Solution Overview

Problem

Existing methods for converting voice messages to text messages in mobile radio networks face challenges due to poor speech recognition quality, especially in noisy environments and variable connection quality, making the process complex and costly.

Innovation Solution

A method where the text message generated from a voice message is checked and edited by the sender before transmission, using an editor application or voice dialog system, allowing for voice navigation, acoustic and optical recognition, and dual-tone multi-frequency inputs, and sent via SMS or MMS, eliminating the need for speech recognition supporting services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If speech recognition services with appropriate personnel are used to improve text message quality, then the quality of text messages improves, but the complexity and cost of the system increases

Engineering Contradiction:
Improvetext message qualityVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The sender performs self-checking and self-editing of the text message using an editor application or voice dialog system. The system enables the user to independently verify and correct the converted text without requiring external speech recognition services with personnel, thereby maintaining quality while reducing system complexity and cost.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If speech recognition services with appropriate personnel are used to improve text message quality, then the quality of text messages improves, but the cost of the system increases

Engineering Contradiction:
Improvetext message qualityVSAvoidsystem cost
Core Design Contradiction:
Measurement precisionVSLoss of energy

Solution Approach 1:

The sender independently checks and edits the text message using provided tools (editor application or voice dialog system), eliminating the need for costly external speech recognition services with personnel. This self-service approach maintains acceptable quality while significantly reducing system cost.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If the text message is checked and edited by the sender before transmission, then the quality of text messages improves, but the time required for message transmission increases

Engineering Contradiction:
Improvetext message qualityVSAvoidmessage transmission time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The sender performs partial checking and editing of the text message rather than complete revision. The system provides tools for quick verification and minor corrections, allowing the sender to achieve sufficiently usable results without extensive time investment, balancing quality improvement with time efficiency.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

The method involves creation of text message from the voice message that is audited by the message transmitter before transmitting to a message receiver and edited as required. The transmission is done according to a Global system for mobile communication (GSM), General packet radio service (GPRS)or Universal mobile telecommunications system (UMTS)radio network standard. A short message service (SMS) or a multimedia message service (MMS) is intelligent service. Independent claims are included for the following: (1) a network node in a telecommunications network, particularly a portable radio network in accordance with a global system for mobile communication, a general packet radio service or a universal mobile telecommunications system radio network standard; and (2) a terminal for use in telecommunications network.
