Computerized Speech Lab (CSL)

The Computerized Speech Lab (CSL) is KayPENTAX’s most advanced speech analysis system with uncompromised specifications and performance. Indeed, CSL™ systems boast numerous citations in professional peer-reviewed journals for their broad range of application in analyzing speech and voice. Since its introduction a decade ago, CSL has become the instrument of choice for clinicians at leading medical centers and for university researchers. CSL is a complete hardware and software system. The companion CSL software and a rich array of speech analysis and biofeedback software packages are further described below.

KayPENTAX offers two versions of the CSL hardware: Model 4500 and Model 4150. Both platforms share many similarities, but Model 4150 is lower cost because, comparatively, it contains slightly reduced specifications. Although these differences are meaningful for some applications, CSL 4150 should be viewed as a highly cost-effective system depending on the user’s requirements.
The two CSL models are state-of-the-art input/output audio devices for a PC, and meet the exacting requirements for reliable acoustic measurements both in the clinic and for research.

Computerized Speech Lab (CSL) Model 4500

The latest generation CSL hardware, Model 4500, 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.

Computerized Speech Lab (CSL) Model 4150

CSL 4150 contains an external module with user controls and an internal plug-in card for the host computer. The external module offers many advantages over systems using an internal I/O card. Among these are convenient access to all input/output jacks (e.g. for microphone and headphones) and easy volume adjustments. During speech input, the signal level is readily adjusted with an external knob to ensure optimal data acquisition with the broad range of voice amplitudes encountered in the clinic.
CSL 4150 contains a DAT input connector allowing digitized data to be transferred directly through CSL hardware without having to be re-digitized. For the Voice Range Profile program, a calibrated input, which is activated by a switch on the external module, ensures precise dB SPL measurements. CSL hardware was designed from the ground up to meet the challenging demands of speech acquisition and accurate measurement.

Comprehensive Software for Speech/Voice Analysis

Complementing CSL hardware is a suite of some 20 software options. These include programs for patient assessment and therapy covering a broad range of communication disorders including voice, motor speech, fluency, and articulation. No other system provides the breadth of application-specific programs, many of which are frequently cited in peer-reviewed articles as the software tools of choice. The wealth of separate software options enables clinicians and researchers to tailor a CSL system to their work requirements. Various, cost-effective software “packages” are also available for different work settings. Additionally, CSL software includes a variety of databases and educational programs making it an ideal teaching platform for educators.

Multi Speech Model 3700- Low Cost Speech Analysis Software Multi-Speech, Model 3700, is a low-cost, Windows®-based, speech analysis program, which uses standard multimedia hardware (e.g., Sound Blaster™ boards) to capture, analyze, and play speech samples. Multi-Speech is a comprehensive speech recording, analysis, feedback, and measurement software program. It includes the same analysis features as the Clinical Speech Lab, the most widely used speech analysis system. Multi-Speech also has numerous application-specific software options. Multi-Speech can be used for teaching, research, voice measurements, clinical feedback, second language articulation, and forensic work.

Sona Speech II Model 3650

Sona-Speech™ II is a low-cost software package that is based on the acclaimed Visi-Pitch™ IV,(see below) also from KayPENTAX. Instead of using the robust hardware platform of Visi-Pitch IV, Sona-Speech II relies on standard sound cards for data acquisition and playback, making it an ideal choice for budget-minded clinicians. Sona-Speech II is used as a therapy tool for a broad range of speech and voice problems. It provides real-time visual feedback of important speech/voice<< <

Due to the performance limitations and variability of PC sound cards, KayPENTAX recommends Sona-Speech II primarily for routine therapy tasks, rather than for research or rigorous voice lab analysis. Sona-Speech II offers the clinician tremendous versatility, now with eight separate modules designed for assessment and treatment of voice, articulation, fluency, motor speech (dysarthria), and other communication disorders. Graphically interesting games are also provided to make therapy tasks appealing to children. Sona-Speech II brings the sophistication of KayPENTAX software found in Visi-Pitch IV to the sound card hardware environment. Clinicians will find Sona-Speech II a tremendous bargain and a powerful addition to their clinical tools.

The Visi-Pitch IV

The Visi-Pitch™ IV, is the latest version of the most widely used clinical instrumentation tool for speech-language pathologists. Encompassing the many features of previous generations of this acclaimed speech therapy tool, Visi-Pitch IV provides the latest, state-of-the-art, high-fidelity hardware for robust data acquisition and playback, and an additional software module. As a clinical tool, Visi-Pitch IV offers clinicians an unmatched assortment of powerful methods to assess and treat their clients.
Indeed Visi-Pitch is an indispensable tool in speech clinics worldwide. Its reputation has been earned by highly reliable performance and a versatile set of features. Now with eight standard modules, Visi-Pitch IV can be used with virtually every type of communication disorder in both assessment and therapy tasks. Critical speech and voice. <
