vSpeak | VS Code Extension that Offers Voice-based Commands

I built an extension for VS Code (Visual Studio Code) that enables a mouse-free and seamless coding experience by allowing the user to give voice commands for various tasks. It uses Google's Text to Speech API to parse speech from the microphone. An interpreter with built-in Python runs continuously in the background to send the detected commands to the extension's listener. The extension uses native VS Code APIs to execute the commands.

It has helpful speech commands such as debugging, searches on Google, Git tasks, and many others that are supported to make the user's experience seamless.

React Webpack 4 Boilerplate Code

I created React Redux boilerplate code with Webpack and Babel to assist developers with an early head start for new projects. I also update the boilerplate code now and then so it can be used with the latest technology.
