CSRE: A speech research environment

CSRE (The Canadian Speech Research Environment) is a comprehensive, microcomputer‐based system designed to support speech research using IBM/AT‐compatible micro‐computers. CSRE provides a powerful, low‐cost facility in support of speech research, using mass‐produced and widely available hardware. Functions include speech capture, editing, and replay; several alternative spectral analysis procedures, with color and surface/3‐D displays; parameter extraction/tracking and tools to automate measurement and support data logging; alternative pitch‐extraction systems; parametric speech (KLATT80) and nonspeech acoustic synthesis, with a variety of supporting productivity tools; and a comprehensive experiment generator/controller, to support behavioral testing using a variety of common testing protocols. The CSRE project is nonprofit, and relies on the cooperation of researchers at a number of institution. Version 3.0 of CSRE has been used since 1989 by researchers in 12 countries. Version 4.0 offers a wider range of functions, runs faster, uses higher resolution displays, and supports additional hardware systems, including digital signal processing boards.
