Wireless Speech Barrier Operator Noise Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing barrier operator systems often receive poor-quality voice transmissions due to noise, leading to incorrect command recognition or failure to recognize commands, which affects the proper actuation of moveable barriers.
Innovation Solution
A wireless speech transmission device communicates high-quality, noise-free speech data using a low-power personal area network, allowing a moveable barrier operator to intercept and recognize speech patterns, thereby actuating the barrier accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireless transmission devices are used for barrier operator systems, then the system can receive voice transmissions, but the quality of the voice transmission is frequently inadequate due to large amounts of noise
Solution Approach 1:
The patent introduces an intermediary device (such as a smartphone or audio recording device) that captures the voice command in a quiet environment and then transmits it to the barrier operator. This intermediary acts as a mediator between the user and the barrier operator, filtering out noise and delivering a clean audio signal for accurate recognition.
Solution Approach 2:
The patent replaces the traditional direct wireless transmission system with a digital audio processing system. Instead of relying on noisy direct transmission, the system uses digital audio files or recorded messages that can be processed and filtered to remove noise, substituting the mechanical/acoustic transmission path with a digital processing path.
2Measurement precision
If the barrier operator uses traditional voice transmission systems, then it can receive commands, but it frequently fails to properly determine the message due to poor transmission quality
Solution Approach 1:
The patent applies preliminary action by having the user record or prepare the voice command in advance in a quiet environment using a high-quality recording device. The audio is captured and processed before transmission, ensuring that the speech pattern is clear and free from the noise that would interfere with recognition at the barrier operator.
Solution Approach 2:
The patent uses copying by creating a digital copy of the voice command in a controlled environment. Instead of transmitting live voice that may be noisy, the system captures a clean copy of the command and transmits this copied audio signal, which can be played back multiple times with consistent high quality.
Data Source
AI summary
A system includes a wireless speech transmission device that communicates a wireless transmission of speech representing data in a first protocol via a wireless network. The speech representing data conveys substantially noise-free human speech. A wireless speech communication device receives the speech representing data in the first protocol via the network and couples representations of the data to a speech communication apparatus in a second protocol. A moveable barrier operator is within receiving range of the wireless transmission of the data from the wireless speech transmission device, intercepts the wireless transmission from the wireless speech transmission device, and recognizes a speech pattern from the data in the wireless transmission. A barrier movement apparatus actuates the barrier based upon the speech pattern.
