Mobile Terminal Voice Text Conversion During Calls
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Rich Communication Suite enhanced (RCSe) technologies cannot provide speech recognition features such as Text To Speech (TTS) and Speech To Text (STT) during voice communications, limiting the ability to search and send information like documents, phone books, images, and music without manual intervention.
Innovation Solution
A method and mobile communication terminal configuration that includes a voice-text conversion unit to convert voice signals into text during a call, allowing for the identification and transmission of matching information from the terminal's memory to another party, using TTS and STT technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If speech recognition technology (TTS/STT) is integrated into existing RCSe during voice communication, then the ability to search and send information is improved, but the device complexity increases
Solution Approach 1:
The patent merges speech recognition technology (both TTS and STT) with the existing RCSe communication service, integrating multiple functions into a unified system that allows voice-based information searching during calls without requiring separate applications
Solution Approach 2:
The RCSe system is enhanced to perform multiple functions simultaneously: voice communication, speech-to-text conversion, text-to-speech conversion, and information searching, making the system universally applicable for both communication and information retrieval tasks
2Productivity
If manual intervention is required to search and send information during calls, then the ease of operation is maintained, but the productivity decreases
Solution Approach 1:
The system enables self-service information searching by automatically converting spoken search queries into text and executing the search without requiring manual typing or navigation, allowing users to efficiently search and share information through natural voice commands during calls
3Adaptability or versatility
If speech recognition technology is added to provide TTS and STT capabilities, then the functionality is improved, but the loss of information increases due to processing delays
Solution Approach 1:
The system performs preliminary actions by continuously monitoring and processing voice signals during calls, converting speech to text in real-time, and preparing search results before the user needs them, thereby minimizing information delivery delays
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to guide data communication states and share various information stored in the memory with the other party during a call, enhancing the communication experience by integrating speech recognition capabilities without the need for separate applications.
Implementation Method 1
a voice-text conversion unit for converting the digital voice signal received from the voice codec unit into text
Implementation Method 2
a voice codec unit for converting an analog voice signal received from a microphone into a digital voice signal
Data Source
AI summary
A method of providing information of a mobile communication terminal, and a mobile communication terminal for performing the method, are provided. The method includes determining whether a search command event has been generated during a call with a counterpart terminal, converting a voice signal received from a microphone into a text when the generation of search command event is determined to have been generated, identifying information matching the text in a memory, and sending the information to the counterpart terminal.
