Maintenance Ask Me Anything ! PRs Welcome forthebadge made-with-python Made with Flutter Slack Status


  • The idea is to create an app, which have two parts speaker(host) and listeners. So, whenever the listener needs to ask doubt or interact with host it can raise hand in the app, or use hand gesture to ask doubt.

  • The app will also serve, the person who are disabled, can’t interact and miss important session, so we can use hand gesture-to-speech, wherein, a speech-impaired person could convey their messages using gestures on their smartphone’s front camera and it’d get converted to voice in real-time.

  • Moreover the hearing-impaired person can see the text spoken on their mobile screen, using speech to text converter.

  • It also happens that many a time there is language gap, so we can give a choice either to do translation of words from host language to listener language or to do transliteration, example Hinglish, as most time hindi is difficult to read, but hinglish can be easily read and understand.


  • Make a bridge to close the communication gap among us.
  • The regular listeners can raise hand button in app, so that they can use their mobile’s microphone to talk too host, and then host can * easily communicate with them.
  • Since, lip reading has accuracy of only 50% we will use gesture-to-speech with accuracy of 80%+.
  • Use of speech to text converter for hearing-impaired person.
  • Use of translation and transliteration, to convert host language to listeners language and vice versa.

Getting Started

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.


  • Any operating system (i.e. Linux, Windows, MacOS X)
  • A little knowledge of Dart and Flutter. Don't worry if you are new to it, you just need knack to learn.
  • Any IDE with Flutter SDK installed (i.e. VSCode, Android Studio, etc)
  • Any IDE for Python (i.e. VSCode, Pycharm etc)

Development Setup

The development environment requires a linux system with Python 3.7 and clone of the forked version of this repository.

Setting up the project

  • Download Flutter from the below link
  • Install Python
  • Installing Pipenv

We are using Pipenv for managing project development in a virtual environment and it is also the package manager here.

Why Pipenv?

Install Pipenv


Phase I

  • Look over the project and read the goals to be met for project.
  • Research more about implementation of Machine learning model, for transliteration.
  • Research more about implementation of Machine learning model, for hand gesture-to-speech

Phase II

  • Setting up goals.
  • Wirting testcases of for transliteration.
  • Testing of transliteration and hand gesture-to-speech

Phase III

  • Completing the project.
  • If time permits, we will setup AR subtitles, such that re can get live subtitle in prefered version.
