Telecommunication Terminal Audio Status Conversion via Direct Link
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telecommunication systems for visually impaired users require expensive special hardware to convert terminal status information into audio, and there is a need for a cost-effective method to provide this information without compromising network security.
Innovation Solution
A method and apparatus that establish a direct connection between a monitor computer and a telecommunication terminal to convert terminal status information into audio, using a firewall to prevent unauthorized network access, allowing for the presentation of visual terminal status information as audio to the user without connecting to the network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If special hardware is used to convert terminal status information to audio information, then audio information is provided to visually impaired users, but the cost becomes expensive
Solution Approach 1:
The patent uses software to create a virtual copy of the voice synthesis functionality that exists in standard telecommunication terminals. Instead of requiring specialized hardware, the system captures terminal status information and reconstructs audio output through software-based voice synthesis on ordinary computers, eliminating the need for expensive specialized hardware while maintaining audio information provision capability
Solution Approach 2:
The invention leverages the existing multi-functional capabilities of standard telecommunication terminals and personal computers. These devices already possess audio output capabilities, processing power, and communication interfaces. The patent makes them universally applicable for accessibility purposes by adding software that enables voice synthesis and audio conversion, allowing ordinary devices to serve visually impaired users without requiring dedicated specialized equipment
2Reliability
If special hardware is connected between the telephone set and the telecommunication system, then audio information is provided, but the device complexity increases
Solution Approach 1:
The patent extracts the audio conversion functionality from specialized hardware and relocates it to software running on existing telecommunication terminals. By taking out the voice synthesis capability from dedicated hardware and implementing it as software on standard devices, the system eliminates complex hardware connections while maintaining the audio information provision function
Solution Approach 2:
The system uses software as an intermediary layer between the telecommunication terminal and the user. Instead of requiring physical hardware intermediaries connected between the telephone set and telecommunication system, the patent employs software mediators that capture terminal status information and convert it to audio through the terminal's existing audio output capabilities, simplifying the overall system architecture
3Ease of operation
If a direct connection is established between the monitor computer and the telecommunication terminal, then audio conversion is enabled, but network security may be compromised
Solution Approach 1:
The patent applies local quality by creating a restricted communication channel between the monitor computer and telecommunication terminal that is isolated from the broader network. The direct connection uses specific protocols and interfaces that allow audio conversion functionality while implementing local security measures that prevent this connection from providing access to other network devices, thus maintaining network security while enabling audio conversion

AI summary
A method and apparatus provide terminal status information by a telecommunication terminal as audio information by generating terminal status information by a telecommunication terminal; establishing a direct connection by a monitor computer to the telecommunication terminal via a direct link to the telecommunication terminal; transmitting the generated terminal status information to the monitor computer by the telecommunication terminal via the direct link; converting the generated terminal status information to audio terminal status information by the monitor computer; and presenting the audio terminal status information to a user of the telecommunication terminal. In addition, the method and apparatus establish a firewall by the telecommunication terminal to prevent the monitor computer from communicating on a network to which the telecommunication terminal is connected whereby the monitor computer is also denied access to other devices connected to the network.
