Communicating with a specially challenged person who can’t speak or hear is quite difficult, especially when you don’t know sign language.
So to ease this problem, today you will learn to make a Gesture Language Translator device that converts sign language into a spoken language. This device will be based on an ML model that can recognize the different sign language gestures for accurate translation.

Preparing The ML Model
There are different sign languages practised in different countries. For example, India uses Indian Sign Language (ISL) while the USA uses American sign language (ASL). So, you first need to decide which type you wish to implement.
After gathering the datasets, prepare the ML model for training. There are many options for this such as TensorFlow, Keras, PyTorch, Google’s Teachable Machine etc. For this project, I am using Google’s Teachable Machine, which is an online ML model creator service. Now, feed the datasets into your choice of ML model creator and capture the pictures of different hand gestures/signs with a camera. Remember to label them as per their meaning.
Deploying ML Model
Open the Raspberry Pi desktop and then create a new JS file. Shown below is Gesturetranslator.html. Paste the code snippet into the code and write the project name. Increase the canvas size so that the camera feed is clearly visible in a larger space. Save it.
