The Computerized Speech Lab (CSL) is a speech and signal processing computer workstation (software and hardware) used for research and clinical speech therapy. Computerized Speech Lab (CSL™)is a highly advanced acoustic analysis system with robust hardware for data acquisition, complemented by a versatile suite of software available for speech analysis, teaching, research, voice measurement, clinical feedback, acoustic phonetics,and forensic work. KayPENTAX, a division of PENTAX medical, offers two CSL models, 4500 and 4150B. The latest generation CSL hardware, is an input/output recording device for a PC, which complies with the rigorous specifications and features needed for reliable acoustic measurements. It includes a state-of-the-art PCI hardware interface, using ASIO drivers for low latency (i.e., deterministic responsiveness) between the external module and the host computer, as well as a wealth of features ideal for speech analysis. Unlike systems built around generic, plug-in, multimedia sound cards, which were designed primarily for sound output, CSL, with its fully integrated hardware and software, is well tailored for sound input and measurement in the most exacting speech processing applications. CSL offers input signal-to-noise performance typically 20-30dB superior to generic, plug-in sound cards. CSL has been refined over ten years of continuous development to yield a rich set of standard features for speech analysis for teaching, research, voice measurements, clinical feedback, acoustic phonetics, second language articulation, and forensic work. Nineteen optional programs and databases target specific speech applications. CSL provides the necessary features and specifications for efficient, easy, accurate, and repeatable recording and measurement of speech signals for speech professionals.
