Wireless Caption Communication Service System for Hearing-Impaired Conversations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional subtitle service systems are not suitable for daily conversations between hearing-impaired individuals and those without sign language knowledge, as they require sign language or writing, which are inefficient and inconvenient.
Innovation Solution
A wireless caption communication service system that includes a relay center, wireless caption communication device, and server, converting voice to text and text to speech in real-time, allowing hearing-impaired individuals to have face-to-face conversations without the need for sign language or writing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional subtitle service systems are used for daily conversations, then hearing-impaired individuals can access captioning, but the system requires sign language knowledge or writing skills from both parties, making communication inefficient and inconvenient
Solution Approach 1:
The patent introduces a relay center as an intermediary that converts spoken language to text and text to spoken language. This mediator handles the complexity of conversion processes, allowing direct communication between hearing-impaired individuals and others without requiring either party to learn sign language or write, thus improving ease of operation while managing system complexity through centralized processing
2Adaptability or versatility
If Telecommunication relay services are used for distance communication, then hearing-impaired individuals can communicate with others remotely, but the system is not suitable for everyday face-to-face communication
Solution Approach 1:
The patent creates a universal communication system that functions in multiple scenarios - both remote communication (like traditional relay services) and face-to-face conversation. The device can operate in different modes (speakerphone for distance, direct device display for close proximity) making it adaptable to various communication contexts while maintaining ease of operation through a unified interface
3Reliability
If sign language is used for communication, then hearing-impaired individuals can express themselves, but the other person must have knowledge of sign language, which is not always the case
Solution Approach 1:
The patent replaces the mechanical requirement of visual sign language gestures with an automated text-to-speech conversion system. The device captures spoken or typed input, converts it to text for display, and can also convert text back to speech output, eliminating the need for the other party to understand sign language while maintaining reliable communication effectiveness
4Reliability
If writing is used for communication, then both parties can exchange messages, but both persons must write and thus communication by writing is not effective or convenient
Solution Approach 1:
The patent implements a self-service communication system where the device automatically performs conversion tasks. The hearing-impaired individual only needs to type or speak, and the system automatically converts to text for display and can convert back to speech for the other party, eliminating the burden of requiring both parties to write manually while maintaining accurate communication

AI summary
A Wireless Caption Communication Service (“WCCS”) System includes a relay center, a wireless caption communication device, and a wireless captioning service server. The wireless caption communication device has a voice collecting device and a wireless caption communication terminal. Text entered by a first user is transmitted to the wireless captioning service server and converted into a speech. Then, the speech is transmitted to the voice collecting device and the sound of the speech comes out of a speaker of the voice collecting device so that a second user can hear the speech. The voice of the second user is transmitted to the wireless captioning service server and then to the relay center. The voice is converted into a caption data and transmitted to the wireless caption communication device, and the caption data is displayed on the wireless caption communication terminal so that the first user can read the caption data.
