What is it about?

What would an audible word cloud be like? This paper explores the idea of sung word clouds. This first attempt was one part of a six-part choral composition about the aftermath of sexual assault. The audible word cloud idea is extended to automatically singing a word list summary of any document using synthetic voices.

Why is it important?

1. This is a new approach to setting text for choirs. 2. It is a new way of composing. 3. It shows a new way of summarising text, suitable for the vision-impaired. 4. It challenges the current definition of "data sonification", which is the automatic generation of sound from data, the audio equivalent of data visualisation.


This paper combines my personal creative practice, my community work with choirs, and my research as a Computer Science academic. The choice of subject matter for the work is controversial, but adds another voice to the #metoo and related movements.
