Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital voice calls consume significant bandwidth, impacting available resources for other applications and potentially degrading consumer experience, and existing methods for real-time voice communication are unreliable due to reliance on internet quality, leading to delays and poor quality.
Innovation Solution
A method for real-time voice communication over a telecommunication network with both voice and data channels, converting voice input to text data at the originating device and back to voice at the receiving device, using user profiles to replicate the original speaker's voice, and monitoring quality to switch between channels based on latency and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital voice calls are used to enable real-time voice communication over internet, then voice communication functionality is improved and cost is reduced, but bandwidth consumption increases significantly
Solution Approach 1:
The patent converts voice signals to text transcripts and transmits the text instead of the original voice data. The receiving device then converts the text back to speech using text-to-speech synthesis. This copying approach transmits a simplified representation (text) rather than the full voice signal, significantly reducing bandwidth consumption while maintaining communication functionality.
Solution Approach 2:
The patent changes the parameter of data representation from audio format to text format. By converting voice to text and back, the system transforms the physical state of the transmitted data, allowing for more efficient bandwidth utilization while preserving the essential communication function.
2Ease of operation
If voice data is transmitted over data channel using internet protocol, then digital voice call functionality is enabled, but communication delay increases when internet connection quality is poor
Solution Approach 1:
The patent creates a text copy of the voice input and transmits this copy over the data channel. Text data requires less bandwidth and can be transmitted more efficiently than voice data, reducing the time required for transmission especially over poor internet connections.
Solution Approach 2:
The patent replaces the traditional voice-over-IP mechanical system with a text-based transmission system. By substituting voice data transmission with text data transmission followed by text-to-speech conversion, the system achieves more reliable and faster transmission over data channels.
3Loss of energy
If speech to text and text to speech conversion is performed to reduce bandwidth usage, then bandwidth consumption is reduced, but device complexity increases
Solution Approach 1:
The patent leverages existing universal speech-to-text and text-to-speech conversion technologies that can be implemented in modern devices. By utilizing these multi-functional capabilities already present in smartphones and computing devices, the system adds text conversion functionality without significantly increasing overall device complexity.
Solution Approach 2:
The patent introduces text data as an intermediary between the sender's voice and the receiver's speech output. This intermediary form requires processing but uses standard conversion technologies, managing the complexity through established methods rather than requiring entirely new processing systems.
4Loss of energy
If text data is transmitted instead of voice data, then bandwidth usage is reduced, but transmission reliability depends on data channel quality
Solution Approach 1:
The patent transmits a text copy of the voice input, which is more resilient to data channel errors than voice data. Text data can be more easily error-corrected and retransmitted if needed, improving reliability while maintaining bandwidth efficiency.
Solution Approach 2:
The system monitors the quality of the generated speech output and can adapt to network conditions. By implementing feedback mechanisms, the system can detect transmission issues and take corrective actions to maintain reliability even when using text-based transmission over data channels.
