Node.js and React Speech-to-Text Demo

This is a simple app that demonstrates how to use the Google Speech-to-Text API in a Node.js and React application.

Requirements

• Node.js (tested with version 14.x)

• React (tested with version 16.x)

• Google Cloud Platform Service Account Key with Speech-to-text api permissions

  Follow this tutorial to create credentials and learn how to use the Google-Speech-To-Text API

Setup

1. Clone this repository: git clone https://github.com/untilhamza/Real-time-transcription-with-Google-speech-to-text-API.git

Frontend part

1. Navigate to the react-app project directory: cd stt-client
2. Install dependencies: yarn
3. Start the development server: yarn start
4. Navigate back to the parent directory : cd..

The app will now be running at http://localhost:3000.

Add Credentials

1. Make sure to get a Google cloud Service Account Key as shown in this tutorial
2. Download the generated Service Account key json file save it to the server folder as speech-to-text-key.json.

   This file name is already added to the .gitignore file but make sure not to push to github or any public repositories

3. Open the server folder and add this line in index.js file to add google credentials to our node js backend.

process.env.GOOGLE_APPLICATION_CREDENTIALS = "./speech-to-text-key.json"; //TODO: set this to the path for your Service account key JSON file

Backend part

1. Navigate to the server project directory: cd server
2. Install dependencies: yarn
3. Start the development server: yarn run dev
4. Start the development server: npm start

The backend listens at http://localhost:8081.

Usage

To use the app, simply click the "Start Recording" button and speak into your microphone. The transcription will appear on the screen as you speak, updating in real-time. When you're finished, click the "Stop Recording" button to see the final transcription.
