We can classify the ways that hard disk can breakdown in two: software and hardware. With the first I'm talking about the lost of data due to virus or accidental erasure. In these cases, if it's possible retrieve the information, it is often so cheap because only we have to use the appropriate software. Instead, the errors of hardware or physics are very expensive of repair, because are needed tools and specialized installations and only if the information that contains is enough valuable, can worth pay for it.

Over two hundred years ago, in 1779, Christian Kartzenstein did 5 whistles that made blew the vowels artificially. Few years after, in 1791, Wolfgang von Kemplelen presented his "Acoustic-Mechanical Speech Machine" that we could consider the first voice synthesizer because it could produce isolated sounds and some sound combinations. Deep in "The first voice synthesizer"

The voice synthesizers are those programs as Loquendo, which provide of human voice to the machine. Although the majority of them have a voice very robotic, without intonation and feelings, but we can understand it. Here you see roughly how is imitated the human voice in a computer and because is so difficult achieve a voice equal to the human one. Read the rest of "How works the voice synthesizers?"
