Voice Data Clause Segmentation for Packet Loss Resilience
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice data transmission over IP networks, such as the Internet, faces challenges in maintaining voice quality due to packet loss and communication path deterioration, leading to interruptions and failure in recognizing speech, especially in non-guaranteed Quality of Service (QoS) environments.
Innovation Solution
A voice data transmitting and receiving system that divides voice data into clause units for transmission and reassembles them on the receiving end, using real-time communication packets (RTPs) to ensure reliable data transfer and interpolation processes to handle packet loss, allowing for continuous and intelligible voice communication even in deteriorated environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If RTP packets are used for voice data transmission to ensure real-time communication, then communication speed is improved, but packet loss occurs on communication paths leading to voice quality deterioration
Solution Approach 1:
The patent segments voice data into smaller clause units before packetization. This segmentation allows for more granular control over data transmission, enabling selective retransmission of only the lost clause units rather than entire packets, thereby maintaining real-time communication speed while improving voice quality reliability.
Solution Approach 2:
The patent performs preliminary actions by dividing voice data into clause units and preparing them for selective retransmission before actual transmission occurs. This preliminary organization of data allows the receiving end to quickly reconstruct voice data even when some packets are lost, maintaining communication speed without sacrificing voice quality.
2Adaptability or versatility
If packet loss occurs in deteriorated communication environments, then communication adaptability is improved, but speech meaning recognition fails
Solution Approach 1:
By segmenting voice data into clause units, the patent enables selective retransmission of only the lost segments. This allows the communication system to adapt to packet loss conditions while preserving the integrity of speech meaning, as only the necessary portions are retransmitted and the overall speech structure remains intact.
Solution Approach 2:
The patent implements feedback mechanisms where the receiving end detects packet loss and requests retransmission of specific clause units. This feedback loop allows the system to adapt to communication conditions dynamically while ensuring that speech meaning is preserved through targeted retransmission of only the lost information.
3Productivity
If voice data is transmitted as continuous packets, then transmission efficiency is improved, but packet loss causes interruptions in voice output
Solution Approach 1:
The patent segments continuous voice data into discrete clause units, which are then transmitted as packets. This segmentation allows for more flexible handling of packet loss, as individual clause units can be retransmitted without interrupting the overall voice stream, thereby maintaining both transmission efficiency and voice continuity.
Solution Approach 2:
The patent performs preliminary division of voice data into clause units before transmission. This preliminary action enables the system to maintain transmission efficiency by sending data in optimized units while also preparing for continuous voice output by ensuring that lost units can be quickly reconstructed without breaking voice continuity.

AI summary
Voice clauses are divided and transmitted as packet data in divided clause units in a transmission side. The voice data is outputted as voice based on the received packet data in clause units in a receipt side. Thus, the meaning of speech is even able to be recognized in a deteriorated communication path environment.
