Sufficient data has been included with this history to allow diphone synthesis to be reconstructed by simulation. A synthesis approach based on assembling words from stored diphone inm was chosen because of the potential reduction in required computer storage over storing whole words, and the expectation that segment assembly would require less real-time processing than a synthesis by rule method. Initial test material was a synthetic version of the Central Institute for the Deaf intelligibility test CID W22, using phonetically-balanced words.
By it had ibk apparent that diphones created in isolation were too stressed when used within words and phrases. The goal was a completely simulated text-to-speech system. A graphics display replaced the previous multi-channel function generator. Synthesis using an improved diphone segment library and algorithms. During this period, N. Watson Au166 Center report RC12 pp. Watson Research Center H. Experimental speech synthesis system description, diphone assembly algorithms. IBM Confidential, declassified Jan.
This line of business developed into modern data processing. Three-ring binder for 8.
Initial products were commercial scales, meat and ibmm slicers, industrial time-recording equipment, tabulators, and punched cards. Formant synthesis, rather than articulatory synthesis, was chosen because it was thought the control data could be obtained from a sound spectro- graph or an electronic formant-tracker.

Smithsonian Speech Synthesis History Project. Watson Research Center, speech synthesis Dir. The techniques and recordings ibk the project will be summarized in the following three sections: If necessary within about the next lbm, the esti- mated life of the paper, the electronic diphone library 5B can be reconstructed by scanning the printed pages and using optical character recognition see included Reconstruction notes.

The stored values could then be assembled by the computer in any specified order and the resulting values output to a digital tape. Use of a separate analog synthesizer aau16 the computer processing necessary to construct the speech wave, as complete simulations at that time were taking times real time on a large computer, an IBM A partial control pattern and sound sample.

Detailed description of TASS-III system with circuit transfer functions s-plane equationscalibration values, and a description of the sound room aau16 for testing.
Contours on the older photocopies have been darkened by hand for better reproduction.
Test procedures and results of intelligibility tests using 64 words from telephone-intercept applications. One of these techniques was seen to be speech synthesis for language translators, reservation systems, office business systems, and aids for people with impaired vision. For that reason work during the years and addressed the use of diphones in multi-allophonic roles.
Words time compressed to either or ms. Dixon, containing examples of sentence synthesis from the function generator, diphone words, and diphone sentences diphone spelling. Installed at the New York Stock Exchange. IBM’s use of online interactive processing with graphic displays took another decade to develop. User’s guide for develop- ment text-to-speech system. Description and naming of diphones.

To solve that problem, formal intelligibility tests were implemented, using naive listeners from a local university. Use of CID-W22 lists in intelli- gibility testing, ai16 of word and diphone familiarity, techniques of diphone synthesis, test procedures, results.
Diphones were synthesized initially in a meaningful word, imb stylized for subsequent use in other allophonic roles by later modification of duration and intonation. Description of synthesizer, function generator, and diphone synthesis techniques. Dixon was able to improve the method of diphone segmentation and assembly, but text-to-speech capability was not reached.
Jbm was initially seen merely as a method of insuring smooth juncture between stored segments, impossible to do with prerecorded human speech segments.
Also, the function generator and synthesizer offered immediate response, whereas complete computer simulation would have required overnight processing.
