Voice-to-Text Display with Preview Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current voice-to-text conversion technologies are inefficient for speakers who need to convey messages during lectures or announcements, as they require manual writing, which diverts attention and reduces speed and readability.
Innovation Solution
A display device with a storage unit, display unit, sensor unit, and processor that converts voice data to text and allows users to preview and edit the text through touch inputs, enabling easy display of converted text without manual writing, with options for font size and layout adjustments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a speaker writes messages on the blackboard during lecture, then the message can be displayed, but the writing speed is slow and readability is reduced
Solution Approach 1:
The patent replaces the manual mechanical writing system with an automated voice-to-text conversion system. The speaker's voice is captured by a microphone, processed by a processor that converts speech to text, and displayed on the display unit. This substitution eliminates the manual writing process entirely, achieving both high display speed and maintained readability through digital text generation.
2Ease of operation
If a speaker writes on the blackboard simultaneously while speaking, then the message can be conveyed, but the speaker cannot concentrate on the lecture
Solution Approach 1:
The system enables the speaker to perform the writing function through voice commands alone, without manual intervention. The processor automatically captures the voice input, converts it to text, and displays it on the display unit. This self-service mechanism allows the speaker to maintain full concentration on the lecture content while the system handles the message display autonomously.
3Area of stationary object
If the display device size is large, then more text can be displayed, but the writing range becomes unreachable for the user
Solution Approach 1:
The patent replaces manual writing operations with voice-based text generation. Since the text is generated automatically from voice input rather than being manually written, the physical reachability of the display area becomes irrelevant. Users can interact with any portion of the displayed text through voice commands or simple touch inputs, making large displays equally accessible regardless of their physical size.
4Reliability
If manual writing is used to display messages, then the message can be shown, but the speaker's attention is diverted from the lecture
Solution Approach 1:
The voice-to-text conversion system operates autonomously to handle message display, allowing the speaker to maintain uninterrupted focus on lecture delivery. The processor continuously captures voice input and generates corresponding text displays without requiring speaker intervention, ensuring both high lecture delivery quality and sustained speaker concentration.
Data Source
AI summary
A display device for converting a voice to a text and displaying the converted text and a method thereof are disclosed. The display device comprises a storage unit configured to store the voice data; a display unit configured to display the text; a sensor unit configured to detect a user input to the display unit; and a processor configured to convert the voice data to the text and display the converted text in the display unit, wherein the processor provides a text preview interface displaying at least a part of the text in the display unit, in response to a first user input, and provides a text output interface displaying the text in the display unit, in response to a second user input, and the text output interface displays the text in accordance with the second user input.
