CSRE (The Canadian Speech Research Environment) is designed as a comprehensive, integrated, inexpensive, micro-computer-based workstation to support speech research. The focus of the project has been to develop the basic functionality required by speech researchers, using mass-produced, widely-available hardware. In its present form, CSRE includes: (1) waveform editors to capture, cut, paste, and measure signals; (2) facilities to produce colour spectrograms and waterfall displays from sampled data using a variety of spectral analysis techniques; (3) a parametric digital speech synthesizer, based on that developed by Klatt (1980); and (4) an experiment generator, developed to speed the programming of experimental sequences. The system requires an IBM/AT compatible computer (typically, Zenith Model 386 or Model 248, with math coprocessor and EGA or VGA graphics), a data acquisition system (e.g. Data Translation DT2801-A or ARIEL DSP-16, plus microphone, preamplifier and filters), and a Microsoft-compatible mouse
