Multi-Speech, Model 3700

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 brings KayPENTAX quality to the Windows-based software product category.

Applications

Multi-Speech is a comprehensive speech recording, analysis, feedback, and measurement software program. It includes the same analysis features as CSL, the most widely used speech analysis system. Multi-Speech also has numerous application-specific software options. It is only limited by the specifications, features, and S/N limitations typical of audio devices in the host computer. If you are using a professional-level device (e.g., CSL, DAT, ADAT, etc.), or your application does not require robust acoustic measurements, Multi-Speech is ideal. For measurements, or when budgets allow, consider a CSL system. Multi-Speech is also ideal as an option for CSL so that multiple users can analyze signals acquired by CSL.

Multi-Speech, with the caveats noted above, can be used for teaching, research, voice measurements, clinical feedback, second language articulation, and forensic work.

The screen above is from a sample macro and signal file delivered with Multi-Speech. Window A shows the IPA symbols time-linked to the speech waveform with glottal impulse markers. Other windows show a spectrogram with formant tracking, a pitch contour, an amplitude contour, and a palatogram, all linked together so that cursor movement shows the different palatometric patterns with the associated acoustic analysis.

Easy to Use

Although powerful, Multi-Speech is easy to use. Extensive online Help and tutorials guide the user. Commonly performed functions are on the toolbar or are accessed by defined keys (e.g., the F3 key plays the signal). All functions are available on the pull-down menus. A feature called macros stores a list of functions which can be recalled. Multi-Speech is delivered with many pre-written macros, and users can create their own as well. Macros make it easy to automate teaching lessons or clinical protocols. For example, Multi-Speech includes a macro that loads a speech file, filters the signal to sound like a phone connection, and illustrates the spectrum changes typical of a phone connection. Other macros automate clinical protocols so that evaluation and feedback with clients is quick and easy. Reports are easy because all graphic displays include complete numerical analysis and automatic statistical analysis.

Powerful

Multi-Speech software’s ease of use is complemented by the powerful feature set of the program. Every function can be adjusted to suit even advanced research requirements. For example, the spectrographic analysis has adjustments for nine filter bandwidths, four window weightings, full scaling, color, pre-emphasis, and dynamic range.

Comprehensive Graphical and Numerical Analyses

Comprehensive graphic and numerical analyses are available

The Video Phonetics Program shown above is one of several optional programs for Multi-Speech for targeted applications. Programs are targeted at clinical, teaching, and research applications.

Summary

Multi-Speech is a low-cost, powerful, and easy-to-use speech analysis program with many optional programs. These are ideal for research, teaching, and clinical applications. Multi-Speech, because it is based on the CSL (the leading speech analysis system), includes a wide array of functions and features for speech professionals.

Multi-Speech requires a host PC computer and sound device.
