Virtual Acoustic Testing for Speech-Enabled Audio Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio device testing for speech-enabled devices is inefficient and costly due to the need for physical re-testing in multiple dedicated audio rooms, causing delays and increased development costs, and is limited by manufacturing tolerances and inconsistent results across different units.
Innovation Solution
A method and system for generating a virtual audio device data package that captures device-specific acoustic characteristics, allowing simulation of multiple test environments without physical shipment, enabling early and broader testing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical re-testing is performed in multiple dedicated audio rooms, then testing accuracy and certification reliability are improved, but testing time and development costs increase significantly
Solution Approach 1:
The patent creates a virtual acoustic environment that copies and simulates multiple physical audio rooms' acoustic characteristics. Instead of physically transporting devices through multiple dedicated audio rooms, the system generates virtual representations of these environments and applies them to test audio devices remotely, maintaining testing accuracy while eliminating the need for physical presence in multiple locations.
Solution Approach 2:
The patent replaces the mechanical system of physical device transportation and physical room-based testing with a digital/virtual system. Virtual acoustic environments are generated and applied remotely, substituting the need for physical audio rooms and device shipping with computational simulations that preserve acoustic testing fidelity.
2Adaptability or versatility
If physical device shipping between OEM and developers is performed, then hardware adjustments and re-testing are enabled, but development time and logistics costs increase
Solution Approach 1:
The patent creates virtual copies of audio devices along with their acoustic characteristics. These virtual device representations can be adjusted and re-tested computationally without requiring physical device shipping. Developers can make hardware adjustments in the virtual model and immediately re-test in simulated environments, eliminating logistics delays.
Solution Approach 2:
The patent introduces a virtual acoustic environment as an intermediary between the physical device and the testing process. This virtual layer allows developers to simulate hardware adjustments and test different configurations without physically modifying or transporting the actual device, serving as a mediator that enables rapid iteration.
3Adaptability or versatility
If multiple dedicated audio rooms are used for testing, then acoustic environment diversity is improved, but device complexity and testing setup requirements increase
Solution Approach 1:
The patent creates a universal virtual acoustic environment system that can represent multiple different physical audio rooms within a single computational framework. Instead of requiring separate physical setups for each acoustic environment, the system generates virtual representations of diverse acoustic spaces that can be applied to the same audio device model, enabling environmental diversity without proportional increases in physical infrastructure complexity.
