Avatar Interaction Assessment System Using Speech and Motion Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated assessment tools lack the ability to efficiently and reliably evaluate a person's interaction skills with multimodal data, such as speech and body language, in contexts like teacher licensure and professional development, as they often fail to provide consistent and scalable evaluations.
Innovation Solution
A system that captures and analyzes speech and motion data from interactions with an interactive avatar, using automatic speech recognition and motion capture to determine a subject's score based on their communication effectiveness, incorporating features like fluency, intonation, and body posture analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated assessment tools are implemented to evaluate interaction skills, then evaluation efficiency and scalability are improved, but reliability and consistency of evaluations deteriorate
Solution Approach 1:
The assessment system segments interaction evaluation into multiple independent modalities including speech recognition, body language analysis, and facial expression detection. Each modality is processed separately through dedicated algorithms, allowing comprehensive evaluation while maintaining consistency through standardized processing pipelines for each segment.
Solution Approach 2:
The system implements feedback mechanisms where assessment results are continuously refined based on multiple data sources. The evaluation process incorporates real-time feedback from speech patterns, motion capture data, and facial expressions, allowing the system to adjust and improve evaluation consistency while maintaining high processing efficiency.
2Measurement precision
If multimodal data analysis is used to assess communication effectiveness, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system employs a unified multimodal analysis platform that handles multiple types of data (speech, motion, facial expressions) through a single integrated framework. This universal system performs various assessment functions including fluency analysis, body language interpretation, and emotional state detection, reducing overall system complexity while maintaining high measurement precision across different interaction dimensions.
Solution Approach 2:
The system introduces intermediary processing layers that translate complex multimodal data into standardized features for analysis. These intermediaries include speech-to-text conversion modules, motion capture processing units, and facial expression recognition algorithms that bridge raw data and final assessment metrics, simplifying the overall system architecture while preserving measurement precision.

AI summary
Systems and methods are provided for acquiring physical-world data indicative of interactions of a subject with an avatar for evaluation. An interactive avatar is provided for interaction with the subject. Speech from the subject to the avatar is captured, and automatic speech recognition is performed to determine content of the subject speech. Motion data from the subject interacting with the avatar is captured. A next action of the interactive avatar is determined based on the content of the subject speech or the motion data. The next action of the avatar is implemented, and a score for the subject is determined based on the content of the subject speech and the motion data.
