Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Language learning applications rely on visual prompts and lack interactivity and real-time actionable feedback, falling short of providing an effective learning experience similar to in-person tutoring.
Innovation Solution
A system that uses audio input devices, speech recognition, and text-to-speech conversion to provide users with audible presentations, allowing them to respond audibly, with immediate feedback on pronunciation accuracy, and adjusting difficulty levels based on user performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If language learning apps use visual prompts and display screens for interaction, then users can access learning content conveniently, but the apps lack interactivity and real-time actionable feedback
Solution Approach 1:
The patent replaces visual display screen interaction with acoustic interaction. The system uses audio input devices to capture user speech and audio output devices to provide feedback, substituting the mechanical visual display system with an acoustic field-based system that enables hands-free operation and real-time feedback.
Solution Approach 2:
The system implements real-time feedback by capturing user speech through audio input devices, processing the speech data through speech recognition, comparing it with reference data, and immediately providing corrective feedback through audio output devices. This closed-loop feedback mechanism enables interactive learning without visual displays.
2Adaptability or versatility
If language learning provides in-person tutoring with real-time feedback, then interactivity and actionable correction are improved, but convenience and accessibility are reduced
Solution Approach 1:
The system enables self-service learning by providing automated speech recognition and feedback without requiring human instructors. The processor automatically compares user speech against reference data and generates corrective feedback, allowing users to learn independently with the same interactivity quality as in-person tutoring.
Solution Approach 2:
The system combines multiple functions into a single automated platform: speech capture, speech recognition, accuracy evaluation, and feedback generation. This multi-functional system delivers in-person tutoring quality interaction while maintaining the convenience of remote access.
3Measurement precision
If language learning requires physical interaction with input controls, then precision of input is improved, but hands-free interactivity and multitasking capability are reduced
Solution Approach 1:
The patent replaces physical input control interaction with acoustic input. Audio input devices capture speech signals directly, eliminating the need for physical button presses or keyboard typing. The speech recognition system processes these acoustic inputs with high accuracy, maintaining input precision while enabling hands-free operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables hands-free, interactive language learning with immediate feedback, mimicking in-person tutoring experiences while offering convenience and accessibility, allowing users to correct their pronunciation in real-time.
Implementation Method 1
A word or phrase spoken in a select language is detected by the audio input device and converted to a corresponding input electrical signal by the audio input device
Implementation Method 2
The system captures the speech data and converts the speech data into text data using a speech recognition system that analyzes the speech data
Implementation Method 3
The evaluated text data is converted back into an audio file with a text-to-speech conversion subsystem
Data Source
AI summary
A system and method for assisting a user in learning a target non-native language includes a processor executing instructions stored on a computer-readable medium, the executed instructions causing the processor to provide the user with an audible presentation of a word or a phrase in the target non-native language and prompting the user to audibly respond with speech data. The system captures the audible response and converts the audible response into input text data, then evaluates the text data for accuracy by comparing text characters in the text data to anticipated text data contained in a database. The system calculates the number of incorrect characters in the text data, then converts the evaluated text data into an output audio file and reads back the audio file to the user. The readback provided by the system provides audible feedback to the user regarding the accuracy of the evaluated text data.
