Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Voice recognition technologies are limited by the physical range of microphones, restricting the spatial extent of voice recognition and requiring multiple microphones to expand this range, which can lead to incomplete service capabilities across different devices.
Innovation Solution
A voice recognition apparatus and method that utilizes a network of interconnected voice recognition devices via IoT, allowing a single device to communicate with external apparatuses to determine wake-up words and request services, thereby expanding the recognition range and enabling more versatile service provision across various domains.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If multiple microphones are used to expand recognition distance, then the recognition range is improved, but the device complexity increases
Solution Approach 1:
The patent transitions from expanding recognition range within a single device to achieving it across multiple spatially distributed devices. By deploying voice recognition apparatuses at different locations (living room, bedroom, etc.), the system achieves extended recognition range without increasing the microphone count within any single device, thus avoiding the complexity trade-off.
Solution Approach 2:
The patent makes each voice recognition apparatus capable of providing multiple services beyond just voice recognition. Each apparatus can function as a standalone voice recognition device or collaborate with other apparatuses to provide enhanced services, allowing a single device to perform multiple functions and reducing the need for additional specialized components.
2Adaptability or versatility
If each voice recognition apparatus provides unique services, then service versatility is improved, but the overall service coverage is limited
Solution Approach 1:
The patent combines the service capabilities of multiple voice recognition apparatuses into a unified service ecosystem. When a user activates an apparatus, the system merges the functionality of that apparatus with other apparatuses in the network, allowing services from different devices to be integrated and provided together, thus expanding overall service coverage while maintaining service variety.
Solution Approach 2:
The patent introduces a server as an intermediary that coordinates communication between voice recognition apparatuses and users. The server manages service routing, coordinates collaborations between apparatuses, and ensures that services are appropriately distributed across different devices, enabling comprehensive service coverage while preserving the unique capabilities of each apparatus.
3Area of stationary object
If voice recognition apparatuses are deployed in multiple locations, then spatial coverage is improved, but the difficulty of coordinating services increases
Solution Approach 1:
The patent employs a server as a central coordinator that simplifies the management of multiple distributed apparatuses. The server handles service routing decisions, coordinates communication protocols between apparatuses, and manages the overall system state, thereby reducing the coordination complexity that would otherwise arise from direct peer-to-peer communication between multiple locations.
Solution Approach 2:
The patent divides the voice recognition system into independent modular apparatuses, each capable of autonomous operation. Each apparatus independently handles local voice recognition tasks and only communicates with the server for service coordination, which segments the complexity and allows each component to operate simply while the system as a whole achieves coordinated functionality across multiple locations.

AI summary
Disclosed is a voice recognition apparatus connected via a network and sharing a voice recognition function. The voice recognition apparatus includes: a microphone configured to receive a voice signal from a user's speech; a communicator configured to communicate with at least one external voice recognition apparatus; a voice recognizer configured to determine a wake-up word involved in the voice signal; and a controller configured to transmit the voice signal to the external voice recognition apparatus corresponding to the determined wake-up word. Thus, it is possible to overcome a limited voice recognition distance caused by a physical characteristic of a microphone and expand a spatial range where voice recognition is possible, thereby providing various voice recognition services to a user in more places.
