Voice Modification Program for Hearing-Impaired Telephone Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hearing-impaired individuals face difficulties distinguishing high-frequency sounds, particularly consonants and short words, during telephone conversations due to the removal of frequencies above 4000 Hz in traditional landline and internet phone transmissions.
Innovation Solution
An electronic device with a telephone function, comprising a processor, memory, microphone module, speaker, and voice signal communication module, uses a voice modification processing program to adjust and amplify sounds based on pre-set or dynamically obtained voice modification parameters, ensuring that hearing-impaired users can receive and understand voices with original frequencies above 4000 Hz.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If high-frequency sounds are removed from telephone transmission to reduce bandwidth requirements and improve signal quality, then transmission efficiency and signal clarity are improved, but hearing-impaired people cannot distinguish consonants and short sounds properly
Solution Approach 1:
The patent applies parameter changes by modifying the frequency parameters of the voice signal. Specifically, it uses voice modification parameters to adjust the frequency spectrum, shifting high-frequency consonant sounds to frequencies within the audible range for hearing-impaired people while maintaining transmission efficiency. This involves changing the frequency distribution of the voice signal rather than removing high-frequency components entirely.
Solution Approach 2:
The patent introduces an intermediary voice modification processing program that acts as a mediator between the original voice signal and the transmitted signal. This processing program, stored in the electronic device, modifies the voice parameters before transmission and can reverse or adjust them at the receiving end, thereby serving as an intermediary that bridges the gap between standard telephone transmission and hearing-impaired accessibility.
2Reliability
If voice modification parameters are processed in real-time during telephone conversations, then communication clarity for hearing-impaired people is improved, but processing time and computational complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-storing voice modification parameters in the electronic device before the actual telephone conversation occurs. The processing program is prepared in advance with the necessary parameters, allowing for rapid application during the call without significant processing delays. This pre-preparation reduces the computational burden during real-time communication.
Solution Approach 2:
The electronic device performs self-service by automatically obtaining and applying voice modification parameters without requiring manual intervention from the user. The system autonomously processes the voice signals using pre-configured parameters, eliminating the need for users to manually adjust settings while maintaining communication clarity for hearing-impaired individuals.
3Adaptability or versatility
If voice modification parameters are obtained and applied dynamically based on caller ID, then adaptability to different hearing-impaired users is improved, but system complexity and data management requirements increase
Solution Approach 1:
The system performs self-service by automatically obtaining voice modification parameters based on the caller ID without requiring manual configuration. The electronic device autonomously identifies the user and applies the appropriate parameters, reducing the need for complex manual setup while maintaining user-specific adaptability. This automation simplifies the overall system operation despite the complexity of parameter management.

AI summary
A method of processing telephone voice output is applied in an electronic device with telephone function. When any one of the two communicators is a hearing-impaired user, at least one of the electronic devices will obtain the corresponding voice adjustment parameters according to the receiver identification of the hearing-impaired user. Therefore, the voice adjusting program is able to process the voice in advance based on the voice adjustment parameters to help the hearing-impaired user hear better.
