Voice Control Interface With Segmented Processing Modules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice recognition systems in mobile devices require waking the main processor to provide visual notifications during sleep mode, consuming power and resources, and do not allow for progressive command engagement without fully activating the device.
Innovation Solution
Implementing a voice control user interface that decomposes voice command phrases into segments, allowing for user interactions during low-power states, with a secondary processor managing control operations and waking the main processor only when necessary, enabling partial display updates and audible responses without fully activating the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the main processor is kept awake to provide visual notifications and full voice command processing, then user interaction capability and notification visibility are improved, but power consumption increases
Solution Approach 1:
The patent segments voice command processing into multiple stages: initial keyword detection by a low-power module, followed by selective activation of the main processor for full command processing. This segmentation allows the system to maintain basic interaction capabilities with minimal power consumption while preserving full functionality when needed.
Solution Approach 2:
The patent implements partial action by allowing the device to remain in sleep mode for basic operations while selectively activating full processing power only when necessary. The display can show simplified notifications without fully waking the processor, and voice commands are initially processed by a low-power module before escalating to full processing only when required.
2Loss of information
If the display is fully activated to show visual notifications, then notification visibility and information display are improved, but power consumption and device wake-up requirements increase
Solution Approach 1:
The patent applies local quality by enabling the display to show simplified or partial visual notifications without activating the entire display system or main processor. Certain display regions or notification types can be rendered with reduced power consumption while maintaining essential information visibility.
Solution Approach 2:
The system performs partial display activation where only necessary visual elements are rendered without fully waking the display controller or main processor. This allows critical notification information to be displayed while consuming minimal power and maintaining sleep mode for the majority of system components.
3Use of energy by moving object
If voice command phrases are processed in segments with progressive command engagement, then power efficiency is improved, but system complexity increases
Solution Approach 1:
The patent segments voice command processing into distinct stages with different power requirements. A low-power module handles initial keyword detection and simple commands, while the main processor handles complex commands only when activated. This segmentation reduces average power consumption while managing complexity through modular architecture.
Solution Approach 2:
The patent introduces an intermediary low-power processing module that sits between the microphone input and the main processor. This intermediary module filters and pre-processes voice inputs, determining whether full processor activation is necessary, thereby reducing overall system complexity while maintaining power efficiency.

AI summary
A method include placing a first processor in a sleep operating mode and running a second processor that is operative to wake the first processor from the sleep operating mode in response to a speech command phrase. The method includes identifying, by the second processor, a speech command phrase segment and performing a control operation in response to detecting the segment in detected speech. The control operation is performed while the first processor is maintained in the sleep operating mode.
