NasalView is a new cost-effective, software/hardware system designed for the data acquisition, clinical analysis and treatment of nasal resonance disorders. NasalView provides real-time measurements of hypernasality and nasal emission via a simple graphic display with the added convenience and clinical utility of instant playback and database retrieval of all recorded speech samples. In addition, detailed spectral analysis (FFT; LPC; wide and narrow-band spectrograms) is also provided. Treatment of nasal resonance disorders is achieved through user-friendly tasks providing visual and auditory feedback to the patient. All of this is achieved using today's Window-based desktop and/or laptop PC's.
