This paper investigates some of the ways in which composers and sound artists have used recordings of speech, especially in works mediated by technology. It will consider this within a wider context of spoken word, text composition and performance-based genres such as sound poetry. It will attempt to categorise some of the compositional techniques that may be used to work with speech, make specific reference to archive and oral history material and attempt to draw some conclusions.

Memory, according to Henri Bergson, is gleaned from the present and realises the present perception from its sensory-motor elements through movements towards that which it perceives.

The purpose of this article is to propose and debate the deliberate use of such ‘present memory’ in the sonic artwork. The suggestion is that sonic memory material – sounds that are plundered from old recordings – can be collaged into complex sonic works to produce, not a nostalgic experience in the sense of a recognition of the past, but a current production of sonic material in a continually present perception. Such a production strategy employs the affective quality of memory to ‘trigger’ a sensorial engagement in the sense of a ‘pathetic’ engagement understood as an emotional and sentimental involvement with the work. The understanding is that such an emotional engagement involves the listener centrally in the production of the artwork and challenges modernist (visual) art discourses, which evaluate the work from a distance.

Radio and memory form a radical coupling, stitching together musical cultures with personal psychologies. I pursue such relations in Phantom Music by focusing on, and unpacking a project I developed for exhibition in 2005. The project, Phantom Radio, is based on forming a library of radio memory. Collecting stories from 105 individuals from around the world, the library consists of written statements and CDs of all the songs mentioned. Through the project, questions of broadcast technology, and the work of memory, are brought forward. To pursue such questions, the following article maps out the territory explored in the project. Reflecting on various threads, from habits of listening to the effects of music on individual lives, leads to a tracing out of the ‘phantasmic’ and the ‘social’ aspects of radio. And further, how music supplies a form of shared ground to the individual instances of unexpected experiences.

The project Urban Song Paths took a traditional musical form, the Kaluli song path from Papua, New Guinea, and translated it for a contemporary urban situation. The Two Rivers Project explored a classic song path subject, the route of a waterway, in terms of two London rivers. A sense of place, the journey and the importance of the human voice were transferred from the Kaluli song path tradition into The Two Rivers Project, but other factors were necessary to create a truly urban song path form. Notions of dislocation, true and false memory, the changing functions of place and the unconscious effects of city zones were addressed by this work.

This paper provides an account of my current PhD research. It is conducted as an art project that involves both practice and theory. By taking Taiwanese sojourners in London as a case study, the research intends to present the emotional and cultural impacts they experience when they are immersed in the actual London soundscape. Following the proposed notion of ‘sonic constellations’, a few examples of audio works are demonstrated to analyse the relationships between sounds and the Taiwanese sojourners. Integrating art practice, soundscape studies, cultural studies and ethnography, the research is developed in an interdisciplinary way. The connected challenges taking place in various stages of the research, such as the pilot interview, will be addressed in this paper.

The unique sounds of the world's small-scale languages are being extinguished at an alarming rate. This article explores links between acoustic ecology and language ecology and outlines an approach to the creation of archive material as both source for and useful by-product of sound art practice and research. Through my work with endangered click-languages in the Kalahari Desert, it considers the boundaries between language and music and discusses the use of flat speaker technology to explore new relations between sound and image, portrait and soundscape in a cross-cultural context.

This paper has two main objectives: (i) to discuss essential concepts of the ecological approach to composition, proposing the term eco-composition as a common reference for theoretical perspectives and compositional techniques; and (ii) to present the multimedia piece Vivir sin después,realised within the context of the Paititi Project.

Following the Introduction, the paper is divided into two main sections. In section 2 we discuss issues raised by the application of the ecological approach to composition. Regarding the data-gathering procedures, eco-composition provides two effective methods: re-enaction and anchoring. Organisation of sonic materials is done through accumulation of heterarchical layers, giving rise to emergent musical phenomena. Section 3 dwells on the compositional strategies applied in the multimedia installation Vivir sin después. We describe the process of re-enacting the first Spanish trip through the Amazon River Basin, carried out by Francisco de Orellana and fifty-nine Spaniards in 1541. Then we address technical aspects of the piece, such as the application of multiple views of single entities, the development of non-hierarchical forms and the manipulation of sonic fields.

The Video Archive of Electroacoustic Music, an oral history project begun in 1996 by the author and sociologist, Barbara Cassidy, captures a first-person history of many pioneering electroacoustic music composers, scientists and engineers from 1950 to present. Transcript excerpts from The Archive are presented. Simultaneous with the founding of The Video Archive, the author began composing a series of pieces that draw on archival materials (from within and without The Video Archive) in a number of ways. Some possible compositional opportunities and approaches are mentioned and explored as embodied in the author's Left To His Own Devices (1996), and Crossing Boundaries (2000).

My research at the London College of Communication is concerned with archives of recorded speech, what new tools need to be devised for its manipulation and how to go about this process of invention. Research into available forms of analysis of speech is discussed below with regard to two specific areas, feature vectors from linear predictive coding (LPC) analysis and hidden Markov-model-based automatic speech recognition (ASR) systems. These are discussed in order to demonstrate that whilst aspects of each may be useful in devising a system of speech-archive manipulation for artistic use. Their drawbacks and deficiencies for use in art – consequent of the reasons for their invention – necessitate the creation of tools with artistic, rather than engineering agendas in mind.

It is through the initial process of devising conceptual tools for understanding speech as sound objects that I have been confronted with issues of semiotics and semantics of the voice and of the relationship between sound and meaning in speech, and of the role of analysis in mediating existing methods of communication. This is discussed with reference to Jean-Jacques Nattiez's Music and Discourse: Towards a Semiology of Music (Nattiez 1987). The ‘trace’ – a neutral level of semiotic analysis proposed by Nattiez, far from being hypothetical as suggested by Hatten (1992: 88–98) and others, is present by analogy to many forms of mediation in modern spoken communication and the reproduction of music, and it is precisely this neutrality with regards to meaning that tools for manipulation of speech must possess, since the relationships between the sound of speech and its meaning are ‘intense’ (after Deleuze 1968).

The birth of electroacoustic music is associated with an era of creativity which is now firmly embedded in the past. As the years advance so the opportunities for evaluating the pioneering years of the medium become increasingly remote. Few can now claim first-hand experience of working with the technologies that shaped and influenced the evolution of the early repertory, and many commentators are content to see them consigned to the museum. Others are less sure, having become aware of a number of features that appear to have no parallels in the modern all-digital domain. This article is predicated on the proposition that the functional characteristics of the equipment available during the formative years materially influenced the ways in which composers developed their compositional aesthetic. By studying the characteristics of the resulting interactions, important clues emerge as to the true nature of this engagement. Central to this study is the nature of the techné involved in these processes of creativity, and the significance of this is evaluated in the context of establishing a case for further research in this area. Particular attention is paid to the role of the tape recorder in this context, in particular its influence on the development of spatialisation techniques.
