Group Voice-to-Text Messaging for Accurate PTT Communications
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Push-to-Talk (PTT) communication systems, there is a challenge in ensuring accurate information transmission due to miscommunication issues, particularly in systems that rely on one-to-many simultaneous group voice communications, where receivers may not correctly hear intended voice data.
Innovation Solution
A signal processing apparatus assigns a transmission right to one communication terminal in a group, allowing it to transmit voice data, which is then converted into text data and transmitted to other terminals, along with completion notices to manage and correct the display of text data across the group.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If voice data is transmitted in one-to-many group communications, then communication efficiency is improved, but miscommunication occurs due to receivers not hearing intended contents correctly
Solution Approach 1:
The patent introduces a server as an intermediary that receives voice data from the transmitting terminal, converts it to text data, and then distributes the text data to all group members. This intermediary processing ensures that all receivers get the same accurate information regardless of voice transmission quality, resolving the contradiction between communication efficiency and information accuracy.
Solution Approach 2:
The patent replaces the acoustic/mechanical voice transmission system with a text-based data transmission system. By converting voice data to text data on the server side, the system substitutes unreliable voice hearing with reliable text display, ensuring all group members receive identical information accurately while maintaining one-to-many communication efficiency.
2Reliability
If text data is generated and transmitted after voice data, then information accuracy is improved, but communication time increases
Solution Approach 1:
The server performs voice-to-text conversion in the background immediately upon receiving voice data, before notifying group members. This preliminary processing allows the text data to be ready for immediate transmission, minimizing the perceived delay for users while ensuring accurate information delivery.
Solution Approach 2:
The system maintains continuous operation by having the server process voice data conversion and text data transmission in an uninterrupted sequence. The server continuously receives voice data, converts it to text, and distributes the text data without idle periods, reducing overall communication time while maintaining information accuracy.

AI summary
According to one embodiment, a signal processing apparatus correlates a plurality of communication terminals as a group and enables one-to-many communications in the group. The signal processing apparatus includes processing circuitry. The processing circuitry assigns a transmission right to one of the communication terminals in the group. The processing circuitry generates text data based on voice data from said one of the communication terminals in possession of the transmission right. The processing circuitry gives a texting completion notice indicative of completion of texting processing to the communication terminals in the group. The processing circuitry transmits, after the texting completion notice is given, the generated text data to at least one of the communication terminals in the group.
