Solution Overview

Problem

In Push-to-Talk (PTT) communication systems, there is a common issue of miscommunication due to receivers not correctly hearing intended voice data, leading to a demand for technology that can suppress such information miscommunication.

Innovation Solution

A communication system and signal processing apparatus that utilize a processing server and communication terminals to convert voice data into text data, allowing for accurate transmission and display of voice communications, with features like texting processing, translation, and correction to ensure clear information delivery across multiple devices.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If voice data is transmitted directly in PTT communication, then communication speed is maintained, but miscommunication occurs due to receivers not hearing intended contents correctly

Engineering Contradiction:
Improvecommunication accuracyVSAvoidinformation miscommunication
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces text data as an intermediary representation of voice data. The text data serves as a mediator that conveys the intended meaning of voice communications more reliably, especially when voice transmission quality is poor or when language barriers exist. This intermediary form reduces information loss and miscommunication.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms voice data into text data, changing the parameter of information representation from acoustic signals to textual form. This parameter change enables better preservation of information content, allows for translation across languages, and provides a more reliable communication channel that reduces miscommunication.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If voice data is converted to text data for accurate transmission, then information accuracy is improved, but system complexity increases due to additional processing requirements

Engineering Contradiction:
Improveinformation accuracyVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements a communication system where the text data generation and translation functions serve multiple purposes: they improve communication accuracy, enable cross-language communication, and provide a record of communications. This multi-functionality justifies the added complexity by delivering multiple benefits from the same processing infrastructure.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If text data translation is added to support multi-language communication, then adaptability is improved, but processing time increases

Engineering Contradiction:
Improvemulti-language supportVSAvoidprocessing time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent performs text data generation and translation in advance during the communication process, rather than on-demand. By preparing translated text data beforehand, the system reduces latency when translated communications need to be delivered, thus mitigating the time loss associated with real-time translation processing.

Inventive Principle:
Principle #10Preliminary action

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 a transmission right assigning unit, a texting processing unit, and a communication controlling unit. The transmission right assigning unit assigns a transmission right to one of the communication terminals in the group. The texting processing unit generates text data based on voice data from said one of the communication terminals in possession of the transmission right. The texting processing unit gives a texting completion notice indicative of completion of texting processing to the communication terminals in the group. The communication controlling unit transmits, after the texting completion notice is given, the generated text data to at least one of the communication terminals in the group.
