems

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

A conversation analysis device acts as an intermediary component between the voice conference device and users, processing utterance data and providing objective contribution measurements without fundamentally altering the core voice conference functionality

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If no contribution measurement is provided, then the system remains simple, but participant motivation for efficient discussion decreases

Engineering Contradiction:

Improvediscussion efficiencyVSAvoidsystem simplicity

Core Design Contradiction:

ProductivityVSEase of operation

Solution Approach 1:

The system provides real-time feedback to participants through degree of contribution calculations and conversation evaluation results, enabling users to understand their participation levels and adjust their discussion strategies to improve overall efficiency

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

Subjective assessment of participant contribution is replaced with automated computational analysis of speech states and utterance patterns, using algorithms to objectively measure and evaluate discussion participation without manual intervention

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If speech state analysis is added to analyze contribution, then contribution measurement capability is improved, but device complexity increases

Engineering Contradiction:

Improvespeech state analysis capabilityVSAvoidanalysis processing complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The speech state analysis process is divided into distinct functional modules including utterance data acquisition, speech state analysis, degree of contribution calculation, and conversation evaluation, allowing each module to be developed and optimized independently while maintaining overall system coherence

Inventive Principle:

Principle #1Segmentation

AI summary

A conversation analysis device includes an utterance data acquisition unit that acquires utterance data representing a voice of each speaker and an utterance of the speaker, a speech state analysis unit that analyzes a speech state of each speaker on the basis of the voice, and a degree-of-contribution calculation unit that calculates a degree of contribution to the conversation of each speaker on the basis of the speech state.
