The use of real-time visual displays by Speech and Language therapists for the representation of voice source characteristics such as fundamental frequency (FO) and electrolaryngographically (LA-) derived vocal fold closed quotient (CQ) is now well established. This trend has been made possible by the widespread availability of fast computers and dedicated signal processing devices. However, many users of such equipment have expressed a need for a portable, battegl operated, device displaying FO and CQ, not only for specific use by the therapist but also for the use by clients outside the usual clinical consultation, where appropriate.Ar the University of York, we have developed a portable hand-held system based on the electrolaryngograph output waveform and a high performance microcontroller chip. The system can display graphically against time measures of f a larynx CQ and a normalised display of individual Lx cycles. This paper describes the development, implementation and the basic operation of the voice analyser system.As the power and more importantly the speed of computers has increased the use of real-time visual feedback displays of various voice related features have become well established [10,5]. A pilot study, by the authors, aimed at investigating the computing needs of speech therapists was carried out at a number of local hospital speech therapy departments. The results of the study indicated a requirement for a portable, battery operated, device capable of displaying in real-time a variety of voice related. features. Such a device would provide the therapist with a means of improving the effectiveness and objectivity of clinical assessment and therapy both in a clinical environment and a remote setting. Furthermore interest was also expressed in the opportunity a portable device may offer to enhance the measurement of clinical effectiveness.In the Department of Electronics at the University of York, we have developed a real-time voice analyser system which is portable, battery operated and can display graphically against time, measures of fundamental frequency, larynx closed quotient and a normalised display of individual electrolaryngography (Lx) cycles. This paper describes the development, implementation and brief operation of this voice analyser system.
