With commercial availability of non-real and real-time spectrum analyzers, the speech-language pathologist has the means to objectively extract and measure pitch taken from speech samples. Though both types of spectrum analyzers provide the clinician with viable methods of measuring fundamental frequency and frequency range values, pitch extraction using real time allows for greater efficiency in acoustic measurements. The Kay Elemetrics Visi-Pitch is one such real-time spectrum analyzer that is less expensive and more accessible than other real time speech science hardware. The purpose of this study was to investigate the capability of a computerized Visi-Pitch to reflect elevation of fundamental frequency and expansion of frequency range by female adults.
