Dynamic Voice Trigger Phrase Selection for Context-Aware Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-operated electronic computing devices face challenges in selecting optimal trigger phrases for different contexts, such as ambient noise levels and proximity to specific individuals, which can affect the reliability of voice command detection.
Innovation Solution
The device manages multiple voice operation trigger phrases and dynamically selects the most suitable one based on context, using GPS, microphone, and camera inputs to determine location, noise levels, and proximity, ensuring effective voice operation in various environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single trigger phrase is used for voice operation, then the device complexity is low, but the reliability of voice command detection deteriorates in different contexts
Solution Approach 1:
The system dynamically switches between different trigger phrases based on the detected context (ambient noise levels, location, nearby people). The trigger phrase that is currently loaded is determined by the context, allowing the system to adapt to changing environmental conditions and maintain high detection reliability without requiring a fixed complex structure
Solution Approach 2:
The system changes the parameter of the trigger phrase (different phrases for different contexts) based on environmental parameters such as noise level, location, and social context. This allows optimization of voice command detection for each specific situation without permanently increasing system complexity
2Adaptability or versatility
If multiple trigger phrases are loaded for different contexts, then the adaptability to various environments is improved, but the device complexity increases
Solution Approach 1:
Multiple trigger phrases are pre-loaded into the device's memory during manufacturing or initial setup. The system then automatically selects and loads the appropriate pre-prepared trigger phrase based on the current context, eliminating the need for complex real-time processing or user configuration while maintaining high adaptability
Solution Approach 2:
The trigger phrase management system serves multiple functions: it stores multiple phrases, detects contextual parameters (noise, location, people), selects the appropriate phrase, and loads it for use. This multi-functional approach consolidates complexity into a single universal system rather than requiring separate mechanisms for each function
3Ease of operation
If context-based trigger phrase selection is implemented, then the usability in diverse situations is improved, but the loss of time for context determination increases
Solution Approach 1:
The device autonomously determines the current context by using its own sensors (microphone for noise level, GPS for location, camera or sensors for nearby people) without requiring external input or user intervention. The system self-evaluates environmental parameters and automatically selects the appropriate trigger phrase, minimizing time loss while improving usability

AI summary
A method and apparatus for managing multiple voice operation trigger phrases includes an electronic computing device enabling a first voice operation trigger phrase and a second voice operation trigger phrase on the electronic computing device. The method further includes determining whether a context applies to the electronic computing device, loading the first voice operation trigger phrase upon determining that a first context applies to the electronic computing device, and loading the second voice operation trigger phrase upon determining that a second context applies to the electronic computing device.
