Sine wave speech is artificially degraded speech that sounds like just beeps and whistles until you have been primed to hear it as speech.

Bacteria have invaded virtually every ecological niche on the planet. Human explorers of extreme environments such as deep wells and mines are still finding new bacterial species. "As you go deeper into the subsurface, thousands and thousands of feet, you find bacteria that have been isolated for millions of years - and you find multiple antibiotic resistance," Hazen said.
In his view, when bacteria develop resistance to modern antibiotics, they are merely rolling out old tricks they mastered eons ago in their struggle to live in harsh environments in competition with similarly resilient species.
Named by the British after Sir George Everest, the former British surveyor general, the 29,029ft mountain is the highest on Earth, and a major tourist attraction in Nepal.
Climbers aged between 15 and 71 have scaled its summit in the years since Edmund Hillary's 1953 triumph.
But it is not quite the virgin territory it was then. Recent visitors have described the mountain as a polluted rubbish dump.
According to the Kathmandu Post: "The trail leading to the summit remains littered with more than 200 tonnes of garbage."Read More
The view shows what might be the remains of a large impact crater covering most of this face, and which could be responsible for the somewhat flattened shape of the southern part of Epimetheus (116 kilometers, or 72 miles across) seen previously at much lower resolution.
The image also shows two terrain types: darker, smoother areas, and brighter, slightly more yellowish, fractured terrain. One interpretation of this image is that the darker material evidently moves down slopes, and probably has a lower ice content than the brighter material, which appears more like "bedrock." Nonetheless, materials in both terrains are likely to be rich in water ice.
The breakthrough, carried out at Manchester University, could help pave the way for a generation of drugs that would halt up to 90 per cent of cancers in their tracks.
Such drugs could be particularly effective against breast and lung tumors - two of the biggest killers.
More than 150,000 Britons a year are killed by cancer, and breast and lung tumors account for almost a third of those deaths.
