Wearable Earphone Voice Pickup for Cloud AI Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Echo Dot devices have poor sound pickup capabilities, especially in noisy environments, and require users to be close for effective voice command recognition, leading to inconvenient user experiences.
Innovation Solution
A portable AI voice interaction system comprising an earphone that converts user voice to digital signals via analog-to-digital conversion and transmits them wirelessly to a body device, which sends them to a cloud server for voice recognition and semantic analysis, allowing for accurate command processing and voice broadcasting without the need for high data processing capabilities in the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Echo Dot uses a built-in microphone array, then the device can recognize voice commands, but the sound pickup capability deteriorates in noisy environments and at distances
Solution Approach 1:
The patent extracts the voice pickup function from the Echo Dot device itself and relocates it to a separate wearable device (earphone or collar microphone). This allows the main device to focus on processing while the wearable component handles sound acquisition close to the user's mouth, effectively removing the limitation of the built-in microphone array's poor pickup capability.
Solution Approach 2:
The patent introduces a wearable intermediary device (earphone or collar microphone) that acts as a mediator between the user's voice and the Echo Dot processing system. This intermediary captures voice signals directly near the user's mouth, providing clear audio input to the processing device while being isolated from environmental noise.
2Speed
If Echo Dot processes voice data locally, then the device can respond quickly, but the device complexity and data processing capability requirements increase
Solution Approach 1:
The patent segments the voice processing system into two parts: a simple wearable device for voice capture and transmission, and a cloud-based processing system for comprehensive analysis. This segmentation allows complex processing to occur in the cloud while keeping the local device simple and responsive.
Solution Approach 2:
The patent introduces a cloud-based processing intermediary that handles the complex voice recognition and command interpretation tasks. This allows the local Echo Dot device to remain relatively simple while still achieving accurate and comprehensive voice command processing through the cloud intermediary.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides improved sound pickup and accurate voice recognition, enhancing user experience by allowing voice commands to be recognized from a distance and in noisy conditions, while reducing device costs through cloud-based processing.
