React Speech-to-Text Web App with Google Speech API

We need a simple Speech to text Web app with Client in React JS and Backend in NodeJS. The application should take direct speech (continuous speech) in the selected language and pass it to Google Speech to Text engine for it to convert the speech synchronously to the text in the selected language and display it on the browser. Application should also have a feature to accept audio file as input and send the audio file to Google STT engine for it to convert into text and display the text on the browser.
