Tone labelling algorithm for Sesotho

Raborife, Mpho 06 February 2012 (has links)
M.Sc., Faculty of Science, University of the Witwatersrand, 2011 / Studies have shown that text-to-speech systems need detailed prosodic models of a language in order to ideally sound natural to native speakers of the language. A text-to-speech system developed for Sesotho needs to have tone implemented in it since Sesotho is a tonal language which uses pitch variations to distinguish lexical and/or grammatical meaning. In order to implement tone for a language such as Sesotho, it is necessary for a tone modeling algorithm to receive as input the tone labels of the syllables of a word. This allows the algorithm to predict the appropriate intonation of the word. The aim of our study is to improve a basic tone labeling algorithm that predicts tone labels using three Sesotho tonal rules. The application of this algorithm is restricted to polysyllabic verb stems. The research study involves implementing an extended tone labeling algorithm that implements four additional Sesotho tonal rules and extends its application to all the other parts of speech. The results of our study show that the extended tone labeling algorithm significantly improves the basic algorithm by increasing the number of matched tone labels. Furthermore, our study provides the basic step to tone modeling for languages such as Sesotho which do not mark tone labels in orthography.

An historical survey of technology used in the production and presentation of music in the 20th Century

Lubin, Tom, University of Western Sydney, Faculty of Humanities and Social Sciences January 1997 (has links)
This paper explores the historical progression of the technological development of records and radio and its impact on popular music. It also includes the production technologies that create recorded music, the development of records, cassettes and CDs, and areas of reproduction that have an association with popular music including the sound technologies of radio, film, television, background music, and the juke-box. This paper is not a cultural or social study, but is primarily an historical account of media technology in music production and delivery. Certain social and cultural consequences and issues are included as background and sidebars to the primary topic. The technology of live performance has been omitted because it alone represents a body of material large enough for an entire paper. Western society now travels through a sea of music emanating from countless hidden sources. Such music delivery systems provide a continuous musical score for most people's personal histories. Sound, fragments of sound, and the very processes by which sound is created and manipulated have become products and commodities. The technology has allowed anyone to participate in the creation and hearing of music. This paper traces the history of the various technologies that, in so many respects, have provided a catalyst for that which is created, and the means by which music is listened to in the 20th Century. With rare exception, each new invention, delivery system, or process has had both supporters as well as detractors. Throughout this paper, both the positive as well as the negative effects of these developments will be explored. / Master of Arts (Hons)

Automatic segmentation in concert recordings

Ferguson, Robert W., III January 2004 (has links)
"...music is an art that exists in point of time." Aaron Copland, What to Listen for in Music / Few definitions are adequate to describe music, but a "point of time" is a concept with which people are familiar. When musicians give concerts they try to create these points in a context, which allows the audience to observe each moment by itself. Concert practice has developed to define the edges of musical points, guided by cues such as clapping, pauses, and concert program notes. / This masters thesis investigates how to analyze concert recordings of Western music and their program notes to produce segments which best fit the boundaries of musical points. Modern segmentation techniques are reviewed and a new method specific to concert recordings is examined.

The transfer and restoration of old recordings /

Rapley, Robert January 1993 (has links)
The process of remastering old recordings comprises two basic stages: the transfer of the material from the source to a modern format, and the subsequent restoration of the transferred material through various forms of signal processing. The transfer stage in particular requires an understanding of issues which are becoming increasingly less familiar to engineers as the science of recording progresses further into the digital era. To a lesser extent, the restoration stage involves the use of certain techniques and forms of processing which are specific to this application. / This thesis is intended as a reference for those recording engineers who occasionally undertake remastering projects, but who are not thoroughly acquainted with the many different situations and problems which can be involved. Emphasis is given to those areas which are likely to be least familiar to most engineers. / In order to enable the engineer to properly assess a given source, the evolution and characteristics of each type of source--cylinder, disc and tape--is surveyed. This is followed in each case by an examination of the preparation, equipment and method used in transferring the source. Finally, the various types of processing which can be applied to the transferred material are presented, focusing on the techniques and forms of signal processing which are specific to audio restoration.

Technology inna rub-a-dub style : technology and dub in the Jamaican sound system and recording studio

Lapp-Szymanski, Jean-Paul. January 2005 (has links)
This thesis attempts to chart the development of a Jamaican musical form known as dub. This development is considered primarily in terms of the island's encounter with a series of new playback, amplification, recording, and sound treatment technologies. Section I focuses on the formation of the Jamaican sound system (a network of powerful mobile discos) and its pivotal role in the birth of a fertile domestic record industry. Section II extends the investigation to the Jamaican recording studio and record industry. What distinguishes this work from others on Jamaican dub is its emphasis on technology, and theories of technology, within a geo-political framework. In Section I, this emphasis is most notably informed by the work of Harold Innis, Karl Marx and Lewis Mumford, with Marshall McLuhan and Walter Benjamin becoming more prominent in Section II. Key technologies in this analysis include mechanization (mechanical reproducibility), the Williamson amplification circuit, the House of Joy speaker, the dub plate (acetate phonograph) and vinyl record, twin-turntables and the microphone, the magnetic tape recorder, and perhaps most importantly, the multi-track recorder and interface (the multi-track mixing-board).

A comparative study of time-stretching algorithms for audio signals /

Markle, Blake L. January 2001 (has links)
Algorithms exist which will perform independent transformations on frequency or duration of a digital audio signal. These processes have different results different types of audio signals. A comparative study of granular and phase vocoder algorithms, implementation, and their respective effects on audio signals was made to determine which algorithm is best suited to a particular type of audio signal.
