The " Presentation Synthesis" test, of which this book is a part, is one of several educational helps on talk and reading, made available through the Bell System's High School Scientific research program. Various other material includes a classroom-oriented text message entitled, The Speech Cycle, a 19-minute color, audio film of the same title, and 4 classroom exhibition experiments. Presentation is an important subject matter in its own right; in addition , it is an excellent example of a topic that can be extensively understood simply by using the points of view and methods of investigation of a lot of disciplines, just like anatomy, physiology, acoustics, mindset and linguistics. The " Speech Synthesis" experiment is supposed to advance the student's understanding of speech production and acknowledgement. The electronic digital circuit, if perhaps assembled effectively, can produce a selection of vowel sounds. Experiments will be suggested that demonstrate a few of the acoustic and psychological factors involved in conversation perception. The written text also points out the importance of speech synthesizers as analysis tools for learning even more about processes of conversation and ability to hear. Finally, we discuss some of the possible uses of talk synthesizers in future communication devices. The " Speech Synthesis" material is intended primarily intended for capable biology and physics students in the secondary university level. Since no familiarity with electronics is essential for building the synthesizer, the biology student should not be unduly impaired. The chief requirements are patience and care, for it is definitely not a short task to mount and connect the many components that make up the synthesizer. An appendix on constructing the synthesizer, written by George R. Frost (who is also responsible for receiving the circuit into their present form), provides a lot of useful tips for trainees. The authors appreciate his efforts and feel that the appendix is a valuable addition to the publication. The authors are grateful to those who helped inside the preparation on this book. All of us owe a special debt to D. They would. Van Lenten, whose excellent editing improved its readability. His work to put together the work in the authors as well were important.
