Voice Input Controller for Mobile Text Entry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices with touch panels for character input can be cumbersome for users, as they require manual contact operations to input characters, which may be troublesome, especially for users seeking to input text efficiently.
Innovation Solution
An electronic device equipped with a voice input unit, a display, and a controller that accepts voice inputs and converts them into text within a text input field or software keyboard, allowing users to input characters vocally instead of manually.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual touch panel operations are used for character input, then text input can be achieved, but the operation becomes cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical touch panel input system with a voice recognition system. The voice input unit captures spoken characters, the recognition unit converts speech to text, and the registration unit inputs the recognized text. This substitution eliminates the need for manual touch operations, directly resolving the contradiction by improving text input efficiency while reducing character input effort.
2Productivity
If voice input is implemented, then text input efficiency is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into existing mobile phone components. The voice input unit uses the existing microphone, the recognition unit leverages standard speech recognition algorithms, and the registration unit utilizes the existing character registration functionality. By making these components multi-functional, the patent improves text input efficiency while minimizing the increase in device complexity.
3Extent of automation
If voice recognition is added to the system, then automated text input is achieved, but the system becomes more complex
Solution Approach 1:
The patent implements a self-service mechanism where the voice recognition system automatically processes spoken input without requiring manual intervention. The recognition unit continuously monitors the voice input unit, automatically recognizes characters, and the registration unit automatically inputs the recognized text into the display. This automation reduces the need for complex control systems while achieving high程度的 automated text input.

AI summary
An electronic device includes a microphone; a display; a touch panel; and a controller. The controller is configured to start accepting, through the microphone, a specific voice command input. The controller is configured to start accepting voice input in response to a text input field being displayed on the display, wherein the accepting voice input includes converting voice inputted through the microphone into text, and inputting the converted text into the text input field. During the accepting voice input, when a predetermined word corresponding to a specific voice command is recognized, the controller is configured to determine whether voice is inputted through the microphone during two intervals of a predetermined duration before and after the predetermined word, respectively.
