Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Individuals with hearing loss or speech disorders face challenges in producing clear and accurate speech due to the inability to hear their own voice, leading to difficulties in communication and reluctance to speak, which is exacerbated by the high cost and limited accessibility of existing solutions like cochlear implants and speech therapy.

Innovation Solution

An AI-powered software integrated with smartphones or wearable devices that converts unclear speech to clear speech, utilizing personalized speech recognition models and self-training tools to mimic the user's voice characteristics, providing real-time feedback and guidance for improved pronunciation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If speech therapy training is provided to improve speech clarity, then speech quality can be improved, but the process becomes long and costly

Engineering Contradiction:

Improvespeech qualityVSAvoidtraining duration

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The system creates a digital copy of the user's voice characteristics through voice printing technology, capturing pitch, tone, and timbre. This voice model is then used to generate clear speech from text, eliminating the need for lengthy traditional speech therapy while preserving the user's natural voice identity.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical process of manual speech therapy with an automated AI system. The voice printing and text-to-speech generation system automatically analyzes and generates clear speech without requiring human speech therapists, thereby reducing both time and cost while maintaining speech quality improvement.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If traditional speech therapy is used to improve speech clarity, then speech quality can be improved, but the cost becomes high

Engineering Contradiction:

Improvespeech qualityVSAvoidcost

Core Design Contradiction:

Manufacturing precisionVSEase of manufacture

Solution Approach 1:

Inventive Principle:

Principle #26Copying

Solution Approach 2:

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Ease of operation

If people with hearing loss speak using their own voice after training, then communication convenience is improved, but speech clarity becomes insufficient

Engineering Contradiction:

Improvecommunication convenienceVSAvoidspeech clarity

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The system introduces an intermediary AI processing layer between the user's text input and spoken output. The user types text, the system processes it through the voice model to generate clear speech with correct pronunciation, and outputs the improved speech. This intermediary process enhances speech clarity while maintaining communication convenience.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

Inventive Principle:

Principle #26Copying

4Reliability

If cochlear implants are used to treat hearing loss, then hearing capability is improved, but accessibility becomes limited due to high cost

Engineering Contradiction:

Improvehearing capabilityVSAvoidaccessibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent replaces expensive medical devices like cochlear implants with an software-based AI system. The voice printing and text-to-speech technology provides hearing and speech assistance through standard smartphones and wearables, making the solution accessible to millions of people who cannot afford cochlear implants while maintaining effective communication capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
