Vaani AI — Making Communication More Inclusive with Speech Recognition and Indian Sign Language

Introduction

Communication accessibility remains a major challenge for many people, especially individuals with hearing or speech-related difficulties. While voice assistants and AI tools are becoming more common, many solutions still fail to address inclusive interaction for users who rely on sign language or real-time transcription.

To address this problem, I built Vaani AI — an Android-based accessibility application that combines real-time speech transcription and Indian Sign Language (ISL) interaction into a single platform.

Vaani focuses on making communication more accessible, interactive, and inclusive through AI-powered speech and gesture technologies.

The Problem

Many users face communication barriers in:

• classrooms

• public conversations

• meetings

• emergency communication

• daily interactions

Real-time voice conversations can be difficult to follow for users with hearing impairments, and sign language support is still limited across most mainstream applications.

Existing tools are often:

• expensive

• difficult to use

• not focused on Indian Sign Language

• lacking real-time interaction

I wanted to create a practical and lightweight solution that could work directly on Android devices.

What is Vaani AI?

Vaani AI is an accessibility-focused Android application that provides:

Real-Time Voice Transcription

The app continuously listens to speech and converts spoken words into live text captions.

Transcript Management

Users can:

• save transcripts

• view previous transcripts

• clear transcript history

• stop and store conversations instantly

Indian Sign Language (ISL) Mode

The app includes an ISL interaction module that uses computer vision for hand gesture detection and interaction.

Teach Sign Feature

One of the unique features of Vaani is the "Teach Sign" option, allowing users to train or demonstrate customized ISL signs for interactive learning.

Notification-Based Accessibility

Live transcripts can also appear through Android notifications, enabling quick access and multitasking support.

Technologies Used

Android Development

• Android Studio

• Java/XML

AI & Machine Learning

• MediaPipe for hand tracking and gesture detection

• Speech Recognition APIs

• Computer Vision pipeline

• Real-time transcription handling

Accessibility Features

• Live captions

• ISL interaction

• Background transcript support

⸻

How It Works

• User grants microphone and camera permissions

• Speech input is captured in real time

• Audio is converted into text captions

• Users can save or manage transcripts

• ISL mode activates gesture-based interaction using the camera

• "Teach Sign" allows customizable sign demonstrations

⸻

Challenges Faced

Building Vaani involved several technical challenges:

• handling continuous speech recognition

• managing Android background services

• reducing transcription delays

• implementing gesture tracking efficiently

• integrating real-time camera processing

Optimizing performance while maintaining accessibility was one of the biggest learning experiences during development.

Why This Project Matters

Accessibility technology should not be limited to expensive enterprise systems. AI can play a major role in building inclusive digital experiences for everyone.

Vaani is designed to:

• improve communication accessibility

• support inclusive interaction

• promote Indian Sign Language awareness

• demonstrate practical AI applications for social impact

⸻

Future Improvements

Planned future enhancements include:

• multilingual transcription

• offline AI support

• improved ISL recognition accuracy

• cloud synchronization

• AI-powered conversation summaries

• customizable accessibility settings

⸻

Conclusion

Vaani AI is more than just a speech transcription app — it is an attempt to use AI and accessibility-focused technology to make communication easier and more inclusive.

By combining speech recognition, computer vision, and Indian Sign Language interaction, the project demonstrates how AI can solve meaningful real-world problems at the community level.

Accessibility-driven innovation has the power to create a more inclusive future, and Vaani is one step toward that vision.
