Scientists may be a step closer to understanding the origins of human language. Two studies suggest that the ability to combine sounds and words to alter meaning may be rooted in a species of monkey. A team found the Campbell's monkey can add a simple sound to its alarm calls to create new ones and then combine them to convey even more information.

The giggling sounds of a hyena contain important information about the animal's status, say scientists. In the first study to decipher the hyena's so-called "laugh", they have shown that the pitch of the giggle reveals a hyena's age. What is more, variations in the frequency of notes used when a hyena makes a noise convey information about the animal's social rank.

If you want us to build a really robust speech model, we need a lot of phonemes, which is a syllable as spoken by a particular voice with a particular intonation. So we need a lot of people talking, saying things so that we can ultimately train off of that. ... So 1-800-GOOG-411 is about that: Getting a bunch of different speech samples so that when you call up or we're trying to get the voice out of video, we can do it with high...
