Vocoding is the cross signals, sent those over a low-band synthesis of a musical instrument with phone line, and finally transformed voice. It was called the vocoder those signals back into the original because it involved encoding the speech, or at least a close voice (speech analysis) and then approximation of it. The vocoder was reconstructing the voice in also useful in the study of human accordance with a code written to speech, as a laboratory tool. replicate the speech (speech synthesis).

WIKI on ACCESSIBILITY Completion Report March 2010
WIKI ON ACCESSIBILITY Completion report March 2010 By Nirmita Narasimhan Programme Manager Centre for Internet and Society Project Title: Wiki on “Accessibility, Disability and the Internet in India” Page | 1 REPORT Accessibility wiki: accessibility.cis-india.org The wiki project was envisaged and funded by the National Internet Exchange of India (www.nixi.in) and has been executed by the Centre for Internet and Society (www.cis-india.org), Bangalore. Project Start date: May 2009 End date: February 2010. Background India has a large percentage of disabled persons in its population— estimated to be over seven per cent as per the Census of 2001. Even this figure is believed to be a gross under representation of the total number of disabled persons residing in this large and diverse country. Taken in figures, this amounts to roughly 70-100 million persons with disabilities in the territory of India. Out of this number, a mere two per cent residing in urban areas have access to information and assistive technologies which enable them to function in society and enhance their performance. There are several reasons for this, one of them being that there is a deplorable lack of awareness which exists on the kinds of disabilities and about ways in which one can provide information and services to disabled persons. Parents, teachers, government authorities and society at large are all equally unaware about the options which exist in technology today to enable persons with disabilities to carry on independent and productive lives. Barring a few exceptions, India is still trapped in an era where a white cane and a Braille slate symbolises the future for blind people, while the world has progressed to newer forms of enabling technology such as screen readers, daisy players, the Kindle and so on. -

Gnuspeech Tract Manual 0.9
Gnuspeech TRAcT Manual 0.9 TRAcT: the Gnuspeech Tube Resonance Access Tool: a means of investigating and understanding the basic Gnuspeech vocal tract model David R. Hill, University of Calgary TRAcT and the \tube" model to which it allows access was originally known as \Synthesizer" and developed by Leonard Manzara on the NeXT computer. The name has been changed because \Synthesiser" might be taken to imply it synthesises speech, which it doesn't. It is a \low-level" sound synthesiser that models the human vocal tract, requiring the \high-level" synthesiser control inherent in Gnuspeech/Monet to speak. TRAcT provides direct interactive access to the human vocal tract model parameters and shapes as a means of exploring its sound generation capabilities, as needed for speech database creation. i (GnuSpeech TRAcT Manual Version 0.9) David R.

It emulates the human vocal apparatus and allows \postures" to be imposed on vocal tract model, and energy to be injected representing voicing, whispering, sibilant noises and \breathy" noise. The \Distinctive Region Model" (DRM) control system that allows simple specification of the postures, and accessed by TRAcT 1is based on research by CGM Fant and his colleagues at the Stockholm Royal Institute of Technology Speech Technology Laboratory (Fant & Pauli 1974), by Ren´eCarr´eand his colleagues at T´el´ecomParis (Carr´e,Chennoukh & Mrayati 1992), and further developed by our original research team at Trillium Sound Research and the U of Calgary). -

First presented at the SMPTE 2014 Annual Technical Conference in Hollywood, CA, Oct. 20-24, 2014. © SMPTE 2014 FOR YOUR EYES ONLY! SMPTE Meeting Presentation The Origins of Audio and Video Compression: Some Pale Gleams from the Past Jon D. Paul, MSEE Scientific Conversion, Inc., Crypto-Museum, California, USA, [email protected] Written for presentation at the SMPTE 2014 Annual Technical Conference & Exhibition Abstract. The paper explores the history that led to all audio and video compression. The roots of digital compression sprang from Dudley's speech VOCODER, and a secret WWII speech scrambler. The paper highlights these key inventions, details their hardware, describes how they functioned, and connects them to modern digital audio and digital video compression algorithms. The first working speech synthesizer was Homer Dudley's VOCODER. In 1928, he used analysis of speech into components and a bandpass filter bank to achieve 10 times speech compression ratio. In 1942, Bell Telephone Laboratories' SIGSALY was the first unbreakable speech scrambler. Dudley with Bell Laboratories invented 11 fundamental techniques that are the foundation of all digital compression today. The paper concludes with block diagrams of audio and video compression algorithms to show their close relationship to the VOCODER and SIGSALY.
