Voice Service Audio Frequency Adaptation for Age-Related Hearing Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice service devices have preset sound frequencies, which can be inconvenient for users with hearing obstacles, such as the elderly who struggle to hear high-frequency sounds, leading to difficulties in using these devices effectively.
Innovation Solution
An electronic device equipped with a microphone, processing unit, and speaker that analyzes voice messages to determine the user's age and adjust sound frequencies based on estimated hearing parameters, generating a response voice message tailored to the user's hearing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If preset sound frequency is used in voice service devices, then device complexity is reduced and ease of manufacture is improved, but adaptability to different user hearing states deteriorates
Solution Approach 1:
The patent implements dynamic sound frequency adjustment by analyzing user voice characteristics in real-time and adapting the output frequency accordingly. The processing unit dynamically modifies the frequency of voice responses based on detected voiceprint features, transforming a static preset system into a dynamic adaptive system that responds to individual user hearing capabilities.
Solution Approach 2:
The patent changes the sound frequency parameter based on user voice analysis. By extracting voiceprint data from the user's input and comparing it against reference data, the system adjusts the frequency parameter of the output voice message to match the user's hearing range, particularly optimizing for elderly users with high-frequency hearing loss.
2Device complexity
If voice service devices use fixed sound frequency, then device complexity is reduced, but ease of operation for users with hearing obstacles deteriorates
Solution Approach 1:
The system performs self-service by automatically analyzing the user's voice characteristics and adjusting the sound frequency without requiring manual input from the user. The processing unit autonomously detects voiceprint features, determines the appropriate frequency range, and modifies the voice output accordingly, making the device self-adapting to the user's hearing needs.
Solution Approach 2:
The patent implements a feedback mechanism where the user's voice input is analyzed to extract voiceprint data, which then feeds back into the system to adjust the output frequency. This closed-loop feedback allows the device to continuously adapt to the user's hearing characteristics, improving ease of operation for users with hearing impairments.
Data Source
AI summary
An electronic device capable of adjusting output sound is disclosed. The electronic device determines hearing state of a user by voiceprint recognition, and adjusts frequency of output sound, such that the output sound coincides with the hearing state of the user.
