Stephen Hawking reportedly contributes vocals to a new Pink Floyd song, "Talkin Hawkin," which appears on the band's upcoming record, The Endless River.

According to Consequence of Sound, the physicist is credited in the full album credits, which leaked online.

Hawking speaks through a speech generating device, which was designed for him after he was diagnosed with an ALS-related motor neuron disease.

Endless River, an 18-track effort recorded during the sessions to the band's 1993 album, The Division Bell, hits November 10.

"The Endless River has its starting point, the music that came from the 1993 Division Bell sessions," says David Gilmour.

"We listened to over 20 hours of the three of us playing together and selected the music we wanted to work on for the new album."

"Over the last year we've added new parts, re-recorded others and generally harnessed studio technology to make a 21st century Pink Floyd album."
