Aircraft Handset Speech Intelligibility Feedback via Vibration Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in airplanes struggle with assessing and improving speech intelligibility, as users are often unaware of their own speech clarity issues, leading to incomplete or prolonged communication due to reduced intelligibility.
Innovation Solution
A method and devices that analyze speech intelligibility using a control unit with a control program, providing alarm routines through vibration signals to alert users of poor speech clarity, allowing for immediate improvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If speech information data is transmitted between technical devices, then communication functionality is achieved, but speech intelligibility cannot be assessed by the user in real-time
Solution Approach 1:
The system analyzes speech information data exchanged between technical devices and provides feedback to the user through alarm routines when speech intelligibility falls below acceptable thresholds. This closed-loop feedback mechanism enables users to become aware of their speech quality issues in real-time and make immediate corrections.
Solution Approach 2:
A control unit with control program acts as an intermediary between the speech communication system and the user. It receives speech information data, performs intelligibility analysis, and translates the analysis results into user-comprehensible alarm routines, thereby bridging the gap between technical measurement and user perception.
2Productivity
If users speak without awareness of their speech clarity, then communication can proceed without interruption, but speech intelligibility deteriorates leading to incomplete communication
Solution Approach 1:
The alarm routine provides immediate feedback to users about their speech intelligibility, enabling them to self-correct without interrupting the overall communication flow. This maintains productivity while ensuring reliability by preventing incomplete communications caused by poor speech intelligibility.
Solution Approach 2:
The system replaces manual self-assessment of speech quality with automated acoustic analysis. The control unit objectively measures speech intelligibility parameters and compares them against predefined thresholds, eliminating the need for users to subjectively evaluate their own speech clarity.
3Measurement precision
If alarm routines are provided to alert users of poor speech intelligibility, then speech clarity can be improved, but additional processing and control mechanisms are required
Solution Approach 1:
The control unit with control program serves multiple functions: it manages the analysis of speech information data, determines intelligibility quality, decides when alarm routines should be triggered, and controls the delivery of feedback to users. This multi-functionality reduces the need for separate dedicated components for each function.
Solution Approach 2:
The system uses the existing speech information data already being transmitted between technical devices for analysis, rather than requiring separate microphones or sensors. The control unit leverages available communication infrastructure to perform intelligibility assessment without adding significant hardware complexity.
