Relay Apparatus User-Specific Dictionary Selection for Voice Conversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems fail to perform optimum communication control based on user characteristics and statuses, leading to suboptimal conversion accuracy between voice and text data.
Innovation Solution
A relay apparatus that stores and selects characteristic information for each communication terminal, using this information to choose appropriate dictionary data for converting voice to text and text to voice, enhancing conversion accuracy by tailoring the process to user-specific characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single dictionary information is used for all users, then the device complexity is reduced, but the conversion accuracy from voice to text or text to voice deteriorates
Solution Approach 1:
The patent segments the single dictionary information into multiple user-specific dictionary informations, each tailored to individual user characteristics. The relay apparatus stores multiple pieces of dictionary information corresponding to different users, and selectively provides the appropriate dictionary information based on user identification, thereby improving conversion accuracy without requiring each terminal device to store all dictionary informations locally.
Solution Approach 2:
The relay apparatus acts as an intermediary between communication terminals and dictionary information. Instead of each terminal device managing multiple dictionary informations locally, the relay apparatus stores and manages multiple user-specific dictionary informations, selecting and providing the appropriate one during communication. This mediator approach improves conversion accuracy while reducing the complexity burden on individual terminal devices.
2Measurement precision
If multiple dictionary informations are stored in each communication terminal, then the conversion accuracy is improved, but the memory requirements and processing overhead increase
Solution Approach 1:
The patent merges the storage function of multiple dictionary informations into a centralized relay apparatus rather than distributing them across multiple communication terminals. The relay apparatus consolidates multiple user-specific dictionary informations in one location, allowing terminal devices to access only the necessary dictionary information during communication, thereby reducing total memory requirements while maintaining high conversion accuracy.
Solution Approach 2:
The relay apparatus provides universal access to multiple user-specific dictionary informations for various communication terminals. Instead of each terminal device independently storing and managing multiple dictionary informations, the relay apparatus serves multiple terminals with different user profiles, reducing redundant storage across the system while enabling accurate conversions for each user.
3Measurement precision
If user-specific dictionary information is selected and provided by a relay apparatus, then the conversion accuracy is improved, but the communication control complexity increases
Solution Approach 1:
The patent extracts the complexity of managing multiple user-specific dictionary informations from communication terminals and places it in the relay apparatus. The relay apparatus handles the complex tasks of storing, selecting, and providing appropriate dictionary information based on user identification, while terminal devices are relieved of this complexity burden. This extraction improves conversion accuracy without significantly increasing the complexity burden on terminal devices.

AI summary
A relay apparatus includes a characteristic information storage unit, a first dictionary information storage unit, a first selection unit, and a first conversion unit. The characteristic information storage unit stores pieces of terminal information in association with respective pieces of characteristic information, each indicating a characteristic of a user. The first dictionary information storage unit stores the pieces of characteristic information in association with respective pieces of first dictionary information used for converting voice data into text data. The first selection unit selects, when voice data is received from a second communication terminal to communicate with a first communication terminal, the characteristic information associated with the terminal information for identifying the second communication terminal and selects the first dictionary information associated with the selected characteristic information. The first conversion unit converts the voice data received from the second communication terminal to text data using the first dictionary information.
