Smart Speaker Wake-Up Selection via Timestamp Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When multiple smart speakers coexist, they often respond simultaneously to a wake-up word, leading to chaotic speech interactions and a poor user experience due to multiple devices entering a listening state simultaneously.
Innovation Solution
A method where smart speakers in a wireless network receive and recognize a wake-up word, record timestamps or speech intensities, and compare these values to determine which speaker to wake up first, ensuring only the closest speaker to the user enters a listening state, thereby avoiding simultaneous wake-ups.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple smart speakers respond simultaneously to a wake-up word, then all speakers can be activated, but this causes chaotic speech interaction and noisy environment
Solution Approach 1:
The patent applies local quality by making each smart speaker evaluate its own local conditions (speech intensity, timestamp) to determine whether to wake up. Instead of all speakers responding uniformly, each speaker independently assesses its proximity to the user based on local acoustic measurements and makes a decentralized decision, thereby eliminating chaotic simultaneous responses while maintaining reliable speech interaction.
2Adaptability or versatility
If all smart speakers enter listening state simultaneously, then user coverage is maximized, but speech interaction efficiency deteriorates
Solution Approach 1:
The patent implements preliminary action by having smart speakers pre-evaluate speech intensity and record timestamps before actually entering the listening state. This preliminary assessment allows speakers to predict which one should respond based on proximity metrics, enabling efficient single-speaker selection while still maintaining the capability for multiple speakers to be activated if needed for comprehensive user coverage.
3Measurement precision
If smart speakers use speech intensity comparison to select wake-up candidate, then the closest speaker is selected, but this requires additional recognition processing
Solution Approach 1:
The patent applies self-service by having each smart speaker independently perform speech intensity recognition and timestamp recording on its own, without requiring complex centralized coordination or additional external processing systems. Each speaker uses its built-in microphone and processor to measure local speech intensity, compare it with received intensity data from other speakers, and autonomously determine whether to wake up, thereby achieving precise proximity detection without excessive device complexity.

AI summary
The present disclosure discloses a smart speaker wake-up method, a smart speaker wake-up device, a smart speaker and a storage medium, relates to the technical field of speech recognition. The method of the present disclosure is applied to a wireless network including two or more smart speakers, and a specific implementation thereof is: receiving, speech information including a wake-up word; performing a recognition processing to the speech information to obtain identification information corresponding to the wake-up word; and waking up one smart speaker in the wireless network to enter listening state according to the identification information. The present disclosure may be applied to a scenario where multiple smart speakers coexist, so as to quickly select one smart speaker that is most likely to be wakened, avoiding a chaotic speech interaction caused by multiple smart speakers being wakened simultaneously, improving efficiency and quality of speech interaction and achieving better user experience.
