Voice Interactive Device Trigger Word Service Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice interactive systems lack the ability to seamlessly switch between multiple voice interactive services based on unique trigger words, limiting user flexibility and efficiency in requesting specific services.
Innovation Solution
A voice interactive device equipped with a keyword detector and controller that identifies and responds to different trigger words by transmitting voice content to corresponding voice interactive services, allowing users to switch services by speaking specific keywords, thereby enhancing user interaction and service utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a voice interactive device supports multiple voice interactive services, then service versatility is improved, but service selection complexity increases and requires manual intervention
Solution Approach 1:
The system automatically switches between voice interactive services based on trigger word recognition without requiring manual user intervention. The controller detects trigger words in the voice content and autonomously determines which service to activate, making the service selection process self-service oriented and eliminating complex manual operations.
Solution Approach 2:
Trigger words serve as intermediaries between the user's voice input and the voice interactive services. Instead of directly selecting services, users speak trigger words that the controller recognizes and translates into appropriate service activation, simplifying the interaction interface while maintaining access to multiple services.
2Productivity
If trigger word recognition is implemented for service switching, then service selection efficiency is improved, but keyword detection complexity increases
Solution Approach 1:
The keyword detection function is extracted as a separate module (keyword detector) within the voice interactive device. This dedicated component focuses specifically on detecting trigger words in voice content, separating this complex task from the overall service management system and enabling specialized optimization of the detection process.
Solution Approach 2:
The system performs preliminary trigger word detection on voice content before routing to specific services. By pre-processing the voice input to identify trigger words and determine the appropriate service in advance, the system streamlines the overall processing flow and improves service selection efficiency without adding complexity to the service execution phase.
