To do this, first highlight your vocal track and then follow the instructions below to generate each effect: 1. If you'd like to sound like ... a robot Click on the Effect Menu and then Delay ... Change the Decay amount to 10 Change the Delay time to 0.009 Change the Number of echos to 30 Click OK Click on the Effect Menu again Click Repeat Delay Repeat this 5 times or more if necessary Listen to this example: Download Creating_a_robot_voice_in_Audacity.mp3 2. If you'd like to sound like ... a demonic spirit Click on the Edit Menu and then Duplicate Highlight the second track Click on the Effect Menu and then Change Pitch ... Change the Semitone (half-steps) to -1 Click OK Highlight the first track Click on the Edit Menu and then Duplicate Highlight the third track Click on the Effect Menu and then Change Pitch ... Change the Semitone (half-steps) to -5 Click OK Click on the Effect Menu and then Bass Boost ... Click OK Drag the Gain slide on the left of the third track to +3DB Highlight the second track Click on the Effect Menu and then Echo ... Change the Delay time (seconds) to 0.1 Change the Decay factor to 0.6 Click OK Listen to this example: Download Creating_a_demonic_voice_in_Audacity.mp3 3. If you'd like to sound like ... a chipmunk Click on the Effect Menu and then Change Pitch ... Change the Percent Change to 100 Click OK Listen to this example: Download Creating_a_chipmunk_voice_in_Audacity.mp3 4. If you'd like to sound like ... a telephone operator Click o

"This is a simple, elegant writing site for a collaborative writing. Users don't writing in real-time like so other sites, but exchange versions which clearly show the changes made. The other users can accept or decline the changes. It is useful for groups to draft their writing and for teachers correcting pupils work. Each version is archived in case the team changes their mind about the accepted changes."

Language in humans has evolved culturally rather than genetically, according to a study by UCL (University College London) and US researchers. By modelling the ways in which genes for language might have evolved alongside language itself, the study showed that genetic adaptation to language would be highly unlikely, as cultural conventions change much more rapidly than genes. Thus, the biological machinery upon which human language is built appears to predate the emergence of language. According to a phenomenon known as the Baldwin effect, characteristics that are learned or developed over a lifespan may become gradually encoded in the genome over many generations, because organisms with a stronger predisposition to acquire a trait have a selective advantage. Over generations, the amount of environmental exposure required to develop the trait decreases, and eventually no environmental exposure may be needed - the trait is genetically encoded. An example of the Baldwin effect is the development of calluses on the keels and sterna of ostriches. The calluses may initially have developed in response to abrasion where the keel and sterna touch the ground during sitting. Natural selection then favored individuals that could develop calluses more rapidly, until callus development became triggered within the embryo and could occur without environmental stimulation. The PNAS paper explored circumstances under which a similar evolutionary mechanism could genetically assimilate properties of language - a theory that has been widely favoured by those arguing for the existence of 'language genes'. The study modelled ways in which genes encoding language-specific properties could have coevolved with language itself. The key finding was that genes for language could have coevolved only in a highly stable linguistic environment; a rapidly changing linguistic environment would not provide a stable target for natural selection. Thus, a biological endowment could not coevolve with p

researchers long thought the window for learning a new language shrinks rapidly after age 7 and closes almost entirely after puberty. Yet interdisciplinary research conducted over the past five years at the University of Washington, Pennsylvania State University, and other colleges suggest that the time frame may be more flexible than first thought and that students who learn additional languages become more adaptable in other types of learning, too.

"Introduction In recent years, the world has witnessed a growing wave of local initiatives in support of public schools. Teachers, cultural associations and civil society have been playing an active part in grassroots experiments aimed at helping schools in the creative elaboration of new educational methods, also exploiting information technologies. Here answers are coming from those directly faced with educational issues, in contrast with the more common top-down reforms, where experts' committees draw up didactic experimentation plans to be put forward to willing teachers. Experiments like that are often very effective but, unfortunately, they rarely get known beyond the immediate sphere of their promoters. Moreover, they tend to be short-lived because promoters don't have the strength to sustain them and a suitable supporting network is lacking. They are like drops in the ocean: they apparently cannot change the entire educational system. But the ocean of whole human community could be flooded by many such contained experiments that would transform it, if the most meaningful of them could be fostered, spread and developed. ..."
