Many branches of the speech, hearing and singing research community use analyses of aspects of the voice source and overall spectral changes. By these means, patterned variations have been noted in both the voice source and the acoustic output from the vocal tract during speech and singing, the speech/singing of professional voice users and pathological speech. The widespread availability of fast computers and dedicated signal processing devices has enabled many of these techniques to be made available as real-time displays to a wide range of users. This paper describes a number of real-time visual displays of voice source, the acoustic output and articulatory gestures during speech and singing. The development of analysis techniques based on a model derived from the results of contemporary psychoacoustic experiments into the nature of the human peripheral hearing mechanism is discussed. This model depends on parallelism which is ideally suited to implementation on transpires which are specifically designed to operate in parallel. Developments such as these may further our understanding of the relative importance of voice source and acoustic cues in speech and singing, whether normal, professional or pathological, and enable a new generation of real-time visual displays to be implemented.

David M Howard, Dept of Electronics, University of York, Heslington, York, YOl 5DD, UK.
Dr David M Howard graduated in Electrical and Electronic Engineering from the University College of London from where he received his PhD in Human Communication from the Phonetics and Linguistics Department. He is at present a lecturer in the Department of Electronics at the University of York, UK. His research interests include the analysis and synthesis of singing and speaking voice, and in particular, the quantification of the effect of
voice training. Dr Howard is an ameteur singer himself, and ' also a competent organist and , choral director.
