Alexander Graham Bell — inventor of the telephone — may have died over 90 years ago, but you can still hear his voice today.

Smithsonian researchers recovered Bell's voice from a historical recording by using optical technology, Smithsonian Magazine reported.

The recording was recovered from a wax-and-cardboard disc that dates back to April 15, 1885, the magazine said.

Bell is credited with inventing the first telephone, and also making the first phone call back in 1876. It's chilling to hear his voice over a century later, especially considering the historical significance:

“In witness whereof — hear my voice, Alexander Graham Bell.”

Just imagine: Technology may never have evolved the same way — bringing us modern-day gadgets like the iPhone 5 and the Samsung Galaxy S4 — if it weren't for Bell's invention back in the 19th century.
