The first computer-based speech synthesis systems were created in the late 1950s, and the first complete text-to-speech system was completed in 1968. In 1961, physicist and colleague Louis Gerstman used an computer to synthesize speech, an event among the most prominent in the history of . Kelly's voice recorder synthesizer () recreated the song "", with musical accompaniment from . Coincidentally, was visiting his friend and colleague John Pierce at the Bell Labs Murray Hill facility. Clarke was so impressed by the demonstration that he used it in the climactic scene of his screenplay for his novel , where the computer sings the same song as it is being put to sleep by astronaut . Despite the success of purely electronic speech synthesis, research is still being conducted into mechanical speech synthesizers.

The speech in Natural Voices is "okay", but it is a bit boring. There are other good products too, but they are all for Windows, unfortunately)..
It infeclts surprisingl well sometimes .. but OMG, initially it is a pain! .. so #2 is *patience... and lots of updating of your "special words" list ... By patience, I mean you(I) actually became accustomed to my particular baboon's speech patterns :)... and by the way, I currently have about 3000 words that now sound "Human" enough that I no longer cringe when I hear them.

The quality of a speech synthesizer is judged by its similarity to the human voice and by its ability to be understood. An intelligible text-to-speech program allows people with or to listen to written works on a home computer. Many computer operating systems have included speech synthesizers since the early 1980s.

A recent study reported in the journal "Speech Communication" by Amy Drahota and colleagues at the , , reported that listeners to voice recordings could determine, at better than chance levels, whether or not the speaker was smiling. It was suggested that identification of the vocal features which signal emotional content may be used to help make synthesized speech sound more natural.

Many systems based on formant synthesis technology generate artificial, robotic-sounding speech that would never be mistaken for human speech. However, maximum naturalness is not always the goal of a speech synthesis system, and formant synthesis systems have advantages over concatenative systems. Formant-synthesized speech can be reliably intelligible, even at very high speeds, avoiding the acoustic glitches that commonly plague concatenative systems. High-speed synthesized speech is used by the visually impaired to quickly navigate computers using a . Formant synthesizers are usually smaller programs than concatenative systems because they do not have a database of speech samples. They can therefore be used in , where and power are especially limited. Because formant-based systems have complete control of all aspects of the output speech, a wide variety of prosodies and can be output, conveying not just questions and statements, but a variety of emotions and tones of voice.

The second operating system with advanced speech synthesis capabilities was , introduced in 1985. The voice synthesis was licensed by from a third-party software house (Don't Ask Software, now Softvoice, Inc.) and it featured a complete system of voice emulation, with both male and female voices and "stress" indicator markers, made possible by advanced features of the hardware audio . It was divided into a narrator device and a translator library. Amiga featured a text-to-speech translator. AmigaOS considered speech synthesis a virtual hardware device, so the user could even redirect console output to it. Some Amiga programs, such as word processors, made extensive use of the speech system.
