Excerpt:
Mechanical devices to achieve speech synthesis were conceived of in the realm of fiction, and first devised in the early 19th century. The invention of the telephone in the late 19th century, and the subsequent efforts to reduce the bandwidth requirements of transmitting voice, led back to the idea. In the 1930s, the telephone engineers at Bell Labs developed the famous Voder, a speech synthesizer that was unveiled to the public to great fanfare at the 1939 World’s Fair, but that required a skilled human operator.
Fully automatic speech synthesis came in the early 1960s, with the invention of new automatic coding schemes, such as Adaptive Predictive Coding (APC). With those new techniques in hand, the Bell Labs engineers again turned their attention to speech synthesis. By the late 1960s they had developed a system for internal use in the telephone system, a machine that read wiring instructions to Western Electric telephone wirers, who could then keep eyes and hands on their work. Further progress led to the introduction, in 1976, of the Kurzweil Reading Machine which for the first time allowed the blind to "read" plain text as opposed to Braille. By 1978, the technology was so well established and inexpensive to produce that it could be introduced in a toy, Texas Instruments’ Speak-and-Spell. Thus, the development of this important technology from inception until fruition took about 15 years, involved practitioners from various disciplines, most of whom are still alive, and had a far-reaching impact on other technologies and, through them, society as a whole.
Annotation:
This site was established to record the history of artificial voice machines, software and research. Most notably, the site contains numerous oral history accounts by engineers and programmers who developed this field in the second half of the twentieth century, and it is looking to add more of these recollections online. A timeline provides an outline of the major advances in automatic speech synthesis and recognition, and visitors are asked to add their historical notes, photographs and audio clips from early voice technologies. The site maintains an extensive list of links to institutes of higher education and companies that have been at the forefront of artificial speech research and development. Short biographical outlines of important figures are also available, as are citations to seminal papers and reviews from this area of electrical engineering and computer science.
