Using Ruby to Enhance Accessibility Features for IoT Devices - Specific Approach Needed
I've been researching this but I'm working on a project and hit a roadblock... This might be a silly question, but Recently started working on a project aimed at improving accessibility features in IoT devices using Ruby on Rails. My goal is to implement voice commands for users with limited mobility, and I’m trying to leverage the `speechrecognition` gem for this purpose. While experimenting, I’ve set up a basic Rails application that listens for voice input and processes commands. The initial code looks something like this: ```ruby class VoiceController < ApplicationController def listen @speech_input = SpeechRecognition.new if @speech_input.recognize process_command(@speech_input.result) else render json: { error: 'No input detected' }, status: :unprocessable_entity end end private def process_command(command) case command.downcase when 'turn on the light' # Code to turn on light when 'play music' # Code to play music else render json: { message: 'Command not understood' } end end end ``` The `speechrecognition` gem works well in a controlled environment, but I'm running into complications when trying to implement this on actual devices. Specifically, the recognition accuracy drops significantly in noisy environments, which is a common scenario for IoT devices interacting in real-world settings. I read that implementing a noise-cancellation approach could improve performance, but I’m not sure how to integrate this effectively within my Rails app. I’ve also skimmed through examples that suggest using WebSockets for real-time communication, which sounds promising, but I’m not clear on how to set it up with the current architecture. Here’s what I’ve tried so far: 1. Adjusted microphone settings on the device to pick up clearer sounds, but results were inconsistent. 2. Introduced a noise filter using some basic audio processing techniques, yet the implementation in Ruby was not straightforward, and performance suffered. 3. Explored alternatives like using a JavaScript front-end to handle the audio input and send commands via API, but I want to keep it all Ruby-centric if possible. Is there a recommended architecture or approach that could enhance the speech recognition capability in this context? Any specific libraries or patterns I should consider for handling noisy audio input directly in Ruby on Rails? For context: I'm using Ruby on Linux. For context: I'm using Ruby on Windows. Thanks in advance! I'd really appreciate any guidance on this.
