Solution Overview

Problem

Educators face significant time burdens in recording attendance, grades, and other data, often relying on manual methods that are inefficient and prone to errors.

Innovation Solution

A voice-based grading assistant system that allows educators to dictate commands to a computing device, utilizing speech conversion, natural language processing, and a phoneme library to accurately enter and modify student and assignment data, correcting for misidentification of voice commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If educators manually enter records by hand or through computer-based applications, then data can be recorded, but the process consumes extensive time and is prone to errors

Engineering Contradiction:

Improvedata entry efficiencyVSAvoidtime spent on record keeping

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical data entry (writing by hand or typing) with voice-based speech recognition technology. Educators speak commands naturally, and the system automatically converts speech to text and executes the intended actions, eliminating the need for manual keyboard input and significantly reducing time consumption.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system enables self-service by allowing educators to interact with the grading platform through natural speech without requiring manual navigation of menus or forms. The voice commands automatically identify the educator, class, assignment, and student, and perform the grading action without requiring the educator to manually search or select from multiple options.

Inventive Principle:

Principle #25Self-service

2Productivity

If voice commands are used for data entry, then manual errors are reduced and efficiency increases, but misidentification of voice commands may occur

Engineering Contradiction:

Improvedata entry efficiencyVSAvoidaccuracy of voice command interpretation

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The system implements feedback by comparing the recognized speech against expected command structures and phoneme patterns. When a voice command is received, the system validates it against the phoneme library and provides confirmation or correction, ensuring accurate interpretation before executing the action. This feedback mechanism reduces misidentification while maintaining high productivity.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary action by pre-loading and organizing the phoneme library with expected voice commands and their corresponding meanings before actual grading occurs. This preparation allows the system to quickly and accurately match spoken commands to intended actions, reducing misidentification errors while maintaining efficient processing.

Inventive Principle:

Principle #10Preliminary action

AI summary

Disclosed are various embodiments of a voice-based grading assistant. A first computing device can receive a voice command from a second computing device that identifies an assignment, a student, and a grade for the student for the assignment. The voice command is then processed by the first computing device to identify the assignment, the student, and the grade. Subsequently, the first computing device can enter a grade for the student for the assignment in a data store.
