Introduction

I. INTRODUCTION

In our globalized world, language learning is becoming increasingly important. Learning a new language opens up new opportunities, whether it's for personal growth, professional advancement, or travel. However, learning a new language can be challenging, time-consuming, and costly. To address these challenges, we have developed the Indian Language Teacher application, a language learning platform that aims to help users learn Indian languages in an interactive, engaging, and personalized way.

The Indian Language Teacher application is a mobile app that offers an immersive language learning experience for users who want to learn Indian languages such as Marathi, Hindi, Tamil, Telugu, Kannada, and more. The application has been developed using Python in the backend, Flutter in the front end, and SQLite3 database. We have also used the Django Rest Framework to build a robust and scalable backend API. The user interface is designed to be user-friendly and intuitive, with interactive elements that engage and motivate the user to continue learning.

The Indian Language Teacher application offers a wide range of features and functionalities that are specifically designed to facilitate language learning. One of the key features of the app is the personalized learning experience. When the user first opens the app, they are prompted to select their preferred language and are given 3 options to choose from i.e. Characters, Words and Sentences.

The learning plan includes a variety of learning materials such as basic characters, vocabulary lists, and interactive exercises. The app is structured in such a way that the user first learns the basic characters of the language, then moves on to learning words, and then learns about sentences. There are various types of lessons included such as Intro chars, identifying letters from sounds, identifying sounds from words, choosing the correct word, choosing the correct sound, and so on. The same type of lessons are present for characters and words. For sentences, join the jumbled sentences, identify the sentence from audio, and identify the correct audio of the sentence. The grammar rules and vocabulary lists are presented in a structured and systematic way, making it easy for users to learn and retain new information. The interactive exercises are designed to be fun and engaging, with gamification elements such as streaks that motivate users to continue learning.

The application also includes advanced text-to-speech conversion features. This feature allows users to practice speaking and listening skills in a realistic and immersive way. The text-to-speech technology can convert text into natural-sounding speech, making it easier for users to practice listening skills.

The Indian Language Teacher application has been developed to address language learners' challenges. One of the biggest challenges is the lack of resources and time. Traditional language learning methods often require learners to attend classes or hire a private tutor, which can be expensive and time-consuming. This application offers a more convenient and cost-effective way to learn a new language.

Users can learn at their own pace and on their schedule, without the need for a classroom or tutor.

Another challenge that language learners face is the lack of motivation. Learning a new language can be a daunting task, and it's easy to get discouraged along the way. The application addresses this challenge by incorporating gamification elements that motivate and engage users.

In conclusion, the Indian Language Teacher application is an innovative and effective tool for language learners. It offers a personalized and engaging learning experience, with advanced features such as text-to-speech conversion. The app is designed to be user-friendly and intuitive, with gamification elements that motivate and engage users. The application has the potential to revolutionize the way we learn languages and make language learning more accessible and enjoyable for everyone.

III. METHODOLOGY

The creation of the app and making it unique among others is indeed not an easy task. It’s not only about selecting the perfect algorithm, rather it’s about making the algorithm work for you in the best way possible. Also, there are a few steps followed so that the application turns out to be error-free and unique among the others. The steps involved in teaching the language to the user include the collection of basic characters, words, sentences, audio generation, collection/creation of animations for buttons, and many more. Below is the Software Development Life Cycle (SDLC) of the application designed:

According to the above figure our SDLC is divided into 5 major phases Analysis, Design, Build, Testing and Maintenance. We begin by performing system analysis, and next we identify the requirements for developing the application. This took a total of 20 days. In the next phase i.e. the Design phase, we perform the System Design using Figma (a tool for UI Design). For designing the UI of the complete application, the team took a total of 24 days. In the next build phase, we coded the complete application from the scratch. For developing the system a total of 71 days were required. In the next 10 days, we performed testing of the application. The testing of the application included various approaches such as Black Box Testing, White Box Testing, Unit Testing, Integration Testing, GUI Testing, and Performance Testing. After making sure there aren’t any major bugs and defects in the system, we deployed the application which took us a total of 10 days. This time was used to understand the various system requirements of the users who might use the application and based on that study we deployed the application. In the remaining 5 days of time, Transitioning was performed.

IV. MODULES

A. User Module

The user module described is a system designed for user authentication and login. It operates by accepting the user's phone number and using Firebase to generate an OTP for verifying the user's identity. Once the user has been authenticated, their phone number and authentication token are securely stored in a database.

If the user's phone number already exists in the database, their progress is restored based on the authentication token. This means that the user can seamlessly resume their activity where they left off without having to log in again. If the user's phone number does not exist in the database, it is stored newly along with the authentication token.

The authentication token generated after successful authentication serves as a unique identifier for the user and is used to validate subsequent requests made by the user. This approach ensures that only authorized users can access sensitive information or perform important transactions.

Overall, this user module provides a robust and secure way to authenticate users and store their credentials for future use. It has a wide range of applications, including e-commerce, social networking, and banking. The use of Firebase for OTP generation adds an additional layer of security and reliability to the user authentication process. This system ensures that users can easily and securely access their accounts, making it an essential component of many modern applications.
