Electronic speech synthesis : techniques, technology …
Domain-specific synthesis concatenates prerecorded words and phrases to create complete utterances. It is used in applications where the variety of texts the system will output is limited to a particular domain, like transit schedule announcements or weather reports.15 The technology is very simple to implement, and has been in commercial use for a long time, in devices like talking clocks and calculators. The level of naturalness of these systems can be very high because the variety of sentence types is limited, and they closely match the prosody and intonation of the original recordings.
Electronic Speech Synthesis by Geoff Bristow, …
Bell Labs first demonstrated an electronic speech synthesis device, the "Voder," developed by H.W. Dudley, at the 1939 World's Fair. The New York Times declared, in describing the machine's operation, "My God, it talks." This early analog system was the forerunner of Bell Labs work in articulatory synthesis, conducted by Cecil Coker in the 1960s, and Joe Olive's work on concatenative synthesis in the 1970s.
In the 1930s, Bell Labs developed the Vocoder, a keyboard-operated electronic speech analyzer and synthesizer that was said to be clearly intelligible. Homer Dudley refined this device into the VODER, which he exhibited at the 1939 New York World's Fair.
Speech synthesis is the artificial production of human speech
Aboutness has been studied from any number of angles. Brentano made it the defining feature of the mental. Phenomenologists try to pin down the aboutness-features of particular mental states. Materialists sometimes claim to have grounded aboutness in natural regularities. Attempts have even been made, in library science and information theory, to operationalize the notion. But it has played no real role in philosophical semantics. This is surprising; sentences have aboutness-properties if anything does. is the first book to examine through a philosophical lens the role of subject matter in meaning. A long-standing tradition sees meaning as truth-conditions, to be specified by listing the scenarios in which a sentence is true. Nothing is said about the principle of selection--about what in a scenario gets it onto the list. Subject matter is the missing link here. A sentence is true because of how matters stand where its subject matter is concerned. Stephen Yablo maintains that this is not just a feature of subject matter, but its essence. One indicates what a sentence is about by mapping out logical space according to its changing ways of being true or false. The notion of content that results--directed content--is brought to bear on a range of philosophical topics, including ontology, verisimilitude, knowledge, loose talk, assertive content, and philosophical methodology. Written by one of today's leading philosophers, represents a major advance in semantics and the philosophy of language.
Text-to-Speech Synthesis - Amazon S3
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 John Larry Kelly, Jr and colleague Louis Gerstman7 used an IBM 704 computer to synthesize speech, an event among the most prominent in the history of Bell Labs. Kelly's voice recorder synthesizer (vocoder) recreated the song "Daisy Bell", with musical accompaniment from Max Mathews. Coincidentally, Arthur C. Clarke 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 8 where the HAL 9000 computer sings the same song as it is being put to sleep by astronaut David Bowman. Despite the success of purely electronic speech synthesis, research is still being conducted into mechanical speech synthesizers.9They also use text to speech for a variety of youtube videos called "the secret missing episode of... These videos usually include cartoon characters such as Drew Pickles, Barney the dinosaur, and Ronald Mcdonald.

Early electronic speech synthesizers sounded robotic and were often barely intelligible. The quality of synthesized speech has steadily improved, but output from contemporary speech synthesis systems is still clearly distinguishable from actual human speech.
