Glottal Enterprises helps speech, voice, and singing research community with proven voice and speech measurement systems. Our products, found in universities and leading research centers worldwide, are based on more than 30 years of professional experience and innovative research in voice and speech measurement.
Glottal Enterprises was founded in 1981 by Martin Rothenberg, PhD, to offer other researchers the unique speech and voice measurement methods developed at the Speech Research Laboratory of Syracuse University. Glottal Enterprises products are largely based on Dr. Rothenbergs original research in speech, voice and language. His patented designs have brought researchers a broad line of tools, including the multichannel electroglottograph and aerodynamic measurement systems featuring the low distortion circumferentially vented mask developed by Dr. Rothenberg. Included are systems for voice measurement, as well as for the evaluation of nasality.
The research standard for noninvasive measurement of vocal fold vibration
The Glottal Enterprises electroglottographs produce very low-noise EGG waveforms and have the features most requested by researchers and clinicians. The unique, patented dual-channel configuration of the EG2-PCX2 enables it to indicate proper electrode placement and provide a quantitative indication of vertical laryngeal movement. The EG2-PCX2 model offers easy connection to a personal computer.
