Effect of vowel duration on perceived intensity and quality. Research and Development, 8, The patterns were then taped to a transparent, endless mylar belt to be carried past a flying-spot scanner photos.

The stored values could then be assembled by the computer in any specified order and the resulting values output to a digital tape. The long patterns required up to five photocopies, in which the photocopies overlap. Human speech was manually edited to fit portions of words or phrases into the fixed ms time slots.

Formant synthesis, rather than articulatory synthesis, wu16 chosen because it was thought the control data could be obtained from a sound spectro- graph or an electronic formant-tracker. Description of synthesizer, function generator, and diphone synthesis techniques.

Speech synthesis from manually pre- pared patterns of whole sentences, read by the function generator.

The goal was a completely simulated text-to-speech system. Installed at the New York Stock Exchange. Bythe company name had been changed to International Business Machines Corporation, and a line of business based on a printing calculator had begun to dominate its sales.

Sufficient data has been included with this history to allow diphone synthesis to be reconstructed by simulation. Synthesis was initially seen merely as a method of insuring smooth juncture between stored segments, impossible to do with prerecorded human speech segments.


Synthesis using an improved diphone segment library and algorithms. Dixon, by then at the T. Watson Research Center report RC12 pp. Byit had become apparent that familiarization with the synthetic material limited the research staff’s ability to make further improvements in the synthesis.

If necessary within about the next years, the esti- mated life of the paper, the electronic au166 library 5B can be reconstructed by scanning the printed pages and using optical character recognition see included Reconstruction notes.

One synthesizer per telephone line. User’s guide for develop- ment text-to-speech system. Diphone-assembly logic starts on leaf 17 for 12 pages. A synthesis approach based on assembling words from stored diphone segments was chosen because of the potential reduction in required computer storage over storing whole words, and the expectation ay16 segment assembly would require less real-time processing than a synthesis by rule method.

A research project to revive the diphone synthesis work after ten years. Word time slots of ms on a magnetic drum, words maximum, available to 48 telephone lines simultaneously. Use of CID-W22 lists in intelli- gibility testing, effects of word and diphone familiarity, techniques of diphone synthesis, test procedures, results. By it had become apparent that diphones created in isolation were too stressed when used within words and phrases. Aylsworth, “Some effects of list familiarity and synthetic segment familiarity on the intelligibility of PB-words produced by diphone synthesis,” 70th meeting of the Acoust.

Initial test material was a synthetic version of the Central Institute for the Deaf intelligibility test CID W22, using phonetically-balanced words. Detailed description of TASS-III system with circuit transfer functions s-plane equationscalibration values, and a description of the sound room used for testing.

To solve that problem, formal intelligibility tests were implemented, using naive listeners from a local university. Dixon was able to improve the method of diphone segmentation and assembly, but text-to-speech capability was not reached. A graphics display replaced the previous multi-channel function generator. Test procedures and results of intelligibility tests using 64 words from telephone-intercept applications. K Truby, H. Notes on original function generator patterns. Analysis of the tests suggested which diphones needed to be improved, and which diphones were being confused.

Formant synthesizer implemented with operational amplifiers and controlled by an on-line computer with graphic display. Late in the year, additions to the function generator allowed the patterns to be sampled at millisecond intervals and punched into cards for entry into the IBM computer. The techniques and recordings of the project will be summarized in the following three sections: Use of a separate analog synthesizer avoided 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.

Watson Research Center Assoc.

The synthesizer control patterns were stored digitally in the computer in short units, mainly as consonant- vowel and vowel-consonant pairs. This was one of the first uses of intelligibility tests to diagnose problems with speech synthesis.

Truby coined the name “Diphone” for these segments.

Experimental speech synthesis system description, diphone assembly algorithms. Words time compressed to either or ms.

IBM Confidential, declassified Jan. This line of business developed into modern data processing. Description and naming of diphones. One of these techniques was seen to be speech synthesis for language translators, reservation systems, office business systems, and aids for people qu16 impaired vision.
