We attach particular importance to the measurement and display of real, continuous speech and not simply sustained vowels. We manufacture and supply physical equipment for electrolaryngography, videoendoscopy and stroboscopy - and develop complementary software which performs a variety of analyses as well as integrating the results with other measures of the voice. These assist the therapist in work with clients on voice regularity, voice quality, pitch and loudness control. The patterns also provide crucial quantitative measures of the range, regularity and quality of the parameters being assessed. An important feature of the analyses is that they can be derived from samples of normal, continuous speech, in addition to isolated, sustained vowels.
New displays show nasality and frication.
Beyond this, we have recently added a stroboscopic system for video endoscopy of the vocal folds to our product range. The LxStrobe uses the laryngograph waveform for precise definition of the moment at which the imaging light flash is triggered. Images are then captured directly to the PC for display, analysis and playback. This provides a number of significant advantages over alternative approaches where triggers are based upon pitch extraction from the audio signal. LxStrobe allows greater accuracy of triggering, enables the disambiguation of images, and makes it possible to deal with irregularities in vocal fold vibration caused by speech pathologies.
