Electronic Device Wake Word Generation from Pre-Wake Audio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often struggle to accurately wake up electronic devices using pre-configured voice interaction wake words, leading to degraded user experience due to mispronunciation or semantic misunderstandings.
Innovation Solution
An information processing method that collects audio information before waking the device, stores it, and generates alternative wake words based on the input, allowing the device to switch from sleep mode to wake mode more efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-configured wake words are used, then the device can be woken up, but the user experience degrades when users cannot accurately pronounce or remember the wake words
Solution Approach 1:
The system automatically collects audio information from user inputs, stores it, and generates alternative wake words without requiring manual configuration. The device serves itself by learning from user attempts and expanding its wake word vocabulary automatically, eliminating the need for users to precisely memorize wake words
Solution Approach 2:
The system collects audio information from user inputs (even failed attempts), stores this feedback data, and uses it to generate improved alternative wake words. This feedback loop continuously enhances the wake-up function by learning from actual user pronunciation patterns and semantic preferences
2Adaptability or versatility
If multiple alternative wake words are generated, then the device becomes more adaptable to different user pronunciations, but the device complexity increases
Solution Approach 1:
The system extracts only the essential audio information from user inputs and stores it separately for processing. By extracting and storing only the necessary wake word data rather than processing all audio continuously, the system achieves high adaptability while maintaining relatively simple device architecture
Solution Approach 2:
The system performs preliminary actions by collecting and storing audio information during idle periods before wake-up events occur. This preliminary data collection and storage enables the generation of multiple alternative wake words in advance, reducing the complexity of real-time processing during actual wake-up scenarios
Data Source
AI summary
An information processing method and an electronic device are provided. The method is applied to an electronic device and comprises collecting audio information received by the electronic device before waking up the electronic device; storing the audio information; and based on the stored audio information, generating alternative wake words. The wake words facilitate the electronic device to switch from a sleep mode to a wake mode.
