How a Nigerian Student Invented an AI Glove That Gives a Voice to the Speech-Impaired

A student of Abubakar Tafawa Balewa University (ATBU), Bauchi, Muhammad Habib Husaini, has developed a groundbreaking Artificial Intelligence (Ai) powered device that transforms sign language into audible speech, offering new hope to people with speech impairments.

Husaini, a Computer and Communication Engineering student, invented the device in the form of a glove—called the NHED Smart Glove—which captures hand movements and converts them into speech in real-time. By simply wearing the glove and signing, users can have their hand gestures translated into corresponding audio output, effectively giving them a “voice.”

According to the university’s official Facebook page, the invention utilizes pressure sensors embedded in the glove, which transmit data to an ESP32 microcontroller. This data is then processed and directed to an SD card module, which triggers the playback of matching audio.

What makes the NHED Smart Glove even more remarkable is that it is entirely homemade. ATBU noted that all the components were sourced and assembled by Husaini himself—a testament to his innovation and technical skills.

“This invention provides a cheap yet advanced alternative for people with speech impairments,” the university said. “Habib created the NHED Gloves to give them a means to communicate and restore dignity.”

Reflecting on the purpose of his innovation, Husaini stated:
“With the NHED Smart Glove, we are not just building a device; we are also restoring dignity and bridging the gaps in communication.”

The university has praised his work as a significant contribution to inclusive technology, underscoring the role of local ingenuity in solving real-world challenges.
