Voice Input Apparatus Dynamic Period Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice input apparatuses face issues with operability due to fixed or improperly set voice operation periods, leading to reduced user experience and potential erroneous operations, as they do not adapt effectively to the nature of voice instructions.
Innovation Solution
A voice input apparatus that adjusts the length of the voice operation period based on the first voice instruction input, allowing for dynamic setting of voice reception periods according to the type or context of the voice instruction, thereby enhancing operability and reducing unintended voice recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a fixed predetermined period is used for voice operations, then the apparatus can respond to voice commands, but the operability is reduced when the period is too short for tasks requiring reading time, and unintended voice operations occur when the period is too long
Solution Approach 1:
The voice operation period is changed from a fixed value to a dynamic value that automatically adjusts based on the type of voice instruction received. The control unit determines the appropriate period length according to the instruction content, allowing the system to adapt to different operational contexts and reduce both operability reduction and erroneous operations.
Solution Approach 2:
The duration parameter of the voice operation period is modified based on the voice instruction type. The control unit changes the period length as a variable parameter according to the determined instruction category, enabling optimal operation timing for different tasks such as text reading versus quick setting changes.
2Ease of operation
If the voice operation period is extended to allow sufficient reading time for text display, then operability improves for page navigation tasks, but unintended voice commands are more likely to be recognized
Solution Approach 1:
The system dynamically adjusts the voice operation period based on the specific task type. For page navigation tasks requiring reading time, a longer period is applied, while for quick setting changes, a shorter period is used. This dynamic adjustment minimizes the window for unintended voice commands while ensuring sufficient time for user interaction.
Solution Approach 2:
The voice operation period parameter is changed according to the voice instruction type. The control unit selects appropriate period lengths from different ranges based on the determined instruction category, optimizing the balance between providing sufficient reading time and limiting exposure to unintended voice commands.
3Reliability
If the voice operation period is shortened to prevent unintended voice operations, then reliability improves, but the operability is reduced for tasks requiring continuous or reflective processing
Solution Approach 1:
The voice operation period is dynamically determined based on the voice instruction type received. The control unit selects appropriate period lengths according to the instruction content, allowing shorter periods for simple tasks to prevent erroneous operations while extending periods for reflective tasks like text reading to maintain operability.
Solution Approach 2:
The duration parameter is changed based on the voice instruction category. The control unit modifies the voice operation period as a variable parameter, selecting from different time ranges appropriate for the specific task type, thereby optimizing both reliability and operability simultaneously.

AI summary
A voice input apparatus includes a voice input device configured to input voice and performs control to, in a case where a second voice instruction for operating the voice input apparatus is input in a predetermined period after a first voice instruction is input to the voice input apparatus, execute processing corresponding to the second voice instruction. The voice input apparatus changes a length of the predetermined period, according to the first voice instruction.
