In 2025, a smart team at IIT Guwahati made something amazing! They built a new breath-to-voice technology. This new tool helps people who cannot speak. With this, even silent people can now talk using only their breath.
Let’s learn how this magic-like device works in very simple English.
🧠 What Is Breath-to-Voice Technology?
Some people cannot speak because of illness, accidents, or disability. But they can breathe.
This new tech uses AI (Artificial Intelligence) to:
-
Catch the sound of the person’s breathing
-
Understand what they want to say
-
Speak out loud using a computer voice!
This is like turning “air” into “words.”
🧪 Who Made This Device?
This device was created by:
-
Scientists at IIT Guwahati
-
AI researchers
-
Doctors who help people with speech problems
They worked together to build a CNN-based system (Convolutional Neural Network). This system is smart and can learn how each person breathes.

⚙️ How Does It Work?
This breath-to-voice system uses:
-
A small breath sensor worn near the nose
-
A machine learning model trained with that person’s breath pattern
-
A voice speaker that says the words out loud
Steps:
-
User breathes in a special way
-
Sensor catches the breath
-
AI figures out what word that breath means
-
Device says the word
👩🦼 Who Can Use This Technology?
This technology is a big gift for people who:
-
Lost their voice due to illness
-
Have speech disabilities
-
Cannot use their hands or keyboard
People with ALS, stroke recovery, or paralysis can now communicate using breath!
🧒 Very Easy Example for Kids:
Let’s say someone can’t speak. But if they breathe once, the machine says “Yes.” If they breathe twice, it says “No.” Just by breathing, they can talk!
The computer learns their breathing style and turns it into speech. 🎤
💡 Why This Innovation Is Important
This is one of the kindest technologies made in India:
-
Gives voice to silent people
-
Works without needing hands or keyboards
-
Gives freedom and dignity to disabled persons
-
Uses affordable parts and simple sensors
-
Can be used in homes and hospitals
🧠 What Is CNN AI?
CNN means Convolutional Neural Network. It is a type of computer brain (AI) that can learn from sound, images, or signals.
In this case, it learns how a person breathes. After that, it can guess what they want to say.
CNN helps the machine understand which breath pattern means which word.
🔊 What Can the Voice Say?
The AI system can say:
-
“Hello”
-
“Help me”
-
“I am hungry”
-
“Call doctor”
-
Or custom words for each person
It’s like building a small voice from air!
📲 Future Plans of the Project
The IIT team wants to:
-
Make the device cheaper
-
Make a mobile app for control
-
Share the tech with hospitals and schools
-
Add more languages like Hindi, Assamese, Bengali, etc.
