Abstract: | |||||||
This thesis describes work undertaken in order to fulfil a need
experienced in the Department of Educational Enquiry at the
University of Aston in Birmingham for speech analysis facilities
suitable for use in teaching and research work within the
Department. The hardware and software developed during the
research project provides displays of speech fundamental
frequency and intensity in real time. The system is suitable for
the provision of visual feedback of these parameters of a
subject's speech in a learning situation, and overcomes the
inadequacies of equipment currently used for this task in that it provides a clear indication of fundamental frequency contours as the subject is speaking. The thesis considers the use of such equipment in several related fields, and the approaches that have been reported to one of the major problems of speech analysis, namely pitch-period estimation. A number of different systems are described, and their suitability for the present purposes is discussed. Finally, a novel method of pitch-period estimation is developed, and a speech analysis system incorporating this method is described. Comparison is made between the results produced by this system and those produced by a conventional speech spectrograph.
